EOS, the German based manufacturer and supplier of industrial 3D printers that utilize its proprietary laser sintering process, has announced new materials for both the plastic and the metal platforms. On the plastics front, EOS has introduced two new materials — PrimePart ST (PEBA 2301) and PrimePart FR (PA 2241 FR). For the Direct Metal Laser Sintering (DMLS) platform, EOS has announced the immediate commercial introduction of EOS NickelAlloy HX.
PrimePart ST是一种柔软，柔性和弹性材料，被归类为热塑性弹性体，可立即用于eosint P 395系统。在接下来的几个月中，它也将用于EOS Formiga P 110和Eosint P 760系统。PrimePart®ST的开发是为了支持柔性，类似橡胶的零件的生产 - 进行了优化，以确保即使在显着变形后，零件也将恢复其原始形状。此外，后期制作浸润对于达到出色的机械性能和表面质量并不是必需的。EOS称，在-40至90°C的温度范围内，PrimePart ST材料表现出非常好的疲劳性能。PrimePart FR是一种耐火聚酰胺12材料，现在可用于当前的osint P 395和P 760系统，以及eosint P 390和P 730。拉伸强度为49 MPa，伸长率为15％。这意味着PrimePart®FR超过了极为成功的PA 2210 FR，直到现在，这是EOS投资组合中唯一的震动PA 12材料。飞机内部领域的典型应用将包括通风管和出口通风口。
In a further development in line with client feedback, the EOS NickelAlloy HX material is a heat and corrosion resistant nickel-chrome-iron-molybdenum alloy, which distinguishes itself through a high degree of strength and its resistance to oxidization, even at high temperatures. For this reason it will see frequent application in temperatures up to 1200ºC. The material is optimized for processing in the EOSINT M 280 metal system, and is typically processed with a layer-thickness of 20 µm.
