Carbon, a Silicon Valley-based digital 3D Manufacturing company, announced two new additive manufacturing materials: Epoxy (EPX) 82 and Elastomeric Polyurethane (EPU) 41.
EPX 82 is an accurate and high-strength engineering material with long-term durability, while EPU 41 is a production-scale elastomeric material with high resilience for making elastomeric products.
EPX 82
EPX 82 has a heat-deflection temperature of 125°C and good impact strength, making it suitaable for applications requiring a balance of strength, toughness, and thermalcycling durability such as connectors, brackets, and housings in the automotive and industrial sectors. Its mechanical properties are comparable to lightly glass-filled thermoplastics (e.g. 20% GF-PBT, 15% GFNylon) and meet the USCAR-2 fluid compatibility standards.
EPU 41
The launch of EPU 41 adds to Carbon’s elastomeric material family (EPU 40, SIL 30, and EPU 41), and is suited for producing elastomeric lattice geometries that can outperform traditional foams. It has higher resilience and better low-temperature performance compared to EPU 40, and its combination of tear strength, energy return, and elongation make it suitable for cushioning, impact absorption, and comfort. EPU 41 also performs well in functional testing, including fatigue, hydrolysis, UV-stability, and plastic deformation tests.
Customers can combine the performance of EPU 41 with Carbon’s library of tunable elastomer lattices and software tools to rethink comfort, safety and performance benchmarks once set by foam products. Carbon’s software tools eliminate many trial-and-error processes when creating lattices, enabling designers and engineers to test load requirements of their part, confirm it can be manufactured using Digital Light Synthesis technology, and create multiple functional zones that distribute different mechanical properties within the same part.
EPU 41 is offered only in five-liter bulk packaging, and is the second material (after Rigid Polyurethane 70) to be offered under the Carbon production-scale materials pricing of $150 per liter. It requires an MMD (meter, mix, and dispense) for proper dispensing of the material in bulk quantities.
EPX 82 and EPU 41 are currently available to Carbon customers in North America. Information about global availability will be shared at a later date.
