Perstorp AB creates 3D printer materials venture with 3D4Makers

Perstorp AB, a world leading specialty chemicals company, and 3D printing filament producer 3D4Makers have joined forces to create Netherlands based company ‘ElogioAM’ a new material production venture.

Combining the knowledge of chemicals and polymers, ElogioAM is introducing Facilan, a strong and compostable filament for FDM/FFF 3D printing. 

Stamping out common 3D printing issues

User reported issues detail problems with layer adhesion, warping, surface quality and misprints which limits printability of existing filaments. Perstorp AB and 3D4Makers designed Facilan fit-for-purpose filaments to remedy such issues through a wide range of medical and manufacturing products. The companies collaborated as a result of their shared ambition to create a new generation of materials for the 3D printing industry.

“It is all about chemistry and engineering at their best, and for satisfying today’s demand for more reliable FDM [Fused Deposition Modeling] 3D printing quality,” said David James, Vice President of Perstorp AB.

Comprised of three materials, the Facilan filaments are compostable bioplastic FDM grades that have a higher impact and tensile strength when compared to ABS filaments. Additionally, Facilan parts offer a smoother texture as opposed to PLA and ABS parts.

Modeling and Simulation of Functionalized Materials for Additive Manufacturing and 3D Printing: Continuous and Discrete Media: Continuum and Discrete … Notes in Applied and Computational Mechanics)

Within the last decade, several industrialized countries have stressed the importance of advanced manufacturing to their economies. Many of these plans have highlighted the development of additive manufacturing techniques, such as 3D printing which, as of 2018, are still in their infancy. The objective is to develop superior products, produced at lower overall operational costs. For these goals to be realized, a deep understanding of the essential ingredients comprising the materials involved in additive manufacturing is needed. The combination of rigorous material modeling theories, coupled with the dramatic increase of computational power can potentially play a significant role in the analysis, control, and design of many emerging additive manufacturing processes. Specialized materials and the precise design of their properties are key factors in the processes. Specifically, particle-functionalized materials play a central role in this field, in three main regimes:

 (1) to enhance overall filament-based material properties, by embedding particles within a binder, which is then passed through a heating element and the deposited onto a surface,

 (2) to “functionalize” inks by adding particles to freely flowing solvents forming a mixture, which is then deposited onto a surface and

 (3) to directly deposit particles, as dry powders, onto surfaces and then to heat them with a laser, e-beam or other external source, in order to fuse them into place.

The goal of these processes is primarily to build surface structures which are extremely difficult to construct using classical manufacturing methods. The objective of this monograph is introduce the readers to basic techniques which can allow them to rapidly develop and analyze particulate-based materials needed in such additive manufacturing processes. This monograph is broken into two main parts: “Continuum Method” (CM) approaches and “Discrete Element Method” (DEM) approaches. The materials associated with methods (1) and (2) are closely related types of continua (particles embedded in a continuous binder) and are treated using continuum approaches. The materials in method (3), which are of a discrete particulate character, are analyzed using discrete element methods.

US Navy Explores 3D Printing with Explosive Materials

alt L to R: Naseem Jibrin, Benjamin Ennis, Brandon Ennis and Michael Winn (UTC)

By MarEx 2018-04-16 20:24:00

A small consultancy in Chattanooga, Tennessee is helping the U.S. Navy turn explosives into custom shapes using commercial 3D printing techniques. The staff of E&G Associates – engineers Benjamin Ennis, Brandon Ennis, Nasseem Jibrin and Michael Winn, all graduates of the University of Tennessee – are working on ways to use an off-the-shelf Hewlett Packard 3D printer to create shaped charges. 

HP’s ink-and-thermoplastic powder bed fusion printers have been on the market since 2016, making them a relatively recent arrival (compared with more established 3D printing technologies like material extrusion or laser sintering). Hewlett Packard advertises them for low-cost, rapid prototyping and short-run parts manufacturing.

“The printer spreads the nylon powder and then prints on that flat layer of powder with the ink. Then the printer passes a heat lamp back and forth to make the dark areas melt. And that’s how you get your parts,” Jibrin told UTC’s alumni magazine. “The process is repeated in three steps. Spread a layer, ink the specific selected areas and fuse with heat lamps. You do that over and over again until you build a part.”

HP’s printers are not marketed for bomb-making, but with some careful R&D and a $150,000 federal grant from the Small Business Innovation Research program, the E&G team thinks that the platform can be adapted for military applications. The group is testing nylon powder infused with explosive material, polymer additives and printer ink to create its 3D explosive charges. 

E&G doesn’t have a blast chamber on site to test out the final product, but it has an agreement with the Missouri University of Science and Technology’s engineering department, which has all the equipment needed to detonate samples and study the results. “We’ll test in a chamber that’s basically a giant metal tube. It’s about eight feet high with inch-thick walls,” said Benjamin Ennis. 

E&G’s shaped-charge research is not the Navy’s first foray into 3D printing. Last year, the Oak Ridge National Laboratory worked with Surface Warfare Center Carderock to make a 30-foot submarine printed entirely of thermoplastic resin. The prototype was similar in size and function to the covert infiltration mini-subs used by the Navy SEALs, but Oak Ridge built its model much more quickly, and at a fraction of the normal construction cost. 

Oxford Performance Materials targets Asia after 3D printed medical devices approved in Japan

Mar 21, 2018 | By Benedict

Oxford Performance Materials, a company whose materials have been used in everything from medical implants to Boeing airplanes, has been given the green light to distribute its 3D printed medical devices in Japan, paving the way for major expansion within Asia.

Making a 3D printed medical implant—designing it, sourcing the right materials, performing the necessary medical testing—is no mean feat, but for some companies in the medical field, making such a device is actually only a small step on the road to commercialization. The trickiest part comes later.

That’s because, for a 3D printed medical device to have any value, it needs to be approved by governmental organizations. In the U.S., the FDA performs that role, examining individual products to see if they meet the necessary standards for use on human bodies.

To this end, the FDA recently published its guidance on 3D printing of medical products in order to tell manufacturers what it is looking for in a product.

Connecticut’s Oxford Performance Materials (OPM) is one company that has frequently found itself dealing with the FDA in order to bring its specially designed PEKK (poly-ether-ketone-ketone) medical implants to market. The company’s OsteoFab implants are some of the industry’s most popular, and OPM has had several different implants given 510(k) clearance by the FDA.

That’s the U.S., but what of other markets? While some countries are relatively skeptical of 3D printing and in no rush to approve products that might go wrong down the line, others are taking a different tact. In Korea, for example, Ministry of Food and Drug Safety has explored fast-track options for 3D printed medical devices in order to get the technology developed faster. It’s a risky tactic, of course, but one that can benefit the national economy.

Elsewhere in Asia, Japan remains an influential figure in the medical device market. A famous advocate of new technologies, Japan can massively boost a medical device company’s profile by rubber-stamping its products for medical use.

Fortunately for OPM, Japan’s Ministry of Health, Labour and Welfare has just granted the American company Accreditation of Foreign Medical Device Manufacturer, permitting it to bring its laser melting OsteoFab 3D printed medical device options to the prosperous Asian nation.

OsteoFab combines laser melting additive manufacturing technology with OPM’s proprietary OXPEKK material formulations to offer 3D printed PEKK medical implants for craniomaxillofacial (CMF), spine, and other emerging orthopedic and neurologic indications.

OPM says it has long identified Asia as an attractive market because of “demographic trends and a predictable regulatory and reimbursement environment.” The company also believes that Japanese healthcare companies have an appreciation for beneficial technologies.

“OPM started regular exploration of the Asian market 10 years ago in order to deeply understand the reimbursement environments, potential markets and commercialization opportunities,” said Scott DeFelice, Chief Executive Officer and Chairman of the Board of Oxford Performance Materials. “This accreditation allows OPM to start an export program to initiate market development and advance our Asian business.”
