Highly Resilient, Tear Resistant, 40% Bio-Based
EPU 44 is production-scale, resilient elastomer that is highly resilient, tear resistant, and more sustainable due its 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.
As a production scale offering, EPU 44 is only offered as a General Factory product, requiring industrial-class dispensing, cleaning, and baking equipment. It is comparable to commercial TPUs with a Shore A hardness of 70.

Example Applications
Cushioning with Elastomeric Polyurethane
Bouncy elastomeric lattices maximize comfort with precision tuning of energy return. EPU 44 offers new ways to optimize these parts. 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.
These applications combine a need for sustainability, high resilience, tear resistance, and energy return, in addition to isotropy, great surface finish, and accuracy.
