Additive Manufacturing: Production-Ready Materials For 3D Printing
One is an elastomeric PUR.
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.
Plenty of companies are taking advantage 3D printing’s disruptive nature in the manufacturing space, but I came across an Amsterdam-based startup that is taking the disruptive concept even further.
Many plastics processors are just starting to become familiar with the terms “additive manufacturing” or “additive fabrication,” which refer to a group of processes that build up parts by successively adding material, often in layers.
Perhaps you have heard that additive manufacturing—a.k.a. 3D printing—can be used to make injection tooling inserts out of plastics—relatively quickly, at relatively low cost, and with little human labor involved.
