Evonik, a number one specialty chemical compounds firm, and LEHVOSS Group, a chemical and mineral specialties group, are coming into right into a strategic partnership within the area of commercial 3D printing. The core content material of the collaboration consists of two key initiatives. Firstly, based mostly on Evonik’s PA613 polymer chemistry, LEHVOSS will develop its personal 3D printing formulations beneath its personal LUVOSINT product branding. Secondly, LEHVOSS will embody Evonik’s polymer powder INFINAM PA 6005 P (PA613) in its personal product portfolio from September 1, 2023. By means of this partnership, each business companions purpose to open up the way in which to new purposes within the automotive sector.

Materials consultants

“The collaboration with LEHVOSS could be very particular for us, as a result of that is the primary time in our three-decade historical past that we’re coming into right into a partnership with one other materials producer. The skilled crew at LEHVOSS is effectively positioned to provide specialty formulations that allow new 3D purposes,” stated Sylvia Monsheimer, head of commercial 3D printing at Evonik.

INFINAM PA 6005 P is a polymer powder from Evonik based mostly on polyamide 613 and is designed for 3D printing applied sciences similar to selective laser sintering (SLS). The polymer is produced utilizing Evonik’s particular precipitation course of on the Marl Chemical Park, in Germany, and is appropriate for 3D purposes within the increased temperature vary. In comparison with different difficult-to-process supplies of the polyamide 6 household, INFINAM PA 6005 P has an impressively low water absorption fee – lower than 3% – which has optimistic results on each the processability within the 3D printing course of, and the dimensional stability of the printed part.

New PA613-based formulations

LEHVOSS has developed a carbon fiber-reinforced powder variant for laser sintering created from Evonik’s PA613 base polymer. Marketed beneath the model identify LUVOSINT PA613 9711 CF, the product options particular carbon fibers compounded into the person polymer particles. Carbon fibers bonded on this manner are compliant with relevant occupational security laws. Moreover, by together with Evonik’s unreinforced INFINAM PA 6005 P into its personal product distribution portfolio, LEHVOSS now provides clients each of those formulations – all from one provider.

“Partnering with Evonik and utilizing their glorious base polymer made it simpler to develop a personalized product for our clients’ technical purposes,” stated Dr. Stefan Schulze, 3D printing crew chief at LEHVOSS.

With the LUVOSINT and LUVOCOM 3F product traces, the LEHVOSS Group provides modern and customised plastics for 3D printing. These merchandise are tailored to the most typical manufacturing processes, similar to Powder Mattress Fusion (PBF), Fused Filament Fabrication (FFF), and Fused Granulate Fabrication (FGF). These merchandise are characterised by good processability and glorious materials properties.
