Formnext 2022: Overview of 3D printing materials –


While additive construction is being deployed right now to help with a military conflict between India and China, the additive manufacturing (AM) industry is focusing on Germany. We’ll see how the numbers stack up after the event, but it feels like Formnext 2022 is the biggest trade show the AM industry has seen so far. To cover all the news from the conference currently taking place in Frankfurt, Germany, we have published several summaries dedicated to hardware, software, 3D printing materials and more. In this article, we will give a brief overview of material news to which we have not had the chance to devote entire articles.

Inkbit Titan Tough Epoxy 85

Inkjet 3D printing startup Inkbit has introduced a new material called Titan Tough Epoxy 85, intended to exhibit production-grade mechanical properties. In particular, Inkbit claims that the photopolymer exhibits high impact resistance and can withstand long-term UV exposure, issues faced by typical photopolymers in 3D printing. Inkbit is also showcasing its Vista 3D printer for the first time at Formnext.

Carbon EPU 43 and 45, Henkel Loctite IND147

Continuous digital light processing (DLP) pioneer Carbon introduces two new damping elastomers. The white EPU 43 is meant to be an energy-absorbing elastomer with durability under high-cycle flex, which Carbon says is ideal for comfort padding in helmet liners and safety gloves. EPU 45 has even higher damping and printability, which makes it suitable for sports upholstery and seats. EPU 43 has already been used in products from Hard Head Veterans and CCM, while products containing EPU 45 will soon be on the market.

The company also announced the expansion of its work with German chemical company Henkel, which resulted in the release of Henkel Loctite IND147, a rigid black resin with high stiffness, temperature resistance, dimensional stability and quality of elevated surfaces. Henkel suggests it’s ideal for trim, fixtures, and small rooms exposed to high heat. Because it is a single component resin, it does not require heat treatment and therefore is less expensive and less labor intensive than other resins for 3D printers from Carbon.

Climate-neutral PA 1101 and low-carbon PA 2200 from EOS

FORMIGA P 110 FDR polymer system

EOS has announced the release of two new nylon powders that are said to be less harmful to the environment. While the climate-neutral PA 1101 is a bio-based Selective Laser Sintering (SLS) polymer developed with Arkema, the PA 2200 CarbonReduced is said to have a 45% lower CO2e footprint than its traditional PA 2200 counterpart, as it is made from renewable energy. . Along with the new materials, EOS showcased its Fine Detail Resolution (FDR) 3D printer, capable of 40µm layer thicknesses and a minimum wall thickness of just 0.22mm. FDR technology is available with the new FORMIGA P 110 FDR polymer system.

Trumpf Large Format Copper 3D Printing

Trumpf has shown its ability to 3D print copper parts with its LPBF machines, including its largest system, the Tru-Print 5000. Using a green laser, the company says the traditionally difficult material is now as easy to print with as stainless steel. This resulted in the release of the Tru-Print 5000 Green Edition 3D printer. Additionally, Trumpf says it’s possible to do hybrid production with the technology, which means users can 3D print features like cooling channels onto milled or cast parts. It is also possible to repair turbine blades. Typically, such hybrid fabrication was more or less limited to directed energy deposition machines.

Roboze bio-based PA

Roboze, an Italian manufacturer of high-temperature extrusion 3D printers, has announced the release of a bio-based nylon material, reinforced with natural fibers. It has 60% less CO2 emissions than a carbon fiber reinforced petroleum-based PA. It has the added benefit of absorbing less water from the air, thus ensuring a stable Young’s modulus even in humid conditions. It is ideal for applications requiring a tensile strength of less than 60 MPa.

Arkema Photopolymers and Thermoplastics

French chemical company Arkema unveiled new photopolymers at Formnext. These included N3D-HITEMP062, which is described as a “high temperature hybrid material with excellent toughness and high HDT properties”. N3D-CAST063 is considered a high resolution material with a matte finish making it ideal for casting applications. Another unnamed elastomer material was also on display. It has an elongation at break of 170% and a tear strength of 33 kN/m.

In addition to the aforementioned PA1101, Arkema and EOS have launched a new Kepstan PEKK powder for EOS P 810 for electrical insulation and other high temperature applications. Together with Stratasys and Kimya, Arkema has also developed Kimya Kepstan PEKK-SC 3D for use on Stratasys extrusion machines.

With Continuous Composites, in which Arkema has previously invested, the French company has introduced PolyMat High Tg for printing continuous carbon and glass fibers and CeraMat ™ Carbon/Carbon resin is intended for the creation of precursor parts Carbon Bonded Carbon for ultra-high temperature applications.

Equispheres Inexplosive Aluminum

Equispheres Inc. of Ottawa, Ontario introduced a non-explosive LPBF aluminum alloy raw material. Called NExP-1, the material is not only ideal for 3D printing aluminum parts at high speed, due to the quality of Equispheres powder, but also for doing so without fear of explosion.
