Polbionica Could Become the Next Success Story in Organ Bioprinting

Last year, a scientific team in Warsaw, Poland, bioprinted the world’s first prototype of a bionic pancreas with a vascular system. Led by clinical transplantation expert and inventor, Michał Wszoła, the specialists seek to introduce 3D bioprinting of the bionic pancreas to clinical practices worldwide in just over three years. The work, conducted at Polbionica, a spin-off company from the Foundation of Research and Science Development, will bring to market the research to 3D bioprint scaffolds using live pancreatic islands or insulin-producing cells to create a bionic pancreas, like the bioinks, bioreactor and the g-code files necessary to print bionic pancreas.

With more than 40 million people suffering from type I diabetes worldwide, this project holds a lot of promise. In Europe alone, seven million people are afflicted with the disease, with 700,000 of them undergoing serious complications.

The statistics alone offer a troubling overall pan of the disease. Even more so because, as Wszoła suggested in an interview with 3DPrint.com, hypoglycemia unawareness is a life-threatening complication that causes sudden death and is one of the major problems for type I diabetes; and the only method leading to a complete cure is a pancreas or pancreatic islet transplantation. But less than 200 pancreatic transplantations are carried out annually in Europe, which means that hundreds of people die while waiting for a transplant.

Polbionica is working to develop the key building blocks that support the development of the first bionic pancreas suitable for transplantation: bioink A for bioprinting bionic pancreas, bioink B for bioprinting vasculature, a novel bioreactor for growing organs, and a g-code file with specific bioprinting commands.

The company developed its own bioinks for this project and for bioprinting other organs of the body, while another bioink was used in 3D bioprinting of vessels with endothelial cells. Moreover, to carry out their research, they used Cellink‘s BioX bioprinter.

According to Wszoła, the organ based on bioprinted 3D cell-laden bioinks, functional vessels, and pancreatic islets would restore the body’s ability to regulate blood sugar levels and revolutionize the treatment of diabetes.

For now, the scientific team has the ability to bioprint a living organ of 3x5x3.5 centimeters, which consists of more than 600,000 islets equivalent that are retrieved from the donor and considered to be the suitable amount to cure a person with diabetes.

“Our next step is to replace the pancreatic islets with stem cell-derived alpha and beta cells. With this approach, the patient would not have to wait for donor cells since the pluripotent stem cells being used are derived from their own tissues,” indicated Wszoła, who is also a transplant and general surgeon. “So far, studies on animals proved that the use of established products was safe.”

“In order to reverse diabetes in humans, we need to have about one billion stem cells because efficacy to transform them into insulin-producing cells varies between 15% and 40%. I don’t believe that we will be able to solve the problem of brittle diabetes with transplantation of stem cell-derived islets (alpha and beta cells mixed into 3D organoids) alone,” he stated. “We should remember the lesson learned from pancreatic islet transplantation, whether we use original islets derived from a donor pancreas or produced from a patients’ stem cells, it will not solve the problem. In my opinion, we have to give those new islets a special nest, which involves an extracellular matrix through our bioinks and vessels with oxygen supply.”

Researchers at Polbionica have recently performed studies on mice proving that the bioprinted pancreatic petals using bioinks were well tolerated by the animals without any extended foreign body reaction to them. In April they will move onto studies with pigs and are planning studies with bigger animals together with Artur Kaminski, head of the Department of Transplantology and Central Tissue Bank at Warsaw Medical University.

“We expect clinical trials will be performed in Warsaw with the cooperation of our partners MediSpace Medical Centre and Warsaw Medical University. However, to begin this stage, we still have to overcome a few hurdles, like product stability, animal trials, approval from authorities as well as funding. If all that happens, just a few patients will be involved in the first stage of the clinical trial, mainly those who cannot receive any other treatment, and we have to remember that for the majority of people with diabetes, intensive insulin intake with CGM control is sufficient,” described Wszoła.

In 2012, diabetes expenses around the world accounted for 11% of the total health care expenditure. The Polish state needs close to one billion euros every year for diabetes. According to Wszoła, their potential competition, working on developing artificial pancreas is only offering a bridge treatment. Polbionica wants to go beyond that: their bionic pancreas could be a living organ that is a breakthrough in the treatment of type 1 diabetes.

He, along with his team hopes that their final product and know-how will solve problems related to the shortage of organs, postoperative complications and immunosuppression after transplantation, and above all, will be a chance to completely cure type 1 diabetes.

Moreover, the positive development of the organ production technology would significantly affect the general health of society, largely eliminating the problem of diseases associated with end-stage organ failure, reducing treatment costs, the need for social care, and professional absenteeism, while improving the quality of life of patients, and speeding up the process of introducing new drugs into the market.

“Bioprinting can have a great impact on the development of medicine, however, like every technology, it also has some limitations. We must remember that we are handling living cells, and the stress and other conditions which cells undergo during the bioprinting process has an influence on its function. Besides, we still have to work on better materials to build organs, materials that will keep cells together and allow them to function properly, materials with special strength, viscosity, and elascity,” claimed Wszoła.

The technology established by Polbionica even could let researchers bioprint vascularized organ models with cancer tumors to conduct research on the efficacy of newly implemented drugs. It may even revolutionize drug implementation routes and help diminish the need to perform animal studies.

“The field of drug testing can highly benefit from bioprinitng, with our technology we are now able to bioprint different pathologic models, such as pancreatic and liver cancers, melanomas, large bowel and breast cancer. We can also mimic microenvironments within tumors, print vessels and observe them in the lab when we add drugs and perform different analysis. In short, we can give a lot of answers and have an insight on drug development like never before.”

Polbionica is implementing the project as part of the Prevention Practises and Treatment of Civilization Diseases (STRATEGMED) program, funded by the Polish National Center for Research and Development. With experts in the fields of biotechnology, chemistry, mechatronics, bioprinting, and medicine, the team is moving forward quite rapidly in an area that to date has no cure, new technology can help patients reduce the burden of managing the condition, especially with regards to measuring their blood sugar levels and administering insulin, however, breakthroughs are not common. And although still in animal trials, the team is looking forward to the day when they will bioprint a bionic pancreas with living cells and tissues using their own bioinks.

Remet Opens Modern Metal 3D Printing Laboratory

Polish steel structures manufacturer for the oil and gs mining industry, Remet, has launched a metal 3D printing laboratory equipped with a range of high quality machines and devices. The first of these is the DMP Flex 350 by 3D Systems, followed by 3D Systems’ Figure 4, the office-friendly metallic powder atomizer ATO Lab, and plenty of other specialized research equipment. Remet completed the project together with 3D Lab, a top Polish industrial 3D printer distributor and manufacturer of the ATO Lab.

The ATO Lab metal atomizer, which enables testing and fabrication of many powdered metal alloys, was the starting point for this unique laboratory. A new branch of the enterprise, called Remet Metal Labs, is where the company will work on comprehensive additive manufacturing and industrial applications projects. Its goal is to create highly flexible conditions for creating prototypes in the powder production field, and automotive, aviation, and space industry customers are invited to work with Remet to take advantage of the lab. 3D Lab and Remet will present their solutions together at formnext in Frankfurt next month.

Innofil3D Materials and Design Rules Video

This week, Innofil3D, and its parent company BASF, have a lot of news to share. First up, Ultrafuse BVOH, its water-soluble support filament, is now available for purchase, along with its new Ultrafuse 316L metal filament. Designed for easy FFF 3D printing, this is the company’s first metal material – 80% stainless steel with a 20% polymer content.

Equispheres Releases Test Results for Unique AM Powder

Materials science technology company Equispheres has released the results from its first powder testing phase, completed by a facility that certifies AM materials for applications in aerospace and defense. The results have confirmed that the powder has exceeded expectations, allowing for a 20-30% increase in mechanical performance and a 50% increase in production speeds. In light of this news, Equispheres is launching new equity financing in order to, as the company wrote in a press release, “grow and unlock the vast potential of Additive Manufacturing.”

“The unique properties of our powder, including the high sphericity, narrow particle size distribution and low surface area results in significantly increased packing density. This allows an increase of powder layer thickness by a factor of 2 which significantly increases build speed. Most importantly, this boost to build speed does not come with a mechanical performance penalty. Instead, the uniform nature of our powder ensures that parts are produced with reliable and consistent mechanical properties. The minimal variance in our performance results provides design engineers the statistical confidence to produce stronger, lighter parts,” said Equispheres’ CTO, Dr Martin Conlon.

Hackaday Project: Micro Deltesian 3D Printer

A new Hackaday project by architect Ekaggrat Singh Kalsi was just published – a micro Deltesian 3D printer, which he says offers a quality that’s on par with any Cartesian 3D printer. The printer has a solid aluminum frame, with a standard slider Y axis and a Delta mechanism for the XZ axis. A 3.5″ LCD touchscreen, with a built-in SD card, is fast and easy enough for his young daughter to use, which was his ultimate goal. With an 80 x 100 x 85 mm build volume and a print bed held in place with magnets, the biggest challenge in making the minuscule 3D printer easy to use was the filament loading; Singh Kalsi used a lever-based latch mechanism for this.

“the micro deltesian was born out of the curiosity of building the convoluted deltesian mechanism,” he explained. “Later on it evolved into the idea of building a 3d printer simple enough to be used by my daughter. The deltesian mechanism seem very wierd when i first saw it but eventually i thought maybe i should give it a try and hence this printer was born.”

Watch the video below to see just how easily his daughter uses the micro Deltesian 3D printer:

Open Source DIY Telescope Prime Features Raspberry Pi and 3D Printed Parts

PiKon telescope

While the majority of us are not astronauts, there is a tool that can be used in your home to make you feel like you’re just a little bit closer to the stars – the telescope. Five years ago, a group of UK researchers from the University of Sheffield, including physicist Mark Wrigley, were inspired by NASA’s Juno spacecraft to create their own DIY telescope, the PiKon, using 3D printing and a Raspberry Pi. Now, a pair of Polish scientists have followed in their footsteps with their own parametric, open source, DIY telescope with 3D printed parts.

Aleksy Chwedczuk and Jakub Bochiński wanted to help popularize astronomy by making their own semi-professional, yet affordable, telescope model for at-home use, for which people can then download the files and create on their own. Chwedczuk and Bochiński call their creation the Telescope Prime, and created the first prototype in just eight hours. The initial prototype was then used to take pictures of the moon, and the final version was finished in less than three months.

The look from the inside of the Telescope Prime

Polish 3D printing company Sygnis New Technologies offered to help the scientists create their DIY telescope by sharing their equipment.

“As Sygnis New Technologies, we are proud to say that we have participated in the Telescope Prime project by adjusting 3D models of parts of the telescope and printing them for the science duo,” Marek Kamiński, the Head of Social Media for Sygnis New Technologies, told 3DPrint.com.

Telescopes have been helping people observe outer space since the 17th century, though at that time it was reserved only for the elite citizens who could purchase the equipment. But even though there is much more variety available today, it’s still not something that is widely available – the device has many complex, interacting elements. That’s why Chwedczuk and Bochiński wanted to use 3D printing to help create a more affordable, open source version.

In a piece by Sygnis, the two scientists said, “We wanted to initiate the development of an open-project telescope that could be easily modified and expanded…

“At the same time, it should be a digital telescope – adapted to our 21st century online lifestyle, where the habit of sharing one’s experiences on the Internet is the new norm.”

The telescope model, which all together costs less than $400 to put together, is made of three main parts: the 20 cm diameter parabolic mirror (with a recommended focal length of 1 m), a Raspberry Pi microcomputer with a camera and touch display, and 3D printed parts that are used to fix the camera and the mirror. To help keep costs down, “readily available materials,” like wood, screws, and a paper tube, are used to build the Telescope Prime.

Aleksy Chwedczuk with the first prototype of the telescope

In a further effort to keep the telescope fabrication as inexpensive as possible, it does not have lenses. Light is focused in a single spot, and stops on the mirror. A boarding tube makes up the body of the device, and plywood parts are then added. The telescope can use its build-in camera to take images of the night sky, and transmit them online in real-time using the touchscreen of a computer, projector, or tablet. Additionally, you can easily increase and reduce the size of the telescope – just enter the mirror’s size into the program, and all of its dimensions will be automatically converted.

“The creators had to take into account the realities of the 21st century, modern issues of the popularization of astronomy, also among the youngest amateurs of the starry sky, as well as the availability of materials for the construction of the telescope,” Sygnis wrote. “Telescope Prime is an innovative idea that reflects the needs and possibilities of an astronomer enthusiast of the second decade of the 21st century.”

The open source models for the telescope parts, which are available for download on the Telescope Prime website, were prepared in advance for 3D printing, so they didn’t need any corrections later. These elements were 3D printed on FlashForge 3D printers out of Orbi-Tech PLA material, and it took a total of 156 hours of printing to create the 17 telescope parts.

The final version of the Telescope Prime

Kamiński told 3DPrint.com that the two scientists are currently “promoting the project on Polish universities, schools and science institutes.” This makes sense, as the Telescope Prime website explains that the project was “initiated and fully carried out” on the grounds of the Akademeia High School in Warsaw.

3D Printing News Briefs: May 30, 2019

In today’s 3D Printing News Briefs, euspen plans to hold a Special Interest Group meeting in September centered around additive manufacturing, and an adjunct professor completed a comparison between a small SLS 3D printer and a large one. Moving on to interesting 3D printing projects, an artist teamed up with Mimaki to use full-color 3D printing to make a stage prop, a reddit user created an anti-cat button for an Xbox system, and an imgur user created a modular 3D printed fashion system.

euspen to Hold Special Interest Group Meeting on AM

The European Society for Precision Engineering and Nanotechnology (euspen) will be addressing the factors which are influencing an uptake of the use of additive manufacturing as a production technology at a Special Interest Group (SIG) meeting in September. The meeting, which will be co-hosted by the American Society of Precision Engineering (ASPE), will analyze the barriers to, and the opportunities for, the adoption of AM in production. It will be held from September 16-18 at the École Centrale de Nantes in France.

At the AM SIG meeting, issues that are, as euspen put it, “critical to the viability of AM as a production technology,” will be addressed. The co-chairs of the meeting are Professor Richard Leach from the University of Nottingham and Dr. John Taylor from the University of North Carolina at Charlotte. Local hosts and the organizing committee include Professor Alain Bernard from Centrale Nantes, Dr. David Bue Pedersen from the Technical University of Denmark, Professor Leach, and Dr. Taylor.

Comparison of Small and Large SLS 3D Printers

3D printers are often used in educational settings these days. Piotr Dudek, an adjunct professor at the AGH University of Science and Technology in Poland, runs a 3D printing lab at the school that both students and researchers frequent. While many technologies are used in the lab, SLS is the one that most interests Dudek, who decided to compare a big SLS system from EOS with the smaller Sinterit Lisa.

“We are using the big EOS SLS 3D printer for a long time and we wanted to compare it with Sinterit Lisa, check the possibilities of it. In SLS technology every detail matters. The temperature of the printing chamber, powder distribution system, heating or laser moving mechanism are very precise and important features. We wanted to test if Sinterit’s device is the valuable solution,” Dudek stated.

Larger 3D printers obviously have higher print volumes, but the down sides include difficult calibration, specialized training, and higher costs. In addition, it’s easy to mess up the calibration of a large 3D printer during transport. The Lisa 3D printer uses a gantry system, which comes pre-calibrated to save time, and it also uses less material, which means less money. The desktop printer is also much more student-friendly, making it the better choice for 3D printing labs like the one Professor Dudek runs.

Full-Color 3D Printed Stage Prop

A few months ago, 3DPrint.com heard from 3D printing specialist and Post Digital Artist Taketo Kobayashi, from the Ultra Modelers community, about an art exhibit in Japan that he helped organize which featured colorful, 3D printed works created on the Mimaki 3DUJ-553 full-color 3D printer. Recently, he reached out to us again with news of his latest Mimaki Engineering collaboration – a stage prop for the Japanese artist Saori Kanda, who performed with techno/trance band Shpongle at the Red Rocks Amphitheater in Colorado.

“It is a artwork,” Kobayashi told 3DPrint.com, “but also a utilization of full color 3D printing to entertainment field.”

The “Shpongle Mask,” which took 28 hours to print and mixed in Asian details, was worn onstage by Kanda as she performed her painting live with the band.

3D Printed Anti-Cat Xbox Button

reddit user Mbiggz was getting sick of their cat turning off the touch-sensitive button on the Xbox console while it was in use, which I can understand, having two cats of my own. So Mbiggz came up with the perfect solution – a 3D printed cover for the button. The design can be found on the maker’s Tinkercad account, as Mbiggz originally made the design for a Digital 3D class.

“Adhesive goes on the back part (it is labeled in the print). I’m a newcomer in terms of this so it’s not perfect,” Mbiggz wrote on Tinkercad. “Also, the door doesn’t open all the way, so you can fix it so that it does if you want to (even though it doesn’t really matter, there’s not really a need for it to open it all the way).”

3D Printed Modular Fashion System

hunter62610, a young imgur user, designed and 3D printed a Lego-like modular fabric system, which was featured in his school’s fashion show. He made two dresses that are made with a 3D printed prototype fabric pattern called Escher, which was designed to be “put together and taken apart” hundreds of times. It took him just two weeks to make the material, which the two young ladies who modeled the dresses said was fairly comfortable.

“The idea of the system is that theoretically, one could buy a fashion catalog filled with designs, and say 5000 links. Once could make every clothing item in the catalog, based on there needs. Perhaps that’s a pipe dream, but it’s a fun idea,” hunters62610 wrote.

“The Escher system is quite versatile. Each link acts like a free flowing Equilateral triangle, and has a male and female ball joint on each side. Every individual link is theoretically compatible with every other link. Special links are stored in the middle of this pouch that are really 3 merged links with a screw hole. If needed, these links can be used as elastic tie down points or buttons, if you screw in the buttons i made.”

A Makerbot Replicator Plus was used to print the fabric links in unique, small panels.

Polish Company CD3D Opens Largest 3D Bioprinting Cluster in Europe

Centrum Druku 3D, or CD3D, is the largest online website devoted to 3D printing technology in Poland. Launched in 2013 with an online portal, the company’s operations are based on two important pillars: providing knowledge in the 3D printing field, and scientific-research and R&D activities in the medical and pharmaceutical sciences. In 2014, CD3D held Poland’s first 3D printing awards, and this week launched a new medical project – the largest 3D bioprinting center in Europe.

The Open 3D Bioprinting Cluster launched in Lodz at the Bionanopark, which is one of the country’s largest laboratory complexes and works on multiple science and research projects in the medicine and biotechnology fields, including computational chemistry, 3D printing, biochemistry, and medical implants. CD3D, under the CD3D Medical brand, is the creator of the cluster, and will be operating it together with the Laboratory of Molecular and Nanostructured Biophysics at the complex, which also includes an incubator and conference center. In addition to bioprinting, CD3D Medical also offers SLA, FDM, and DMP 3D printing technologies.

21 3D bioprinters, created by CD3D and called SKAFFOSYS for ‘scaffold systems’, make up the cluster, and according to Pawel Slusarczyk, a Project Director at CD3D, they are the first Polish bioprinters.

The system uses a 5 ml syringe as a printhead, and performs extrusion mechanically, as semi-liquid, gel, and hydrogel materials are applied to a laboratory pan that’s been affixed to a working table. The SKAFFOSYS Lite 3D bioprinter features a 170 x 125 x 80 mm build area, with a process accuracy of 0.2 mm, and can also complete bioplotting. As more challenges are created over time by bioprinting projects, CD3D will expand the SKAFFOSYS Lite by adding new functionalities and modules.

Due to the teamwork between the Bionanopark and CD3D Medical, scientists are able to use additive bioprinting to complete comprehensive research and development projects in the biomedical engineering field. Under the close supervision of CD3D specialists and scientists from the Laboratory of Molecular and Nanostructured Biophysics, laboratories at the Bionanopark can now successfully complete, according to the website, “biochemical, biological and molecular research at virtually any stage of the creation of three-dimensional structures.”

The reason the 3D Bioprinting Cluster is so important is due to its open nature. We use 3D bioprinted structures for a myriad of purposes, from growing biological material on printed scaffolds and creating composite materials to researching alternative food sources and creating, studying, and testing out new types of biocompatible materials. So the fact that this large, new cluster for 3D bioprinting is open means that other external entities can use its important resources to complete tasks such as commissioning a comprehensive scientific and research service.

The partners and customers of the new Open 3D Bioprinting Cluster in Poland can now rest assured that the comprehensive service will make it possible to outsource scientific research projects to all of the laboratories in the Bionanopark.

Poland’s Emtel Uses 3DGence 3D Printers for Defibrillator Parts

The advantages of using 3D printing industrially are apparent around the globe. In the medical field, doctors are exploring ways to create necessary items like dentures, 3D printed implants, surgical models, and countless innovative devices that are not only enhancing the quality of life for many patients today, but in some cases, saving their lives too.

Defibrillators, used for shocking the heart back to life in the presence of arrhythmias, are medical devices definitely placed in the ‘saving lives’ category, and now Poland’s Emtel relies on 3DGence 3D printers for the fabrication of both prototypes and final parts for these machines that are vital to so many patients. Their most recent work has been demonstrated in a case study regarding low-volume production of 3D printed patient monitor prototypes and parts for defibrillators. The benefits abound in using such technology for manufacturing of small batches, allowing companies like Emtel to move forward in a fiercely competitive medical device market.

Prototypes are a necessary step in the manufacturing process, and ease in creation of such models is what led 3D printing technology to fame initially. For Emtel, this is critical in manufacturing cardiac monitor cases today; for example, in comparison to sending out prototype or part creation requirements to third parties, they can instead create them in-house and save substantially, while also reducing turnaround time from thirty days to a mere five.

“We print using a 3DGence printer a number of various mechanical details that could, without deterioration in strength and quality, replace some of the traditional aluminum and plastic parts used in our products so far,” says Wojciech Przybycień from Emtel. “The use of 3D printing technology allows us to more flexibly adapt to current production needs, reduce costs, as well as some kind of freedom when designing new devices.”

In using 3D printed parts for prototypes and devices, the Emtel team states that they perform extensive risk analysis and evaluation, along with comprehensive testing. In the end, they say their savings on the bottom line, thanks to 3D printing, can be up to three to five times less than it would be in using conventional processes.

“Production companies are sometimes confronted with problems related to the end of production of components or subassemblies supplied by external subcontractors. In such cases, the most common solution is to look for another sub-supplier, but it is worse in the case of unit or low-volume production,” says Wojciech Przybycień from Emtel. “In our case 3D printing turned out to be a solution. Owning a 3D printer and a good knowledge of its capabilities basically immediately suggested a solution to the problem, i.e. own design and production of casings for the defibrillator.”

Patient monitor prototype

In their recent case study using the 3DGence ONE 3D printer, Emtel was able to create a 3D printed patient monitor model prototype at 1:1 scale. In this case, costs were reduced by a staggering 90 percent, with one 3D Printed part priced at 50 EUR. Savings in time was up to 25 days less than usual, with models being made in around five days. Precision was excellent in this case, and ‘final details’ of the prototypes required no corrections. Significant improvements via 3D printing included:

Faster production of prototypes
More precise verification of ‘project assumptions’
Better ergonomy, installation, and validation of dimensions

“Additive manufacturing technology allows you to shorten the time needed by constructors and engineers to create and test products. Currently, 3D printing has ceased to be seen only as a tool used only for prototyping, evolving towards the printing of final products. Compared to traditional methods, it can positively affect the time and cost of production. This is due to the improvement of the quality, reliability and range of available materials in the cheapest FDM / FFF printing technology,” concluded Mateusz Sidorowicz from 3DGence company, regarding the recent case study with Emtel.

EMTEL Śliwa is a manufacturer of electronic medical equipment designed to monitor the biological parameters of the patient and for resuscitation. Their products are successfully used in Poland, other European countries, and Asia, South America, and Australia.

The 3DGence portfolio includes TÜV-certified 3D printers such as 3DGence INDUSTRY F340, a machine dedicated to industrial applications and 3DGence DOUBLE P255, a professional dual extruder 3D printer. Clients include GM, Fraunhofer Institute, Alstom, OSRAM and many more.

3D Printing News Briefs: December 19, 2018

In today’s 3D Printing News Briefs, a maker has published a free 3D print management app in the Play Store, while Formlabs works to continue accelerating its growth in the Asia Pacific region. America Makes has announced the winners of two Directed Project Opportunities, and a chemist employed by Sinterit has won a prestigious award. Finally, an engineer with a thirst for vengeance used 3D printing and a lot of glitter to get back at the people who steal packages from his porch.

Free 3D Printing App for Filament Management

A new app, simply called 3D Print, is now available to download for free on the Google Play Store. The app was published by a maker who goes by paratiDev on Google Play, and was developed to help other makers better manage their filament.

“It has happened to all of us, you want to print a piece and not to know for sure if you have enough filament in the coil to print it. If you have only one coil of that filament, you have only two options; you can use another filament that has more quantity or risk and print it,” paratiDev writes.

“In the first case it forces you to use another filament different from the one you wanted while in the second case you run the risk that there is not enough filament and the piece remains halfway, assuming a loss of money, filament and time.”

The app allows users to visualize how much filament they have left, view the history of 3D printed pieces they’ve made, and can also generate invoices and quotations for 3D prints. The free 3D Print app also allows you to create projects that group together several pieces, and will visualize the wight and total cost of the project.

Formlabs Continues to Grow in APAC Region

Today, Formlabs announced that its growth in the APAC region is continuing to speed up. The company, which first entered the China market in 2015, is planning to open its new APAC headquarters in Singapore soon, and has also completed a new warehouse in Shenzhen, China for more efficient processing and shipping. While its physical presence in the region is growing, so too is its headcount: Formlabs also announced that David Tan, previously the APAC director of strategy and programs for Oracle Cloud Platform, Alliances & Channels, has been hired on as a new general manager for its own APAC team.

Engineer Uses 3D Printed Component to Make Glitter Bomb

Revenge is a dish best served with glitter and fart spray…at least according to a mechanical engineer and evil genius Mark Rober. He spent nine years working at NASA’s JPL – mostly on the Curiosity Rover – and later founded a company called Digital Dudz. He was upset when someone stole a delivered package right off of his porch, and decided to employ all kinds of technology to take revenge.

“I just felt like something needs to be done to take a stand against dishonest punks like this,” Rober said in his YouTube video.

“I spent nine years designing hardware that’s currently roving around on another freaking planet. If anyone was going to make a revenge bait package and over-engineer the crap out of it, it was going to be me.”

Over the course of several months, Rober sketched his idea out, then finished it in CAD before getting to work on the physical prototypes. The package contains a 3D printed component that’s contoured in such a way that four hidden phones inside can capture package thieves opening the box and getting hit with a giant cloud of colorful glitter and continuous blasts of fart spray. Check out his video below to see how things turned out, though be warned that there is some bleeped out profanity. To learn more about the details of his build, check out his friend Sean’s video as well.

This spring, high-volume 3D printing factory Voodoo Manufacturing began its full-stack manufacturing and fulfillment service for 3D printing entrepreneurs, which allows users to outsource work like quality control and assembly for their products through its easy shopfront integrations with online marketplaces like Shopify. Now, the company has launched its own Shopify app, which will allow online sellers to create and customize 3D printed products and sell them on their own Shopify stores. Once the app is installed, users can make their first product in less than 5 minutes, which is then automatically added to their store, ready for purchase.

“We wanted to make it ridiculously easy for ecommerce stores to diversify their product offering with 3D printed products. By applying 3D printing to the print-on-demand business model, we are opening up an infinite range of product categories for Shopify merchants,” said Max Friefeld, the Founder and CEO of Voodoo Manufacturing. “The Voodoo app provides a new source of high quality, customizable, on-demand products, that don’t require any 3D design experience.”

Before the official launch this week, Voodoo piloted the service with a group of beta users, including It’s The Island Life by graphic designer and Guam native Lucy Hutcheson. She is already successfully selling six different products made with the help of the new Voodoo app.

BeAM Machines Partnering with Empa

BeAM, recently acquired by AddUp, has signed a research and development agreement with Empa, the Swiss Federal Laboratories for Materials Science and Technology. Together, the two will develop novel applications for BeAM’s powder-based Directed Energy Deposition (DED) technology, which uses focused thermal energy to fuse materials by melting them while they’re deposited. This makes parts manufacturing much faster. The partnership has come on the heels of Empa’s acquisition of a BeAM DED 3D printer, which is located at its Laboratory for Advanced Materials Processing in Thun and is used to integrate and test out innovative components.

Patrik Hoffmann, who leads the laboratory, said, “We are very excited to collaborate with BeAM’s engineers to push the boundaries of this innovative additive manufacturing technology and to develop a whole new range of applications for Swiss industries and beyond.”

Sculpteo 3D Printing Apartment Models

Together with Sculpteo, French property developer Valoptim is working to improve customer experience by providing clients with miniaturized 3D printed models of their future apartments when they sign their contracts, so they can better visualize and prepare for moving into their new home. These small, exact replicas give new owners an immersive experience, which is a definite value add. In addition, production of the 3D printed models is local, and can be done fast.

“Sculpteo uses the best machines and 3D printing processes on the market today. At first, we had the ambition to test the feasibility of 3D printing in the real estate sector. This innovative process has proven to be extremely interesting: the realistic rendering, with high-end finishes, allowed our clients to discover a miniaturized version of their future apartment enabling them to realistically imagine themselves living in it,” said Edouard Pellerin, CEO of Valoptim. “This innovation contributes to our business dynamic: constantly improving the customer experience.”

VSHAPER and Grupa Mac Sign Agreement

Polish 3D printer manufacturer Verashape has signed an agreement with Grupa MAC, the country’s top educational publisher, in front of Poland’s education curators at the recent Future of Education Congress. Per the agreement, Grupa MAC will use a network of educational consultants to distribute the VSHAPER GO 3D printers to kindergartens and other schools in the country. Grupa MAC recognizes that 3D printers are a good way to quickly present the effects of students’ learning, and the VSHAPER GO is the perfect choice, as it is easy to use and comes with an intuitive interface of SOFTSHAPER software.

“Classes with students are a perfect environment for the use of 3D Printing. Creating a pyramid model for history lessons, the structure of a flower or a human body for biology lessons are just a few examples, and their list is limited only by the imagination of students and teachers,” said Patryk Tomczyk, a member of the Grupa MAC Management Board. “We are happy that thanks to our cooperation with VERASHAPE, 3D Printers have a chance to reach schools through our network of educational consultants.”

3D Printing to be Introduced in UAE Primary Schools

Speaking of 3D printing in education, the Ministry of Education (MoE) for the UAE has announced that in early 2019, a country-wide introduction of 3D printing into over 200 primary schools will commence. As part of this new technology roll out, Dubai education consultancy company Ibtikar is partnering with Makers Empire, an Australian education technology company, to deliver a program that implements 3D printing and design. Makers Empire will supply 3D software, curriculum, teacher resources, training, and support to Ibtikar, which will in turn train MoE teachers to deliver the program.

“Through this rollout of 3D technology, our students will learn to reframe needs as actionable statements and to create solutions to real-world problems,” said HE Eng. Abdul Rahman of the United Arab Emirates Ministry of Education. “In doing so, our students will develop an important growth mindset, the skills they need to make their world better and the essential ability to persist when encountering setbacks.”

US Navy Approves Test of First 3D Printed Shipboard Part

USS Harry S. Truman

The US military has long explored the use of 3D printing to lower costs and increase the availability of spare parts. Huntington Ingalls Industries, the largest military shipbuilder in the US, has also been piloting new technologies, like 3D printing, as part of its digital transformation. In collaboration with the US Navy, the company’s Newport News Shipbuilding division has worked to speed the adoption of 3D printed metal components for nuclear-powered warships. This has led to an exciting announcement by the Naval Sea Systems Command (NAVSEA): a metal drain strainer orifice (DSO) prototype has officially been approved as the first 3D printed metal part to be installed on a US Navy ship. The assembly is a component for the steam system, which allows for drainage and removal of water from a steam line while in use. The 3D printed DSO prototype will be installed on the USS Harry S. Truman in 2019 for evaluation and tests. After one year, the assembly will be removed for inspection and analysis.

“This install marks a significant advancement in the Navy’s ability to make parts on demand and combine NAVSEA’s strategic goal of on-time delivery of ships and submarines while maintaining a culture of affordability. By targeting CVN 75 [USS Harry S. Truman], this allows us to get test results faster, so-if successful-we can identify additional uses of additive manufacturing for the fleet,” said Rear Adm. Lorin Selby, NAVSEA Chief Engineer and Deputy Commander for Ship Design, Integration, and Naval Engineering.

Lufthansa Technik Opens New Additive Manufacturing Center

Lufthansa Technik, a leading provider of maintenance, repair and overhaul (MRO) for civil aircraft, has established a new Additive Manufacturing Center. The goal of the new AM Center is to bundle and expand the company’s experience and competence with the technology, which can be used to make individual parts more quickly and with more design freedom. As the world of aircraft is always aware of weight, making more lightweight parts is an excellent benefit of 3D printing.

“The new AM Center will serve as a collaborative hub where the experience and skills that Lufthansa Technik has gained in additive manufacturing can be bundled and further expanded,” said Dr. Aenne Koester, the head of the new AM Center. “The aim is to increase the degree of maturity of the technologies and to develop products that are suitable for production.”

Polish 3D Printing Company UBOT3D Launches High Temperature Printer

There are a surprising number of 3D printing companies coming out of Poland. Vshaper and 3DGence are two emerging firms that both make high temperature printers. These are now joined by a colleague UBOT3D. UBOT3D is like many 3D printing companies moving up in the world making more expensive 3D printers that are capable of handling high performance materials such as PEEK and PEI. Acording to CEO Michal Melon , they’ve been around since “2015 and made and sold hundreds of 3D printers to polish and euroepan customers. Until this year we were focused strictly on the desktop market, but simultaneously designed an industrial grade machine using the same FFF technology.”

Ubot3D Build chamber.

Enclosed chambers, ventilation and higher quality is what many industrial customers want. Increasingly firms are heeding the call and making systems suited for the shop floor or for manufacturing rather than just sitting on someone’s desktop. Is the UBOT3D’s new system a capable one that can actually manufacture at scale? This is something we don’t know yet but if we look at the specs then the company at least is on a route to a promising device.

I sure hope this isn’t inside of it.

The P440 printer has a build volume of 440 x 330 x 300 mm and a 1500 W chamber heating system. It seems to have two ball screw and two linear guides inside of the chamber the guides seem enclosed but I wonder if the guides and ball screw will hold up like that. Specifically I’m wondering what will happen to the ball screw lubricant if the chamber becomes 400 C. The idea of having a seperate complete chamber heater is a solid one since lack of thermal control over the heated chamber and the wicking of heat is an issue with many high temperature 3D printers. If this system does maintain a constant temperature and can heat it up properly then this will be an advantage.

Ubot3D Build chamber.

The team also installed a four stage chamber filter of HEPA, carbon, PP and cold catalysis. Which sounds very safe indeed although I must confess to have no idea what cold catalysis is. The print bed is fastened with magnets, which is a nice feature, and it is powered by an 800 W heating unit. Which makes me think that its a good thing that there we do not yet have these EU energy efficiency ratings for printers. This should however give your bed a lot of heat and power which is great. Print bed maximum temperature is 150C, nozzle maximum is 400C. The 400 degrees is a tad limiting for some PEEK-like materials but if they have adequate chamber control they should be able to print most high performance materials. And they have automated leveling where, “the software creates the entire table image and then generates its image using the finite element method. This ensures that the print bed of the 3D printer will be calibrated correctly.” They say that their Hellfire hot end has been optimized for high temperature materials and the team has developed their own extruder as well as an own hot end. Its nice to see someone not using a E3D hot end, I would just hate it if Sanjay became too wealthy. The P440 also has automatic updating, a nice emergency off switch, expert mode and on board camera as well as an app to control the printer and can SMS you if there is an issue with the filament or if you’re running out and it costs 13,000 Euros which is $15,000. This makes it double the price of the Intamsys Funmat HT and more expensive than a Vshaper Pro and around 10k less than a 3Dgence Industry F340 and and around the price of an Intamsys Funmat Pro HT. If the performance is there then its a good price point to be at. But, it will have to be significantly better than a Funmat and a bit better than a Vshaper to even be considered by many. UBOT3D is at a sweet spot for HT printing but at the same time this is a part of the market that cares about performance and reliability above all else.

The Ubot does have two very unique features. Appearantly the printer, “has been equipped with the ability to order filaments directly through the device” and it can work for 30 minutes on auxiliary power if the lights go off. Yes people the days of chucking some rods and stepper motors into a box are gone. We have arrived in featureville, expect more features, demand more features. At first glance the UBOT3D has spent a lot of time thinking about features users care about. The things that their machines has on board are things that people do care about. It is exactly these features that allow for office friendly production that will get the next generation of corporate 3D printer customers.
