Exactly a year after restructuring its additive manufacturing business, Dutch chemicals company Royal DSM has unveiled two “groundbreaking” materials for 3D printing, which it says set new industry standards.

The company launched Somos PerFORM Reflect during the Formnext 3D printing trade show, held 13-16 Nov in Frankfurt, Germany, new stereolithography material for wind tunnel testing with PIV (particle imaging velocimetry). 

The new material eliminates the need to apply PIV coatings to the printed parts, thus reducing the amount of post-processing by 30%.

Applications include in F1 prototyping, where typically a car body is printed at 60% of its normal size for simulation purposes and checked with PIV.

“Eliminating the need to apply PIV coatings is a major breakthrough for customers who are using PIV wind tunnel testing. It allows them to speed up their aerodynamic design optimisations," said Hugo da Silva, vice president of additive manufacturing at DSM. 

The new material, said DSM, is developed through a technology that allows for “reducing and even eliminating” much of the finishing work required with traditional materials.

Based on DSM’s industry standard Somos PerFORM, the new resin has performance attributes such as low viscosity, low settling, fast processing and high stiffness and heat resistance, according to the company.

DSM also launched its new thermoplastic copolyester (TPC) Arnitel ID2060 HT for Fused Filament Fabrication (FFF) at the show.

The TPC material, said DSM, is an industry “first”, combining flexibility with chemical resistance against EGR (exhaust gas recirculation) and prolonged high temperature resistance in a single material. 

Parts printed can resist sustained high temperatures of 175° C (1000 hours) or 190°C (500 hours) and chemicals such as EGR condensate. Such features make the new material ideal for under-the-hood applications in the automotive industry.

The development of the new products, according to Da Silva, have been a result of DSM’s focus on applications.

“It is through a thorough understanding of the challenges and processes of our customers that we can continue to deliver valuable innovations,” he added.

DSM restructured its additive manufacturing activities last November, clustering all the activities within a newly-formed DSM Additive Manufacturing business.

The new unit, headed by Da Silva, explores new and emerging technologies through an “ecosystem” approach, which involves forming partnerships with players across the value chain.
