Technology & Products
Key Products
LeanSint; Custom PC powder for PBF-LB/P; Recycled PA12 powder
Technological Advantage
CLAIMED: Extrusion-pulverized powders outperform ground powders on flowability and bulk density metrics critical for SLS/binder jetting consistency. VERIFIED: Fraunhofer IPA feasibility study on PC powder validates technical approach. Advantage appears replicable but differentiated by process know-how and customization capability.
Differentiation
Value Proposition
Enables AM users to source custom-formulated thermoplastic powders (including recycled PA12) with superior flowability and bulk density versus conventionally ground powders, reducing material bottlenecks for SLS and binder jetting production runs.
How They Differentiate
Extrusion-based pulverization produces powders with superior flowability and bulk density compared to traditionally ground polymer powders; offers custom formulations and recycled material (PA12) not widely available from incumbent material suppliers.
Market & Competition
Target Customers
Industrial AM users and OEMs requiring custom or recycled polymer powders for powder bed fusion processes
Industry Verticals
