3D Printing News Briefs: February 8, 2019

We made it to the weekend! To celebrate, check out our 3D Printing News Briefs today, which covers business, research, and a few other topics as well. PostProcess has signed its 7th channel partner in North America, while GEFERTEC partners with Linde on 3D printing research. Researchers from Purdue and USC are working together to develop new AI technology, and the finalists for Additive World’s Design for Additive Manufacturing 2019 competition have been announced. Finally, Marines in Hawaii used 3D printing to make a long overdue repair part, and Thermwood and Bell teamed up to 3D print a helicopter blade mold.

PostProcess Technologies Signs Latest North American Channel Partner

PostProcess Technologies, which provides automated and intelligent post-printing solutions for additive manufacturing, has announced its seventh North American Channel Partner in the last year: Hawk Ridge Systems, the largest global provider of 3D design and manufacturing solutions. This new partnership will serve as a natural extension of Hawk Ridge Systems’ AM solutions portfolio, and the company will now represent PostProcess Technologies’ solution portfolio in select North American territories.

“Hawk Ridge Systems believes in providing turnkey 3D printers for our customers for use in rapid prototyping, tooling, and production manufacturing. Often overlooked, post-printing is a critical part of all 3D printing processes, including support removal and surface finish refinement,” said Cameron Carson, VP of Engineering at Hawk Ridge Systems. “PostProcess Technologies provides a comprehensive line of equipment that helps our customers lower the cost of labor and achieve more consistent high-quality results for our 3D printing technologies, including SL (Vat polymerization), MJF (Sintered polymer), and ADAM (Metal) printing. We vet our partnerships very closely for consistent values and quality, and I was impressed with PostProcess Technologies’ reputation for reliability and quality – an ideal partnership to bring solutions to our customers.”

GEFERTEC and Linde Working Together on 3D Printing Research

In order to investigate the influence of the process gas and the oxygen percentage on 3DMP technology, which combines arc welding with CAD data of metal parts, GEFERTEC GmbH and Linde AG have entered into a joint research project. The two already work closely together – Linde, which is part of the larger Linde Group, uses its worldwide distribution network to supply process gases for 3D printing (especially DMLS/metal 3D printing/LPBF), while GEFERTEC brings its arc machines, which use wire as the starting material to create near-net-shaped parts in layers; conventional milling can be used later to further machine the part after 3D printing is complete.

The 3D printing for this joint project will take place at fellow research partner Fraunhofer IGCV‘s additive manufacturing laboratory, where GEFERTEC will install one of its 3D printers. The last research partner is MT Aerospace AG, which will perform mechanical tests on the 3D printed parts.

Purdue University and USC Researchers Developing New AI Technology

In another joint project, researchers from Purdue University and the University of Southern California (USC) are working to develop new artificial intelligence technology that could potentially use machine learning to enable aircraft parts to fit together more precisely, which means that assembly time can be reduced. The work speaks to a significant challenge in the current AM industry – individual 3D printed parts need a high level of both precision and reproducibility, and the joint team’s AI technology allows users to run software components in their current local network, exposing an API. Then, the software will use machine learning to analyze the product data and build plans to 3D print the specific parts more accurately.

“We’re really taking a giant leap and working on the future of manufacturing. We have developed automated machine learning technology to help improve additive manufacturing. This kind of innovation is heading on the path to essentially allowing anyone to be a manufacturer,” said Arman Sabbaghi, an assistant professor of statistics in Purdue’s College of Science.

“This has applications for many industries, such as aerospace, where exact geometric dimensions are crucial to ensure reliability and safety. This has been the first time where I’ve been able to see my statistical work really make a difference and it’s the most incredible feeling in the world.”

Both 3D Printing and AI are very “hot” right now. Outside of the hype there are many ways that machine learning could be very beneficial for 3D printing in coming years in part prediction, melt pool monitoring and prediction, fault analysis and in layer QA. Purdue’s technology could be a possible step forward to “Intelligent CAD” that does much of the calculation, analysis and part generation for you.

Additive Industries has announced the finalists for its Additive World Design for Additive Manufacturing Challenge, a yearly competition where contestants redesign an existing, conventionally manufactured part of a machine or product with 3D printing, taking care to use the technology’s unique design capabilities, like custom elements and thin walls. This year, over 121 students and professionals entered the contest, and three finalists were chosen in each category, with two honorable mentions – the Unibody Hydraulic System by from Italy’s Aidro Hydraulics & 3D Printing and the Contirod-Düse from Nina Uppenkam, SMS Group GmbH – in the professional category.

“The redesigns submitted from all over the world and across different fields like automotive, aerospace, medical, tooling, and high tech, demonstrated how product designs can be improved when the freedom of additive manufacturing is applied,” said Daan Kersten, CEO of Additive Industries. “This year again we saw major focus on the elimination of conventional manufacturing difficulties, minimization of assembly and lowering logistical costs. There are also interesting potential business cases within both categories.”

The finalist designs are listed below, and can be seen in the image above, left to right, top to bottom:

  • “Hyper-performance suspension upright” from Revannth Narmatha Murugesan, Carbon Performance Limited (United Kingdom, professional)
  • “Cutting dough knife” from Jaap Bulsink, K3D (The Netherlands, professional)
  • “Cold Finger” from Kartheek Raghu, Wipro3D (India, professional)
  • “Brake Caliper” from Nanyang Technological University team (Singapore, student)
  • “Cubesat Propellant Tank” from Abraham Mathew, the McMaster University (Canada, student)
  • “Twin Spark Connecting Rod” from Obasogie Okpamen, the Landmark University (Nigeria, student)

To save time by moving past the lengthy requisitioning process, 3D printing was used at Marine Corps Base Hawaii, Kaneohe Bay, to create a repair part that would help fix a critical component to increase unit readiness. This winter, Support Company, Combat Logistics Battalion (CLB) 3 fabricated the part for the Electronic Maintenance (EM) Platoon, 3rd Radion Battalion, and both EM technicians and members of CLB-3 worked together to design, develop, and 3D print the part, then repaired the component, within just one month, after having spent almost a year trying to get around delays to fix it.

US Marine Cpl. Anthony Farrington, designer, CLB-3, said that it took about three hours to design the replacement part prototype, and an average between five to six hours to 3D print it, before it was used to restore the unit to full capability.

“With the use of 3D printing, Marines are empowered to create solutions to immediate and imminent challenges through additive manufacturing innovation,” said subject matter expert US Marine Chief Warrant Officer 3 Waldo Buitrago, CLB-3.

“We need to embrace 3D printing and encourage our Marines to express their creativity, which in turn, could lead to solutions in garrison and combat such as in this case study.”

3D Printed Helicopter Blade Mold

Thermwood and Bell recently worked together to create a 3D printed tool, but not just any 3D printed tool. Thermwood believes that the 3D printed helicopter blade mold is the largest ever 3D printed autoclave-capable tool. Bell, frustrated with expensive tooling that took a long lead time, reached out to Thermwood for help, and the company suggested its LSAM system, with new 60 mm melt core technology. Bell then provided Thermwood with a 20-foot-long, 17-inch-high, 14-inch-wide closed cavity blade mold, and upon receiving both the model and Bell’s tooling requirements, Thermwood began printing the tool with Techmer PM’s 25% carbon fiber reinforced PESU material (formulated specifically for its LSAM additive printing) in a continuous run. The new melt core can achieve a high print rate, even when processing high temperature material, which was great news for Bell.

Glenn Isbell, Vice President of Rapid Prototyping and Manufacturing Innovation at Bell, said, “Thermwood’s aggressive approach to pushing the boundaries and limitations of traditional 3D printing and machining is exactly what we were looking for.”

The final bond tool was able to maintain the vacuum standards required by Bell for autoclave processing right off the printer, without needing a seal coating. Thermwood will soon 3D print the second half of the blade mold, and both teams will complete further testing on PESU 3D printed molds for the purpose of continued innovation.

Interview With Valuechain on ERP and MRP for Additive Manufacturing

3D printing is still for many companies something that is divorced from regular business processes. Somewhere in a ventilated room a few printers hum and prototypes are taken out of them every once in a while. Meanwhile, in businesses that use 3D printing for manufacturing, 3D printing software controls, logs and verifies builds is being implemented. In large enterprises, systems integrators and IT departments now have to find a way to tie 3D printing production to internal systems such as ERP and PLM. Early on, I was once sitting next to a nice man on a plane who warned me to never ever get involved with an ERP implementation. Ignoring his advice, a few years later I found out it’s like trying to cram your whole company on an Excel sheet while an external vendor sells you the most expensive thing ever without anyone understanding what it does and how to use it. Its kind of like a super complex corporate Kinder Egg toy but you never manage to assemble it and instead of tossing it you’re stuck with it forever and now only Mary knows how to get more Post Its. I’ve always seen it as either multivitamins for corporations or one of those magnet therapy wristbands for companies. Either once you’re old an wise enough you start doing it because its smart to do so or its a special kind of hokum that some believe in fervently while the majority of people ignore its existence. Somewhere between that experimental department in the office and 3D printing for manufacturing ERP, CRM and all the IT tooling in your firm will meet, however. And its going to suck. Systems integration companies will do well trying to knit together the improvised processes we have with the established ways of managing a company. Being involved in this process and being a player that could extricate firms from this mess would be a good play indeed. More and more grafting 3D printing onto a firm will be a fast growing business. This is why 3DPrint.com reached out to Jim Walters, MD of DNA ltd. to talk about Valuechain a company that purports to have a way to do just that.
What is Valuechain?
“Valuechain Technologies is a global enterprise software business which provides modular ERP solutions for advanced manufacturing sectors, and supply chain intelligence solutions. Focusing on niche processes such as additive manufacturing, Valuechain’s modular ERP integrates CRM, compliance auditing, data capture, advanced reporting, NPI and supplier portals to digital business processes to improve productivity. Valuechain’s supply chain intelligence applications include supply chain performance management, multi-tier supply chain mapping, and supplier / customer portals. Designed by Valuechain’s leadership team, with over 100 years’ experience owning and running advanced manufacturing companies, Valuechain’s solutions are developed in collaboration with our 500+ SME clients and leading manufacturing companies including Airbus, Bentley Motors and Rolls-Royce, to provide scalable solutions for companies of all sizes.”
Do you believe in the Digital Twin concept?
“The ability to visualise products and processes in a virtual environment can reduce waste significantly by accelerating technical problem solving and knowledge transfer through lower risk prototypes and simulated pilots. This compresses new product introduction and enables businesses to engage stakeholders prior to major investments in people, product, plant, processes and systems which not only mitigates risk but also reduces quality non-conformances, costs and drives on-time in full delivery.”
How would I digitize my entire manufacturing process?
“The priority must be to create capacity for change which for many companies is about streamlining data capture and removing waste caused by fragmented systems and processes. It is important to understand current performance measures and prioritise improvement areas with tangible success criteria. Through digital production control, work flow and business intelligence solutions such as Valuechain’s solutions it is then possible to do more with less and operate smarter by providing key personnel with reliable business intelligence to make informed decisions. Too many businesses focus on historic KPIs ie. what happened, rather than focusing on why things are happening and what is likely to happen, it is therefore critical to capture diagnostic analytics to capture risks and lessons learned to embed corporate learning that can underpin AI driven predictive analytics.”
What kind of Additive Manufacturing software do you have?
“We have either a complete end to end MRP solution including our AM TRACE module, which will handle the whole of life production and sub con / post processes operations from estimating through to invoice or alternatively the AM TRACE module is available as a bolt on “app” for existing and legacy MRP ERP or MES solutions. We also currently have two versions of this, AeroDNAam DNAam and new this year is our DNAam Start-Up Program to assist smaller SME companies enter the AM sector.”
For what industries is DNAam meant?
“DNAam was designed for AS9100 Aerospace manufacturing initially but since its launch at Paris Air Show in 2017 with the backing of our first clients and innovation partners AIRBUS and Zenith Tecnica in New Zealand. However not surprisingly the unique and dynamic TRACE solution for materials and consumables associated with the manufacturing process has attracted interest from the Medical Automotive and Heavy industries also such as shipbuilding along with Oil & Gas. That will only continue to grow for us.:
How does this optimize build planning?
“We have 2 levels of capacity planning / scheduling – which can show machine availability + planning control.”
Do you optimize nesting as well?
“DNAam manages the production process for AM parts, and integrates with software for design which may optimise nesting.”
Is this meant only for powder bed fusion operators?
“Initially, DNAam was developed for EBM production, however, over the last year we have expanded its capabilities to work with a variety of technologies, including FDM, Laser, SLS, WAAM, Polyjet… pretty much anything.”
Why is traceability so important?
“Highly regulated sectors such as aerospace and automotive require end-to-end traceability to ensure accountability for compliance throughout the product lifecycle. Additive manufacturing offers significant opportunities to optimise raw material usage but only if unused powders and materials can be recycled. However scaling up traceability for all recycled and blended AM material batches has prior to DNAam has been complex, manual and prone to human error.”
What unique features do you have?
Visual Stock management tool: DNAam’s visual stock location management Drag and drop Gins between locations as they progress along the production process, from Goods In to Powder Storage, to Machining to Blend area. Any time you move a Gin, a record is automatically recorded of who moved what, when, and to where; so you have complete audit traceability.
  • Configurable chemical elements for each material , to store sample results.
  • Graded material control.
  • Detail production data capture forms (iQapture)
  • Visual AM-Trace tool: Two major challenges of implementing AM parts in aviation are traceability of the powder and achieving repeatability in the process to standardise it. The trace tool allows us visualise every build in which a batch of powder has been used by clicking on it. This intuitive tool provides complete traceability which can be used to scale-up AM production, not only in aerospace but in all types of industries.
Why should I buy this?
“DNAam has been innovated in collaboration with some of the world’s leading advanced manufacturing companies such as Airbus, to embed best practice, scalable AM business processes and capture AM business intelligence. As a modular solution DNA.am can work alongside existing ERP solutions for primes and tier 1’s, or as a cost-effective turnkey ERP system from quotation through to invoicing for smaller AM businesses or even start-up AM bureaus.”

Researchers Use AI, 3D Printing & Bending Light for Numerical Calculations

Today, you will find 3D printers in the most surprising places—and all over the world. Not only that, but they are often busy doing the most surprising things for the human race. If you have been following 3D printing for even the shortest amount of time, then you may have learned to continually expect the unexpected. Machine learning and data calculations are perfect examples of this as they are now being applied in 3D via a new artificial intelligence system that performs its work through bending light.

AI is built on looping calculations of numbers and data that ultimately result in recognition. As UCLA researchers discovered, they can actually translate this into physical form through 3D printing with the accompaniment of light. Working with the premise of 3D printing that is built on layers, the researchers are able to make transparent diffraction patterns, ‘reflecting’ data in a neural network. Their work was recently published in a paper titled ‘All-optical machine learning using diffractive deep neural networks,’ by Xing Lin, Yair Rivenson, Nezih T. Yardimci, Muhammed Veli, Yi Luo, Mona Jarrahi, and Aydogan Ozcan.

“Deep learning has been transforming our ability to execute advanced inference tasks using computers,” state the researchers in their abstract.

They are able to establish this with a diffractive deep neural network, also known as a D2NN architecture—and one that is able to perform functions based on the collective diffractive layers.

“We create 3D-printed D2NNs that implement classification of images of handwritten digits and fashion products as well as the function of an imaging lens at terahertz spectrum,” state the researchers. “Our all-optical deep learning framework can perform, at the speed of light, various complex functions that computer-based neural networks can implement, and will find applications in all-optical image analysis, feature detection and object classification, also enabling new camera designs and optical components that perform unique tasks using D2NNs.”

The team used their unique learning model to recognize numbers that were written out by hand, afterward converting the matrix math into a data series related to ‘optical transformations.’ Each layer contributes to creating this data with the use of light, refocusing and adding values. This process involves millions of optical transformations on the 3D printed plates, with the system translating light into numeric values; in fact, the researchers report that with the 3D-printed D2NNs they are having a 90 percent success rate!

While the process is still being refined by the research team, it could be relevant to numerous applications in the future due to the flexibility of such calculation tools. It could be used to read letters instead of numbers too, as well as offering facial or other types of physical recognition.

3D Printing News Briefs: July 17, 2018

In Today’s 3D Printing News Briefs, we’re covering a lot of business and a little medical news. AMFG is partnering with a top UK bearings manufacturer to help automate its digital manufacturing workflows, while Segula Technologies has begun an industrial 3D printing partnership with digital manufacturing company Multistation. Techniplas has completed a deployment of Sharebot 3D printers to its 14 manufacturing facilities around the world, and the winners of the SkillsUSA Additive Manufacturing Competition have been announced. Finally, a pediatric cardiologist used the Sinterit Lisa to create a 3D printed model of a newborn boy’s heart to plan his risky surgery.

Bowman International Announces Partnership with AMFG

Bowman’s bearings

Automation software specialist AMFG, which recently launched a new AI software platform, has partnered with Bowman International, one of the top bearings manufacturers in the UK, as it works to grow its 3D printing capabilities through its Bowman Additive Production (AP) division. Bowman AP has several MJF and SLS 3D printers available for its use, and uses 3D printing to design and produce its end-part bearings, which has helped increase their load bearing capacity by up to 70%.

In the meantime, Bowman International’s goal is to use AMFG’s AI-powered production automation software to oversee production of said bearings, by automating production job scheduling, optimizing digital CAD files for production with printability analyses, and creating a custom digital part catalog.

“We’re very pleased to be partnering with AMFG and using their automation software to scale our already expanding AM facility,” said Jacob Turner, the Head of Additive Production at Bowman International. “Additive manufacturing is transforming the way bearings are manufactured, and we aim to continue to be at the forefront of innovating the production of bearings using AM. AMFG’s automation software will enable us to achieve this by significantly increasing the efficiency of our production processes.”

Multistation Partners with Segula Technologies

Another newly announced 3D printing partnership is the one between international engineering group Segula Technologies and Paris-based 3D printing company Multistation. The two are working together to further develop the potential of 3D printing in the industrial sector, which will allow both companies to increase their offerings and provide customers with excellent services along the AM value chain. Segula will bring its design, product-process qualification, and technology integration in industrial environments to the table, while Multistation will share and apply its expertise in AM design and simulation by determining any potential parts that could be 3D printed instead of fabricated with a more traditional method of manufacturing.

“Additive manufacturing is an integral part of a value chain within which Multistation provides a comprehensive offering; Segula Technologies was an obvious partner of choice to enable our Additive Consulting division to address manufacturers’ concerns more effectively,” said Yannick Loisance, the CEO of Multistation. “We will thus be able to supply them not just with software packages, machines and materials, but also with a more comprehensive range of high-quality engineering services that are suited to a host of different business sectors.”

Techniplas Adds Sharebot 3D Printers to Its Manufacturing Facilities

This fall, Italian professional-grade 3D printer manufacturer Sharebot joined the open innovation program at Techniplas, a top automotive design and manufacturing provider. Now, as part of its own continuing digital transformation, Techniplas has deployed Sharebot 3D printers to all of its 14 manufacturing facilities across five continents. This move will allow the company to 3D print the majority of the manufacturing products it uses every day on-site, which will equal major cost and time savings as Techniplas previously used only third-party providers for this task.

“With Sharebot 3D printers installed in all of our manufacturing facilities worldwide, we are taking decisive steps toward fabricating the majority of our manufacturing line assembly tools, jigs, fixtures, gauges and even robotic arm attachments in-house. Based on our experience with Sharebot printers thus far, we expect to significantly reduce our development time and annual assembly line tooling costs in each manufacturing facility over time,” said Techniplas COO Manfred Kwade.

Surgeon 3D Prints Pediatric Heart Model with Sinterit Lisa

Desktop SLS 3D printer manufacturing Sinterit has seen its flagship Lisa 3D printer, which went through a recent upgrade, used to save lives in multiple ways, from fighting wildfires and protecting the faces of children to providing assistance in a tough pediatric cardiac surgery.

“Delivering desktop SLS 3D printer for more than three years caused that our clients send us tonnes of useful and exciting cases. Writing about all of them is hard, if not impossible, but when 3D printing helps saving lives, especially those most fragile, we feel proud, and also a duty to share it with you,” Michał Krzak, Sinterit’s Marketing Communication Manager, told 3DPrint.com.

A newborn’s heart can weigh barely 20 grams, and fits in the palm of an adult’s hand, so you can imagine that surgeries on such a delicate organ are exceedingly difficult. Jarosław Meyer-Szary, MD, from the Department of Pediatric Cardiology and Congenital Heart Defects at the University Clinical Center in Poland recently turned to Sinterit’s Lisa 3D printer to save the life of Kordian, an infant less than one month old suffering from a potentially fatal heart disease called interrupted aortic arch.

Meyer-Szary created 3D printed, life-size model of Kordian’s tiny heart, and SLS technology was able to recreate each intricate artery and vein. The model not only helped him plan the surgery ahead of time, but also helped Kordian’s mother gain a more thorough understanding of her son’s condition. Kordian is now a thriving and happy 18 month-old, thanks to Sinterit’s SLS technology.

3D Printing News Briefs: June 26, 2018

We have plenty of business, material, and 3D printer news to share with you in today’s 3D Printing News Briefs. 3D printing led to increased savings for GM over the last two years, which is now increasing its use of the technology as a result. ExOne is saying goodbye to one CEO and hello to another, while Polymaker announces a global distribution arrangement with Nexeo Solutions and CollPlant receives R&D project approval in Israel. The US Patent and Trademark Office will be hosting its annual Additive Manufacturing Partnership Meeting this week, and RP Platform has announced a rebrand and a new AI software platform. Finally, the UK’s National Centre for Additive Manufacturing has decided to add Digital Metal’s binder jetting technology to its portfolio.

GM Increasing Use of 3D Printing at Plants

According to Dan Grieshaber, the Director of Global Manufacturing Integration for General Motors (GM), most of the company’s factories have 3D printers, which are used to build accessories and tools for workers. A $35,000 3D printer at GM’s Lansing Delta Township assembly plant has actually helped save the company over $300,000 over two years: it’s used to make multiple items, such as part hangers, socket covers, and ergonomic and safety tools. A common tool used to align engine and transmission vehicle identification numbers cost $3,000 to buy from a third party, but is less than $3 to 3D print at the factory. Realizing that these kinds of savings can add up quickly, GM is increasing the use of 3D printing – part of its new Manufacturing 4.0 processes – at its plants in order to help streamline operations.

“We’re quickly evolving, creating real value for the plant. This will become, as we progress, our footprint. We’ll have this in every one of our sites,” Grieshaber said.

Grieshaber also said that GM is working to standardize 3D printing, as well as share best practices across all of its global plants.

ExOne Welcomes New CEO

The ExOne Company, which provides 3D printers and 3D printed products, materials, and services to its industrial customers around the world, has announced that its CEO, James L. McCarley, is departing the company, effective immediately, to pursue other interests and opportunities; he will be assisting the company in transitioning his responsibilities to the new CEO. ExOne’s Board of Directors has also announced who the new CEO will be – S. Kent Rockwell, the company’s Executive Chairman, who has served in the position in previous years. Rockwell’s new title is effective immediately.

“On behalf of our Board and management team, I would like to thank Jim for his efforts and wish him all the best in his future endeavors,” said Rockwell.

Polymaker Makes Distribution Arrangement with Nexeo Solutions

Shanghai-based 3D printing material producer Polymaker has entered an arrangement with chemicals and plastics distributor Nexeo Solutions, Inc., also based in Shanghai. Nexeo will be a global distributor for three new materials in the Polymaker Industrial line, but plans to introduce more of its materials over the rest of the year. C515 is an advanced polycarbonate (PC) filament that has excellent toughness and a low warping effect, while C515FR is a flame retardant PC with high impact resistance. SU301 is a polyvinyl alcohol (PVA)-based polymer that’s water soluble and was developed as a support material for FFF 3D printers.

Paul Tayler, the Vice President of EMEA at Nexeo Solutions, said, “Expanding our portfolio to include industrial grade filaments from Polymaker Industrial gives our customers access to a wider range of filaments that solve new 3D printing challenges and meet the demands of manufacturers. Industrial customers benefit from Nexeo Solutions’ access to world leading plastic producers coupled with additive manufacturing technical expertise.”

CollPlant Receives R&D Project Approval

Two years ago, regenerative medicine company CollPlant received funding from Israel’s Ministry of Economy for its research in developing collagen-based bioinks for 3D printing tissues and organs. CollPlant, which uses its proprietary plant-based rhCollagen (recombinant human collagen) technology for tissue repair products, has now announced that the Israel Innovation Authority (IIA) has approved a grant to finance the continued development of its rhCollagen-based formulations intended for use as bioinks. Terms of the grant require CollPlant to pay royalties to the IIA on future sales of any technology that’s developed with the use of the funding, up to the full grant amount. The total project budget is roughly $1.2 million (NIS 4.2 million), and the IIA will finance 30%, subject to certain conditions.

“In addition to providing immediate non-dilutive funding, this grant from the Israel Innovation Authority represents an important validation of our BioInk technology and its market potential. With the recent opening of our new cGMP production facility in Rehovot, Israel, we are well positioned to meet growing demand for our BioInk and tissue repair products. We are grateful to the IIA for this recognition,” said CollPlant CEO Yehiel Tal.

Additive Manufacturing Partnership Meeting Hosted by US Patent and Trademark Office

For the last several years, the US Patent and Trademark Office (USPTO) has been hosting the Additive Manufacturing Partnership Meeting, and this year’s meeting takes place tomorrow, June 27th, from 1 to 5 PM at the USPTO headquarters inside the Madison Building in Alexandria, Virginia. The USPTO will be seeking opinions from various participants at the informal meeting, which is really a forum for individual 3D printing users and the USPTO to share ideas, insights, and personal experiences.

“We value our customers and the feedback provided from individual participants is important in our efforts to continuously improve the quality of our products and services,” the USPTO meeting site reads. “Your willing participation in this informal process is helpful in providing us with new insights and perspectives.”

Scheduled speakers at this year’s meeting are coming from CIMP-3D, HRL, Kansas State University, Lawrence Livermore Laboratories, and the NextManufacturing Center, and an RSVP is required to attend the AM Partnership Meeting.

RP Platform Launches New AI Software and Rebrand

London-based RP Platform, which provides customizable workflow automation software for industrial 3D printing, is launching a new software platform, which will use AI for the first time to automate 3D printing production. With customers in over 30 countries, the company is one of the top automation software providers for industrial 3D printing. In addition to its software launch, RP Platform has also announced that, as it continues to expand its software capabilities to target AM end part production, it is rebranding, and has changed its name to AMFG.

“We want to help companies make their 3D printing processes much smoother so that they can produce more parts with greater visibility and less effort. And we have more exciting releases to our software over the coming months that will further enhance our production automation capabilities,” said Keyvan Karimi, the CEO of AMFG.

“Ultimately, we’re creating a truly autonomous manufacturing process for industrial 3D printing. For us, this means taking manufacturing to a new era of production. The launch of our new software, as well as our company rebrand, fully reflects this vision going forward.”

NCAM Installing a Digital Metal 3D Printer

The National Centre for Additive Manufacturing (NCAM) in the UK, headquartered at the Manufacturing Technology Centre (MTC) in Coventry, has decided to add the unique binder jetting technology developed by Digital Metal to its large range of advanced manufacturing equipment, and will soon be installing one of its high-precision metal 3D printers – which are not available anywhere else in the UK. The 3D printer will be available for use by NCAM’s member companies, and other organizations, who are interested in testing the capabilities of Digital Metal’s proprietary binder jetting technology.

Dr. David Brackett, AM Technology Manager at the NCAM, explained, “The Digital Metal binder jetting technology falls into the category of ‘bind-and-sinter AM’, where a multi-stage process chain incorporating sintering is required to achieve full density. It’s a very fast technology that can create complicated and highly detailed designs, and there is potential for wider material choice than with AM processes that use melting. We are delighted to be able to offer this to the companies we work with.”

The Digital Metal 3D printer will be operational later this summer, and NCAM personnel are already training with it to ensure they can operate it efficiently and safely.
