Carbon Printers EPU 44 Biobased Elastomer for 3D Printing
Categories:	Polymer; 3D Printing/Additive Manufacturing Polymer; Thermoset; Epoxy
Material Notes:	2 part liquid. Available in gray or white. EPU 44 is production-scale, resilient elastomer that is highly resilient, tear resistant, and has a 40% bio-based formulation. EPU 44 enables lighter lattices than EPU 41 when designed with equivalent stiffness, requiring less material. EPU 44 has a higher green strength as well, allowing for more printable geometries. EPU 44 prints faster than EPU 41, and its higher green strength helps protect yield of delicate designs. Information provided by Carbon®
