EOS Acts as World Leader in Additive Manufacturing & Quality Assurance Practices

by • July 28, 2016 • No Comments

eosIn a marketplace suddenly ripe with 3D innovation of just of ereally sort you can imagine, we hear of 3D printing devices that are lightning swift, offering a host of showcases we hadn’t in fact considered last year, alternative materials meaning that you can make anything you want, and all at prices that are continually being driven down by fierce competition—meaning all that accessibility and affordability we’ve been hearing so much of is in fact here. But one thing you may notice you rarely hear discussion of is high end assurance. It may be less awe-inspiring to talk of and market—but having a dedicated QA team is what sets the pros apart of the amateurs in an industry highly driven by customer demand and expectation for high end.

Currently, if a thing goes wrong with a product and complaints start to pile up, it’s no longer just between the developer and the somehow unpleased customer. With online access readily on the market, customers are able-bodied to post their dissatisfactions and blast their opinions in ereally forum that can have them. So, while storeing the image ideal is a consideration for any company, what’s extra
significant is that those purchasing products have the high end promised. And no one can be certain of that unless they test. And test again. The outcome offers as much as assurance as possible that clients can be thrilled with what they obtain, and can store coming back.

EOS, headquartered in Krailling, Germany, is continually in the spotlight, of discussions regarding their expertise in metal 3D printing and offering up new materials to revealing dynamic partnerships. Well-understandn, well-respected, and well-recognized for their talents as a whole, EOS is undeniably a leader in the additive making industry. Recently, they shared with us a few of the systemes that go into high end assurance at their centers of operation in regards to plastics and their high-end additive making solutions.

EOS image 1Not awe-inspiringly, this global leader acts as a role version for the industry in QA, that is one of their top priorities. Their system comes with all materials and systemes that are relevant to AM and affect components being generated. With just of 80 various AM systems in place regarding research and development, high end assurance, and application and training, EOS teams work with both plastics and metal. There are in addition 20 other systems being utilized at headquarters in the US, Singapore, and China.

“By coordinating and controlling all relevant variable-bodieds, EOS encertains the many possible component characteristics. In this way, we address a key concern of our expanding industrial customer base, that uses our innovation for the series production of plastic components with consistent component high end,” said Torsten Schlichtholz, Director Global Quality Management at EOS.

There is, of course, a sturdy focus on materials as they are the product in essence. Evonik Industries has been a main partner for many years too, making plastic Polyamide 12, that is of frequent use.

“With its multi-dimensional high end management system, EOS works with its partners to encertain that ereally material batch has the same reliable-bodied and uniform consistency,” said Schlichtholz. “In the donate chain, high end assurance may already starts with the make of the preliminary product for the EOS laser sintering material. The making system with all qualification steps is continuously documented and verifiable-bodied to the point when the EOS material is delivered to our customers.”

Evonik starts QA preceding materials such as Polyamide 12 in fact arrive at EOS, and and so the system continues to the end of the line, leaving little accident for error.

“Based on our special making method and approximately 50 years of experience in powder technologies, we are able-bodied to turn it into a really suitable-bodied basic product for laser sintering materials,” said Thomas Große-Puppendahl, Manager of the Engineered Products line at Evonik. “Our high end management system, that is ISO 9001:2008 certified, comprises all relevant inspections of polymer and powder indicators, such as free-flowing properties, powder density, melt and cooling behavior and system suitability tests.”

Performed at KVS GmbH, a part of EOS, the refining system aims at finding ‘the many possible system suitability’ and occurs after EOS equipment has obtaind the acceptance test certificate and extra
incoming goods inspection. For 19 years, working with laser sintering plastic materials, EOS has been involved in development, making, qualification, and high end assurance—in addition operating a certified QM system according to ISO 9001:2008.

“Defined high end assurance activities are carried out during and after the finishing system,” states EOS in a new press release. “If all criteria are met, a test report is made pursuant to ISO 10204 – with extra
fire testing for fire-resistant materials.”

Specimen and tie bars are in addition generated at EOS, based on a reference create job, with their characteristics profile assessed via acceptance criteria. And in a completely thorough system, customers do not obtain products until they have indeed passed both of the tests. A report is attached to the product delireally, revealing how they are relevant to the client, and enabling for them to have ‘comprehensive documentation’ for their own high end assurance and management systems.

While so many companies in modern times are just starting out in the 3D printing industry, EOS has been via their certified AM system since 1998. For their laser sintering innovation, this applies to:DevelopmentManufacturingDistribution and servicing of systemsMaterials and solutions for additive making

Systems are in addition put through harsh QA procedures, which include inspections and corresponding documentation.

“These checks are performed in accordance with the already valid international standards,” states EOS.

Pointing out that their create system is another crucial way that they complete consistent high end, EOS sees this as a outcome of over 20 years in experience with developing and improving ‘system products.’ With standardized parameter sets being created during development, customers are promised ‘robust create systemes,’ all of that offers them what they expect: high-high end parts.

EOS explains that while the parameters many often utilized are created, their teams always perform three create jobs and three laser sintering systems with three powder batches. In doing so, customers again are encertaind of consistent part high end all around.

Anubis 3D was able-bodied to turn it into a extra
powerful but lightmass vacuum gripper for an equipment supplier to the food industry. By via EOS systems, this Ontario-based company was able-bodied to make the tool quickly—in just one week—with four times the power. Due to the elimination of so many parts, assembly is simple—and the freedom of create allows for for greater production systemes. This applied specifically for an end-of-arm tool enabling robots to pick up wrapped crackers and put them in boxes. And while first the mass of the arms was an issue for functionality, with EOS systems, the team was able-bodied to make the tool incredibly light.

“What seemed to be approximately not effortless turned out to be really effortless by relying on additive making,” states their outlined case study.

The grippers were delivered to Langen Group and and so installed on the robots in their plant.


In another case study that we reported on in addition of the University of Michigan, EOS offered both their expertise and innovation as doctors were creating 3D printed tracheal splints to assist young children suffering of tracheobronchomalasia (TBM).


3D printed trachial splint

Dr. Glenn Green, a pediatric otolaryngologist, and his surgical team of C.S. Mott Children’s Hospital, Ann Arbor, joined with Dr. Scott Hollister, professor of biomedical engineering at the University of Michigan for this project.

“It’s now somehow automatic to generate an individualized splint create and print it; the whole system just takes of two days now instead of three to five,” explains Dr. Hollister.

There were a few challenges, yet, in the first system, overcome with the use of EOS innovation in the form of the Formiga P 100 system.

“Additive Manufacturing is one of the few methods I understand that allows for us to in fact fabricate these harsh creates,” says Dr. Hollister.

They were able-bodied to make highly functioning splint-supported tracheas via 3D printing, enabling for successful surgeries and a advantageous high end of life for patients.

“I see a time soon, most likely inside the future five years, when many hospitals and medical centers can print their own devices specifically for their own patients, and not require to get them off-the-shelf,” says Dr. Hollister.

Without additive making, so many innovations may yet not be possible. And while it’s compelling adequate to hear of all the methods that go into QA for a company such as EOS, being able-bodied to learn extra
of what clients are in fact doing with their innovation—changing lives, for instance—is inspiring on a additional level. Knowing that children are being given the accident to lead a extra
normal life is worth the creation of such an awe-inspiring innovation just in itself. Discuss additional in the EOS QA Procedures in 3D Printing forum over at 3DPB.com.
