AIM3D总部位于德国的多物质3D打印技术的开发人员已宣布推出其最新的3D打印机Formnext 2021。
Operating on the firm’s proprietary composite extrusion modeling (CEM) process, the new ExAM 510 can print with up to three different materials at the same time, including polymers, ceramics, fiber-filled composites, and even metals. The technology is known for its compatibility with readily-available injection molding pellets, which makes it significantly faster than conventional FFF processes.
打算作为先前启动的继任者考试255，AIM3D的新考试510打印机具有更大的形式的构建量，改进的打印精度和更快的打印速度。打印机的应用范围很广，涵盖了航空航天，汽车和医疗保健中的用例。
CEM 3D打印与AIM3D
AIM3D成立于2017年的Rostock市，其目标是开发一种结合性能和负担能力的多物质3D打印技术。CEM 3D打印的骨干是该公司申请专利的AIM3D CEM E-1挤出机，该设备能够处理直径3mm的几种颗粒材料。就目前而言，AIM3D当前提供一台市售的3D打印机 -考试255。
该技术的新颖性是它旨在与注射成型的颗粒一起使用，包括不锈钢等金属和诸如PEEK等高性能聚合物。
在金属构建的情况下，仅熔化了颗粒的聚合物成分。最初，这留下了由周围聚合物结合的金属粉末制成的脆弱的绿色部分。工作流程的下一步涉及删除塑料，最后烧结印刷零件以增加其密度并形成稳定的金属组件。
The ExAM 510 3D printer
AIM3D最新的3 d打印机功能的构建volume measuring 510 x 510 x 400mm, and can process up to two build materials and a support material simultaneously. One of the major advantages of pellet-based 3D printing is also the excellent print speed potential. The CEM E-1 extruder, specifically, delivers material flow rates up to ten times faster than run-of-the-mill filament extruders, enabling the ExAM 510 to achieve build rates of up to 250 cm³/h.
考试510的一个值得注意的功能是其广泛的材料功能。为了使用高温材料进行打印，可以将系统的构建室加热到200ºC，从而可以处理工程级聚合物，例如PEEK，PEI，PSU和PPS。就金属和陶瓷而言，用户将能够使用316升不锈钢，钛，铜，氧化铝，氧化铝，碳化硅等。
According to AIM3D, a material can be tested in around two working days and validated for production in 5 – 10 working days on the ExAM 510. Injection molding pellets are also significantly cheaper than equivalent 3D printing filaments. For example, PEEK filament is priced at around €700/kg, whereas PEEK pellets can be purchased for €50/kg, leading to significant material cost savings on the ExAM 510.
Clemens Lieberwirth, CTO of AIM3D, said, “The further development of our patented ExAM 255 machine into the ExAM 510 is a technological leap for us. So you could say we are now offering a faster, bigger, hotter and more precise CEM process technology for Additive Manufacturing.”
