Third Munich Technology Conference: A reality check on additive manufacturing industrialization

The Third Munich Technology Conference (MTC3) returned to the Technical University of Munich (TUM) yesterday with a quest to evaluate the status of additive manufacturing industrialization.  Despite the gloomy weather, over 1500 attendees are present, including 3D Printing Industry, for the three-day event which seeks to give a “Reality Check” to those adopting additive manufacturing […]

Additive Manufacturing Open Cluster in Bavaria: TUM, Oerlikon, GE Additive & Linde Collaborate

Several heavy hitters on the international additive manufacturing scene have come together to form a research cluster. With the goal of researching AM processes from one location, a ‘single hub,’ The Technical University of Munich (TUM), Oerlikon, GE Additive and Linde are collaborating on how to integrate AM into manufacturing processes and help companies transition to the use of newer technology.

Designated as an ‘open cluster,’ the collaboration will include numerous universities responsible not only for researching AM but also teaching. Regulatory authorities are also involved in the cluster, as they continue to perform oversight and regulation regarding industry technologies. The collaboration will be open to expansion with new participants as time goes on.

“By having all of the players located in a single hub, we are accelerating the development and application of the technology for the various industries,” commented Professor Dr. Michael Suess, Chairman of the Board of Directors of the Oerlikon Group, in a recent press release sent to “Bavaria is the perfect place for us to house this initiative as it promotes energy and production efficiency, which supports Germany’s sustainability goals and the country’s desire to incorporate new technologies.”

Signing Letter of Intent in Dec. 2018.

Organizations such as TUM, Oerlikon, GE Additive and Linde are highly invested in the transformative powers of AM, as well as helping companies adjust to the accompanying changes to the following:

  • Supply chain
  • Production
  • Employee training
  • Quality inspection
  • Product validation
  • Regulation

 “The project is an excellent example of close collaboration between industry, academia and politics to innovate and industrialize a technology like additive manufacturing,” commented Dr. Roland Fischer, CEO of the Oerlikon Group. “AM is a technology that supports our aim of providing sustainable solutions for all industries.”

The group has chosen a progressive locale for their work in AM:

“Bavaria already enjoys a stellar reputation as a global hotspot for additive technology – with a thriving ecosystem and a rich seam of talent,” said Jason Oliver, President and CEO of GE Additive. “We’re excited to be part of this initiative from the very beginning and look forward to building on that solid foundation and driving tangible impact both for the region itself and further afield.”

One of the initial steps taken on by the research cluster will be the opening of The Additive Manufacturing Institute, a site dedicated to:

  • Interdisciplinary research in raw material powders
  • Optimized AM production
  • End-to-end process integration (plus automation and AM digitalization)

As they continue to offer a comprehensive program regarding AM research and operating procedures, Oerlikon will be sending both engineers and scientists to TUM faculties—also assisting in verification and qualification of product development.

“We see this opportunity to collaborate as a win for the companies and TUM, as well as for the region,” said Dr. Christian Bruch, Member of the Executive Board, CEO of Linde Engineering. “We expect the new hub will bring jobs to the area, while also delivering new technologies and capabilities to the companies located here.

The institute will be open to other companies and universities also, but not until after the initial foundation is set, with frameworks established. Projects such as this are an extension for companies like GE Additive, already heavily involved in offering innovation such as development of new combat vehicles, new materials like metal powders, magnetic components, and much more.

“An integrated collaboration between powerful partners from industry and science is necessary for the industrialization of additive manufacturing processes,” said Professor Dr. Thomas Hofmann, President of TUM. “This is the only way we will be able to overcome technological obstacles and find answers to unresolved issues in the field of standardization.”

The new additive manufacturing cluster and research institute are being highlighted at the Munich Technology Conference (MTC3), which is currently taking place at the Technical University of Munich in Germany (October 8-10, 2019). The conference this year addresses the industrialization of additive manufacturing and features top speakers from the industry, academia and political sectors.

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.

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.

For Linde, Additive Manufacturing is a Gas

Additive manufacturing, particularly metal additive manufacturing, involves a lot more than just some powder and a 3D printer. There’s also a lot of gas involved, and that’s what industrial gas giant Linde realized in 2016. The company recognized an opportunity to develop gas application potential across the entire additive manufacturing process chain.

Christoph Laumen

“It starts in the powder atomization, through the actual printing or building process, and goes further to all the post-treatment operations,” said Christoph Laumen, whose team is developing Linde’s additive manufacturing solutions.

Linde has been working with partners like the Airbus Group and has seen the potential for gas to play an invisible yet important role in the additive manufacturing process. Linde was the first company to recognize that it could contribute to influencing additive manufacturing materials’ properties by using active gases and a variety of flow characteristics. According to Laumen, the company’s initial focus was on creating a solution that would give customers greater ability “to measure and control the oxygen content and humidity in the powder beds of the print chamber.” This was key in achieving reproducible results and led to the launch of the ADDvance line of additive manufacturing solutions.

“We have a competence that very few people in this ecosystem have,” Laumen continued.

In 2016, Linde opened its Linde Global Development Center on Additive Manufacturing and began what Laumen called “a development roadmap for the next three to five years, with more than 30 project ideas that will really make a difference to the industry.”

“Some are really visionary,” he said. “It’s really the second and third generation of AM. But there are other things that can increase productivity and improve the traceability and reproducibility of the parts very short term.”

As its research has progressed, Linde has seen its role in additive manufacturing evolve, according to Laumen, “from satisfying customer demands to really having our own understanding where the technology will go, how it will evolve, and how our role can be going forward.”

“We’re really focusing on tailor-made gas mixtures for powder bed fusion and for all major alloy systems. So there is a focus on titanium and aluminum, the ones that are mostly used in the industry right now,” he continued. “But we are also looking into gas management, recirculation concepts, recycling systems. To make this technology for mass production, like the automotive industry and consumer goods, you really need to get the costs down. We want to make sure that the technology becomes affordable and gets more viable for a wider industry.”

Laumen estimates that 10 to 15 projects currently in progress will be ready for launch by 2025. Linde highly values collaboration and industry partnerships, which played a role in the company’s decision to become one of seven partners of the second Munich Technology Conference (MTC).

“Working with partners has a very long history at Linde, and this is always our preferred model,” Laumen said. “Only by involving partners and lead customers will you really understand the end user requirements. And often it improves agility and speed to market. The MTC event last year demonstrated that it has the potential to bring high-level deciders and influencers together. I personally also liked the open spirit very much, and the mutual strive for making AM something great and transformative. Linde has identified AM as one of the future growth areas, and we wanted to make sure that we are well positioned and contributing our fair share. And as partner in 2018, MTC2 gave us the opportunity to talk in more detail to people about what are their key influencing factors and challenges into today’s AM ecosystem – in fact in our workshop the collaboration with over 60 people was great, with people openly giving their insight to help improve the industrialization of AM for all going forward.”
