Carbon 3D Spotlight Material of the Week
Carbon 3D EPU ElastomericÂ Polyurethane
Highly elastic, resilient
EPU is a high performance polyurethane elastomer from the Carbon 3D Family. It exhibits excellent elastic behavior under cyclic tensile and compressive loads. EPU is useful for demanding applications where high elasticity, impact and tear resistance are needed such as cushioning, gaskets and seals.
1.Â Problem Solver
3D Printing Elastomeric parts has long been a pain point of many engineers. Very limited options exist. Polyjet can create a look and feel model but does not have the properties to withhold actual testing. The next option would be to create a RTV Mold and inject a low durometer urethane. This adds time and cost. Carbon 3D solves one of the biggest engineering pain points by being able to print high performing elastomeric materials. Gaskets, O Rings and Seals everywhere rejoice!
The EPU is a high performance polyurethane elastomer from the Carbon 3D Family. The material behavesÂ similarly to injection-molded elastomers, exhibiting elastic behavior over a wide temperature range. It has excellent tear strength, compressive strength and elasticity. The material can fit into any production application where a molded elastomer would have been used.
This video demonstrates the tear strength, compressive strength, and elasticity of EPU. A mesh structure is twisted, pulled, and repeatedly crushed by a push roller. This showcases EPU’s spring-like properties as it compresses under load and recovers quickly without deformation or abrasion.
