3D Printing News Briefs: October 16, 2018

We’re starting with some business news in today’s 3D Printing News Briefs, including stories about a new 3D printer, an anniversary, and a 3D printing investment. Cincinnati Incorporated has launched a new high temperature version of its SAAM 3D printer, and EOS will supply Visser Precision with five new metal 3D printers, including its M 400-4. VBN Components celebrates its tenth anniversary, and an Israeli 3D printing startup has received about $400,000 in funding. Researchers in Iran have successfully 3D printed flexible electronic circuits, and 3D printing was used to replicate a Chinese grotto. Finally, the Golf Channel will be featuring 3D printed golf clubs tonight.

New High Temperature Version of SAAM 3D Printer

Last week at FABTECH 2018 in Georgia, build-to-order machine tool manufacturer Cincinnati Incorporated (CI) launched a brand new high temperature version of its SAAM (Small Area Additive Manufacturing) 3D printer series. The SAAM HT 3D printer has a nozzle that can sustain temperatures up to 450°C and a bed temperature up to 260°C, which makes it possible to process materials like polycarbonate, PEEK, and ULTEM. Courtesy of its continuous patented automatic-ejection mechanism, the SAAM HT can be used for small batch production, and is a good choice for manufacturing tooling involved in high temperature operations.

“All materials compatible with SAAM can be used on the HT version. This level of versatility makes it a valuable asset in any manufacturing setting. We are enabling manufacturers and engineers to create the custom parts they need for their most demanding applications,” said Chris Haid, the General Manager of the NVBOTS Business Unit at CI.

EOS Supplying Visser Precision with New Metal 3D Printers

EOS M400-4

Denver-based Visser Precision, which provides advanced metals manufacturing solutions, has doubled its metal 3D printing capacity, thanks to the terms of an agreement reached with EOS at the recent IMTS trade fair. Visser has purchased three EOS M 400-4 3D printers, and two of the recently introduced EOS M 300-4 systems, making it the first organization to acquire the new platform. Market demands for DMLS-quality metal components in industries like aerospace and defense led Visser to grow its metal 3D printer capacity, and the new EOS systems will be delivered in a few months.

Ryan Coniam, the President of Visser Precision, said, “Our customers require the highest-performance, highest quality components and we feel partnering with EOS – the metal AM industry pioneers and leaders in DMLS – provides us with the capabilities we need to meet market demands now and in the next few years. Nearly anyone nowadays can 3D print something in metal, the trick is repeatability while meeting and maintaining quality and our investments with EOS mean we can deliver that to our customers.”

VBN Components Celebrating 10 Years in Business

Swedish materials development company VBN Components AB was founded in the midst of the 2008 financial crisis, and has come a long way since then. The award-winning company works to continuously develop new and better materials, including its corrosion and wear resistant Vibenite 350 for the plastics industry and Vibenite 290, the “World’s Hardest Steel.”

Martin Nilsson, CEO and one of the founders of VBN Components, said, “After our first patent, describing the process of making extremely clean and low-oxygen-rate materials, we realised that we were on to something big.”

This year, VBN Components is celebrating 10 years in business, with several patents and new, hard materials under its belt. But stay tuned – the company will soon unveil the greatest news in its history, which has been described as “a revolution in material development.”

TAU Ventures, the venture capital fund of Tel Aviv University, announced that it has led an investment round worth nearly $2 million for two Israeli startups, including Hoopo and 3D printing company Castor. Founded two years ago by Omer Blaier and Elad Schiller, Castor combines 3D printing with artificial intelligence for its high-tech customers, which enables the companies to lower costs by using advanced technology. Castor’s technology automatically analyzes and determines the cost-effectiveness and feasibility of using 3D printing in the manufacturing process.

The startup will be receiving about $400,000 in combined funding from Stanley Black & Decker, the Techstars Accelerator, British businessman Jeremy Coller, and TAU Ventures, which is the first and only academic-based venture capital fund in Israel.

3D Printing Flexible Electronic Circuits

Researchers from a knowledge-based company in Iran have recently developed 3D printers that can fabricate flexible electronic circuits, which could be used in the future as wearables for clothing, pressure sensors, or industrial talc for cars.

The unnamed company’s project manager, Ali Gharekhani, told Mehr News that these 3D printers only take a few seconds to 3D print the flexible electronic circuits, and that foreign versions of this system are “very expensive.” Gharekhani also said that in light of this new development, his company has already received some proposals for Turkey, and “intends to reach an agreement with the Turkish side on production of clothes by 3D printers” before its rivals in Germany, Canada, and Korea.

3D Printed Replica of Chinese Grotto

There are over 59,000 statues carved in 45 different caves in the 1,500-year-old Yungang Grottoes, which was named a UNESCO World Heritage site in 2001. This week, a full-size, 3D printed replica of one of the grottoes passed experts’ tests. The Yungang Grottoes Research Institute in northern China’s Shanxi province, a Shenzhen company, and Zhejiang University launched the project, which is based on original cave No 12, also called the “Cave of Music.” The 3D printed replica is 15 meters long, 11 meters wide, and 9 meters high, weighs less than 5 metric tons, and is claimed by the institute to be the world’s largest 3D printed movable grotto. High precision 3D data was collected to print the replica out of resin, which took about six months, and it can be divided in parts and pieced together within a week.

“We plan to color it with mineral pigments before the end of this year,” said Zhang Zhuo, head of the institute. “In this way, the replica will maintain its original size, texture and color.”

In the future, the 3D printed grotto replica will be added to exhibition tours with the institute’s other cultural relics.

3D Printed Golf Clubs on the Golf Channel

Tonight, at 9 pm EDT, EOS will be featured, together with Wilson Golf, on the NBC Golf Channel show Driver Vs. Driver. The seven-episode series follows aspiring designers of golf equipment as they compete against each other for the chance to win $500,000. In addition to the money, the winner will also have the opportunity to have their driver design sold, under the Wilson Staff name, at retail stores.

The show gives viewers a behind the scenes look as advancing teams work with engineers at the company’s innovation hub, Wilson LABS, to evaluate, refine, and test out their concepts. Tonight is the third episode, and showcases several designers’ use of 3D printing to make the best golf driver club. Wilson is among a few other companies, including Krone Golf, Ping, Callaway Golf Company, and Cobra Puma Golf, that is using 3D printing to produce golf clubs and other equipment.

3D Printing News Briefs: August 24, 2018

We’re sharing some business news in today’s 3D Printing News Briefs, followed by some interesting research and a cool 3D printed statue. Meld was listed as a finalist in the R&D 100 Awards, and Renishaw has introduced 3D printed versions to its styli range, while there’s an ongoing Digital Construction Grant competition happening in the UK. A researcher from Seoul Tech published a paper about in situ hydrogel in the field of click chemistry, while researchers in Canada focused on the Al10SiMg alloy for their study. Finally, an Arcam technician tested the Q20plus EBM 3D printer by making a unique titanium statue of Thomas Edison.

Meld is R&D 100 Awards Finalist

The global R&D 100 Awards have gone on for 56 years, highlighting the top 100 innovations each year in categories including Process/Prototyping, IT/Electrical, Mechanical Devices/Materials, Analytical/Test, and Software/Services, in addition to Special Recognition Awards for things like Green Tech and Market Disruptor Products. This year, over 50 judges from various industries selected finalists for the awards, one of which is MELD Manufacturing, an already award-winning company with a unique, patented no-melt process for altering, coating, joining, repairing, and 3D printing metal.

“Our mission with MELD is to revolutionize manufacturing and enable the design and manufacture of products not previously possible. MELD is a whole new category of additive manufacturing,” said MELD Manufacturing Corporation CEO Nanci Hardwick. “For example, we’re able to work with unweldable materials, operate our equipment in open-atmosphere, produce much larger parts that other additive processes, and avoid the many issues associated with melt-based technologies.”

The winners will be announced during a ceremony at the Waldorf Astoria in Orlando on November 16th.

Renishaw Introduces 3D Printed Styli

This month, Renishaw introduced a 3D printed stylus version to its already wide range of available styli. The company uses its metal powder bed fusion technology to provide customers with complex, turnkey styli solutions in-house, with the ability to access part features that other styli can’t reach. 3D printing helps to decrease the lead time for custom styli, and can manufacture strong but lightweight titanium styli with complex structures and shapes. Female titanium threads (M2/M3/M4/M5) can be added to fit any additional stylus from Renishaw’s range, and adding a curved 3D printed stylus to its REVO 5-axis inspection system provides flexibility when accessing a component’s critical features. Components with larger features need a larger stylus tip, which Renishaw can now provide in a 3D printed version.

“For precision metrology, there is no substitute for touching the critical features of a component to gather precise surface data,” Renishaw wrote. “Complex parts often demand custom styli to inspect difficult-to-access features. AM styli can access features of parts that other styli cannot reach, providing a flexible, high-performance solution to complex inspection challenges.”

Digital Construction Grant Competition

Recently, a competition opened up in the UK for organizations in need of funding to help increase productivity, performance, and quality in the construction sector. As part of UK Research and Innovation, the organization Innovate UK – a fan of 3D printing – will invest up to £12.5 million on innovative projects meant to help improve and transform construction in the UK. Projects must be led by a for-profit business in the UK, begin this December and end up December of 2020, and address the objectives of the Industrial Strategy Challenge Fund on Transforming Construction. The competition is looking specifically for projects that can improve the construction lifecycle’s three main stages:

  • Designing and managing buildings through digitally-enabled performance management
  • Constructing quality buildings using a manufacturing approach
  • Powering buildings with active energy components and improving build quality

Projects that demonstrate scalable solutions and cross-sector collaboration will be prioritized, and results should lead to a more streamlined process that decreases delays, saves on costs, and improves outputs, productivity, and collaborations. The competition closes at noon on Wednesday, September 19. You can find more information here.

Click Bioprinting Research

Researcher Janarthanan Gopinathan with the Seoul University of Science Technology (Seoul Tech) published a study about click chemistry, which can be used to create multifunctional hydrogel biomaterials for bioprinting ink and tissue engineering applications. These materials can form 3D printable hydrogels that are able to retain live cells, even under a swollen state, without losing their mechanical integrity. In the paper, titled “Click Chemistry-Based Injectable Hydrogels and Bioprinting Inks for Tissue Engineering Applications,” Gopinathan says that regenerative medicine and tissue engineering applications need biomaterials that can be quickly and easily reproduced, are able to generate complex 3D structures that mimic native tissue, and be biodegradable and biocompatible.

“In this review, we present the recent developments of in situ hydrogel in the field of click chemistry reported for the tissue engineering and 3D bioinks applications, by mainly covering the diverse types of click chemistry methods such as Diels–Alder reaction, strain-promoted azide-alkyne cycloaddition reactions, thiol-ene reactions, oxime reactions and other interrelated reactions, excluding enzyme-based reactions,” the paper states.

“Interestingly, the emergence of click chemistry reactions in bioink synthesis for 3D bioprinting have shown the massive potential of these reaction methods in creating 3D tissue constructs. However, the limitations and challenges involved in the click chemistry reactions should be analyzed and bettered to be applied to tissue engineering and 3D bioinks. The future scope of these materials is promising, including their applications in in situ 3D bioprinting for tissue or organ regeneration.”

Analysis of Solidification Patterns and Microstructural Developments for Al10SiMg Alloy

a) Secondary SEM surface shot of Al10SiMg powder starting stock, (b) optical micrograph and (c) high-magnification secondary SEM image of the cross-sectional view of the internal microstructure with the corresponding inset shown in (ci); (d) the printed sample and schematic representation of scanning strategy; The bi-directional scan vectors in Layer n+1 are rotated by 67° counter clockwise with respect to those at Layer n.

A group of researchers from Queen’s University and McGill University, both in Canada, explain the complex solidification pattern that occurs during laser powder bed fusion 3D printing of the Al10SiMg alloy in a new paper, titled “Solidification pattern, microstructure and texture development in Laser Powder Bed Fusion (LPBF) of Al10SiMg alloy.”

The paper also characterizes the evolution of the α-Al cellular network, grain structure and texture development, and brought to light many interesting facts, including that the grains’ orientation will align with that of the α-Al cells.

The abstract reads, “A comprehensive analysis of solidification patterns and microstructural development is presented for an Al10SiMg sample produced by Laser Powder Bed Fusion (LPBF). Utilizing a novel scanning strategy that involves counter-clockwise rotation of the scan vector by 67° upon completion of each layer, a relatively randomized cusp-like pattern of protruding/overlapping scan tracks has been produced along the build direction. We show that such a distribution of scan tracks, as well as enhancing densification during LPBF, reduces the overall crystallographic texture in the sample, as opposed to those normally achieved by commonly-used bidirectional or island-based scanning regimes with 90° rotation. It is shown that, under directional solidification conditions present in LPBF, the grain structure is strictly columnar throughout the sample and that the grains’ orientation aligns well with that of the α-Al cells. The size evolution of cells and grains within the melt pools, however, is shown to follow opposite patterns. The cells’/grains’ size distribution and texture in the sample are explained via use of analytical models of cellular solidification as well as the overall heat flow direction and local solidification conditions in relation to the LPBF processing conditions. Such a knowledge of the mechanisms upon which microstructural features evolve throughout a complex solidification process is critical for process optimization and control of mechanical properties in LPBF.”

Co-authors include Hong Qin, Vahid Fallah, Qingshan Dong, Mathieu Brochu, Mark R. Daymond, and Mark Gallerneault.

3D Printed Titanium Thomas Edison Statue

Thomas Edison statue, stacked and time lapse build

Oskar Zielinski, a research and development technician at Arcam EBM, a GE Additive company, is responsible for maintaining, repairing, and modifying the company’s electron beam melting (EBM) 3D printers. Zielinski decided that he wanted to test out the Arcam EBM Q20plus 3D printer, but not with just any old benchmark test. Instead, he decided to create and 3D print a titanium (Ti64) statue of Thomas Edison, the founder of GE. He created 25 pieces and different free-floating net structures inside each of the layers, in order to test out the 3D printer’s capabilities. All 4,300 of the statue’s 90-micron layers were 3D printed in one build over a total of 90 hours, with just minimal support between the slices’ outer skins.

The statue stands 387 mm tall, and its interior net structures show off the kind of complicated filigree work that EBM 3D printing is capable of producing. In addition, Zielinski also captured a time lapse, using an Arcam LayerQam, from inside the 3D printer of the statue being printed.

“I am really happy with the result; this final piece is huge,” Zielinski said. “I keep wondering though what Thomas Edison would have thought if someone would have told him during the 19th century about the technology that exists today.”

3D Printing News Briefs: August 7, 2018

We’re starting things off on today’s 3D Printing News Briefs with a little business and a little software, before moving on to more cool 3D printing projects and products. NextFlex has announced its Project Call 4.0, and we’ve got a closer look at a 3D print filament recycling system that was introduced at the Barcelona Maker Faire. OnShape has announced the latest updates to its CAD system. A university student 3D printed a car muffler, and Printable Science presents its 3D printed safety razor.

NextFlex Project Call 4.0

Last month, the NextFlex consortium, one of the leaders in the Manufacturing USA network, announced the award recipients of $12 million in funding for the latest round of its extremely successful Project Call program for Flexible Hybrid Electronics (FHE) innovations. This week, the consortium announced the $10 million funding round for its Project Call 4.0, which has a “very diverse scope of needs” that represent gaps in capabilities and technology in multiple application areas. Proposals should focus on several manufacturing thrust areas (MTA), such as flexible battery integration, FHE device encapsulation, evaluating and developing connectors for e-textiles and FHE devices, and advanced 3D electrical design software, among others.

“NextFlex’s Project Call process has proven to be extremely successful. We continuously tackle member-identified FHE manufacturing challenges, and with 31 projects already underway from three previous project calls, we expect this to garner even more interest from the FHE community,” said Dr. Malcolm J. Thompson, the Executive Director of NextFlex. “Topics in Project Call 4.0 build upon successful developments and learning from our previous project calls.”

OUROBOROS 3D Printing Recycling System

The Barcelona Maker Faire was held earlier this summer, and one of the many innovations on display at the event included an all-in-one recycling system for 3D printing called the OUROBOROS. The system shreds used plastic and extrudes the material into a 3D printable filament. According to YouTube user Joan Cullere, the OUROBOROS system includes a prototype shredder with a 24 V motor that’s almost completely 3D printed itself.

In addition to the economic and compact shredder prototype, the OUROBOROS 3D printing recycling system features a user-friendly filament extruder with better cooling, a new spooling system, and an optimized filament path. To see the new system for yourself, check out the video below.

Onshape System Updates

Modern CAD platform Onshape introduced the premium edition of its software in May, and delivers automatic upgrades to the system every three weeks. The latest updates, from July 12 and August 1, include many new improvements to the Onshape CAD system.

For instance, the July 12 update introduced a feature for adjusting the line thickness in drawings, which allows users to define the thickness for tangent, hidden, and visible edges. This update also added a new Drawing Properties panel icon, which replace the wrench icon and includes several new features. The August 12 update made it possible for users to change existing parts or assemblies to a revision, which means every stage of the workflow can be changed. In addition, users can now enjoy significant rebuild time improvements in the system’s complex multi-part Sheet Metal Part Studios. The next updates should arrive on August 23rd.

3D Printed Car Muffler

University student and YouTube user Cooper Orrock was inspired by another maker’s DIY project – a duct tape and cardboard car muffler – to make his own 3D printed version. He designed the two-component automotive part and 3D printed it in plastic; then, with the help of some friends, he prepared the part for installation on a vehicle. This included clearing out some of the holes on the rim of each part so it could be screwed together, and removing the original muffler from the car.

“Part of me thinks that it could possibly melt just because of all the heat from the engine and stuff, but part of me thinks it could work,” Orrock said.

To see if his prediction came true, check out the video below.

3D Printed Safety Razor

Printable Science, which creates “all the science that’s fit to print’ according to its Patreon page, creates all sorts of nifty 3D printed projects, like a socket nut driver, a mini hacksaw handle, and a USB microscope stand. Now, it’s moved on to a 3D printed, four part plastic safety razor.

“Forget the dollar shave club… forget paying shipping and handling… 3D print your own safety razor and be part of the 29 cent shave club,” a member of Printable Science said on the YouTube video.

He explained that the basic design of the safety razor has been mostly unchanged for about 150 years, and that with the design for this razor, you can make your own for just 19 cents. However, this isn’t the first 3D printed razor we’ve seen – in fact, the Gillette Company filed a patent for a 3D printable razor cartridge a few years ago, and was also one of the co-creators of a challenge to design a 3D printed razor handle. To see how Printable Science’s 3D printed plastic safety razor compares, check out the video below.

Update On Made In Space’s 3D Printed Asteroid Spacecraft Research

California 3D printing and space technology firm Made In Space is responsible for such out of this world innovations as the first commercial 3D printer on the International Space Station, the multi-armed 3D printing space robot Archinaut, and the manufacture of the first extended 3D printed objects in a space-like environment. The company works closely with NASA, and two years ago received funding from the agency for its ambitious plan to turn asteroids into autonomous spaceships, which could help NASA finalize its long-term goal of constructing human colonies in space.

Right now, NASA can only bring back small pieces of space rock. But Project RAMA (Reconstituting Asteroids into Mechanical Automata) hopes to establish the concept feasibility of using analog computers and mechanisms – along with 3D printing – to convert asteroids into huge mechanical spacecraft, which could carry large amounts of raw asteroid material. This could be the impetus for the off-Earth mining that will be necessary if humanity wants to survive and thrive among the stars.

Asteroids are pretty cool – many of them contain valuable resources, such as water and platinum-group metals, and roughly 100 tons of asteroid and comet material hit the Earth’s atmosphere each day. As part of the plan to turn these massive rock formations into functioning spacecraft, Made In Space plans to send an advanced, robotic seed craft out to space, in order to to meet with several near-Earth asteroids.

This craft would then harvest space rock material and turn it into feedstock, which can be 3D printed to build energy storage, navigation, propulsion, and other important systems on-site. Once the converted asteroid is ready, it can be programmed to autonomously fly to a mining station; according to Made In Space representatives, this approach is far more efficient than having to launch new capture probes out to space rocks.

While we don’t currently have the ability or the technology to 3D print something like a digital guidance computer with materials found on an asteroid, Made In Space realized that one doesn’t have to rely on digital electronics if a huge amount of raw material, with no constraints on mass or volume, is available instead.

“At the end of the day, the thing that we want the asteroid to be is technology that has existed for a long time,” said Made In Space Co-Founder and CTO Jason Dunn. “The question is, ‘Can we convert an asteroid into that technology at some point in the future?’ We think the answer is yes.”

Two years ago, NASA’s Innovative Advanced Concepts (NIAC) program, which encourages development of space-exploration technologies, awarded Made In Space a $100,000 Phase 1 grant for nine months of initial feasibility studies. During this phase, the company focused on how the seed craft would have to work, defining its requirements, and building a technological roadmap. If the company chooses, it can also apply for a two-year, $500,000 Phase 2 award for continuing concept development. In the meantime, Made In Space is counting on NASA to push forward in-situ resource utilization (ISRU) – the art of living off the land, which is necessary for astronauts who could someday live on planetary outposts.

Required capabilities of the RAMA craft, arranged in approximate order of mass requirements, showing the source of the materials used to provide each capability as assumed for the rest of this study.

These asteroid ships will probably not look much like traditional spaceships, with their electronic circuitry and rocket engines, but instead would use analog computers and a catapult type of propulsion system that will launch asteroid material in a controlled way. By using mass drivers to shoot chunks of itself in one direction, an asteroid could potentially accelerate itself in the opposite direction. While this method is only about 10% as efficient as a chemical rocket engine, the propellant is free.

3D printing could be used to make some of the asteroid spacecraft parts, like flywheel gyros for guidance and stabilization, tanks for storing volatile materials, and solar concentrators to generate mechanical power through the release of pressure to open the tanks.

While Project RAMA is still moving forward, Dunn acknowledges that its completion is still way in the future…and that eventually, it could even have applications on Earth.

Dunn explained, “The anticipation is that the RAMA architecture is a long time line, and when it becomes capable is about the same time that people really need the resources.

“You could build infrastructure in remote locations somewhat autonomously, and convert resources into useful devices and mechanical machines. This actually could solve some pretty big problems on Earth, from housing to construction of things that make people’s lives better.”

The other goal of Project RAMA is to be able to make asteroids into self-assembled spacecraft.

“One of the big questions is, how do you take today’s most intricate machines and make them replicate themselves? That seems really hard: how do you replicate electronics and processing units and so on,” Dunn said. “And that’s when we had this concept that there are types of machines that could potentially be easy to self-replicate, and those would be very basic, analog type devices. The problem is if you have a small mechanical machine, it’s not very useful. But what if the machine itself was the size of an asteroid? What could you do with a mechanical machine that large?”
