Polyurethane Elastomer for 3D Printing - Carbon DLS
EPU 45 (DLS) – High-Performance Polyurethane Elastomer for 3D Printing
EPU 45 is a next-generation polyurethane elastomer developed by Carbon to deliver superior performance in 3D printing applications. Leveraging the Digital Light Synthesis™ (DLS) technology, this elastomer enables the production of complex components with precise geometries and exceptional detail.
Impact-Responsive Polyurethane Elastomer
One of the key advantages of EPU 45 Carbon DLS is its strain rate sensitivity, meaning its mechanical properties adjust based on the speed of deformation. In practical terms, the material becomes stiffer under high-speed impacts, effectively absorbing energy and protecting both components and users. This unique characteristic allows engineers to design lattice structures, interconnected mesh or cellular geometries, that remain soft and breathable at low speeds while providing high energy absorption under fast impacts.
Result: a versatile material that dynamically adapts to different conditions, offering both comfort and protection in industrial and technical applications.
Il risultato è un materiale versatile, capace di adattarsi dinamicamente alle diverse condizioni di utilizzo, garantendo sia comfort sia protezione.
Grazie a queste caratteristiche, l’EPU 45 consente la realizzazione di una vasta gamma di forme e geometrie reticolari con un alto rendimento e prestazioni affidabili nel tempo.
