AIM3D, a Germany-based developer of multi-material 3D printing technology, has announced the launch of its latest 3D printer atFormnext 2021.
在公司专有的复合挤出建模（CEM）过程中，新考试510可以同时使用多达三种不同的材料打印，包括聚合物，陶瓷，充满纤维的复合材料，甚至金属。该技术以与易于使用的注射成型颗粒的兼容性而闻名，这使其比常规FFF工艺要快得多。
Intended as a successor to the previously launchedExAM 255, AIM3D’s new ExAM 510 printer sports a larger-format build volume, improved print precision, and faster print speeds. The printer’s applications stretch far and wide, covering use cases in aerospace, automotive, and healthcare.
CEM 3D printing with AIM3D
Founded in 2017 in the city of Rostock, AIM3D set out with the goal of developing a multi-material 3D printing technology that combines performance and affordability. The backbone of CEM 3D printing is the company’s patent-pending AIM3D CEM E-1 extruder, a device capable of processing several types of granular materials up to 3mm in diameter. As it stands, AIM3D currently offers one commercially available 3D printer –考试255.
The novelty of the technology is that it’s designed to work with the pellets used in injection molding, including metals like stainless steel and high-performance polymers like PEEK.
In the case of metal builds, only the polymer component of the pellets is melted. This initially leaves a fragile green part made of metal powder bound by the surrounding polymer. The next step of the workflow involves debinding the plastic and, finally, sintering the printed part to increase its density and form a stable metal component.
考试510 3D打印机
AIM3D的最新3D打印机具有尺寸为510 x 510 x 400mm的丰盛构建量，并且最多可以同时处理两种建筑材料和支持材料。基于颗粒的3D打印的主要优点之一也是出色的打印速度潜力。CEM E-1挤出机，具体来说，材料流速的速度比矿体式挤出机的速度快10倍，从而使考试510达到高达250cm³/h的构建速率。
One noteworthy feature of the ExAM 510 is its extensive material capabilities. To enable printing with higher temperature materials, the system’s build chamber can be heated to 200ºC, allowing for the processing of engineering-grade polymers such as PEEK, PEI, PSU, and PPS. As far as metals and ceramics go, users will be able to work with 316L stainless steel, titanium, copper, aluminum oxide, zirconia, silicon carbide, and more.
根据AIM3D的说法，可以在大约两个工作日内测试一种材料，并在考试510的5 - 10个工作日内进行了验证。注射成型颗粒也比同等的3D打印细丝便宜得多。例如，PEEK丝的价格约为700欧元/公斤，而Peek颗粒的价格可以每公斤50欧元，从而在考试中节省了大量材料成本510。
克莱门斯·利伯特（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.”
