Carbon, Silicon Valley, announced two new materials offerings for 3D printing at NPE2018: Epoxy (EPX) 82 and Elastomeric Polyurethane (EPU) 41. EPX 82 is a high-resolution and high-strength engineering material with excellent long-term durability, while EPU 41 is the company’s production-scale elastomeric material offering higher resilience for making durable, elastic lattices.

EPX 82 is a high-strength engineering material with a heat-deflection temperature of 239 F (115 C) and good impact strength, making it ideal for applications requiring a balance of strength, toughness, and thermal-cycling durability such as connectors, brackets, and housings in the automotive and industrial indutries. Its mechanical properties are reportedly comparable to lightly glass-filled thermoplastics (e.g., 20% GF-PBT, 15% GF-Nylon) and meet the USCAR-2 fluid compatibility standards. The launch of EPU 41 adds to Carbon’s elastomeric materials families (SIL 30, EPU 40, and EPU 41), and is especially well-suited for producing elastomeric lattice geometries that can outperform traditional foams. It has higher resilience at room and low temperatures compared to EPU 40, and its tear strength, energy return, and elongation make it ideal for cushioning, impact absorption and comfort.
