Xerion德国工业炉和3 d打印机manufacturer, has introduced the Fusion Factory, a three-part FDM/FFF system capable of printing metal and ceramics.
该公司从多模块化系统中汲取了灵感，以制造一台可以与金属注塑成型（MIM）技术。
FDM/FFF金属印刷
Dr. Uwe Lohse founded Xerion Advanced Heating in 1997. In 2016, a subsidiary called Xerion Berlin Laboratories was founded for the development of 3D printing technology. Both companies now form the Xerion Group.
Xerion的最新成就是基于FDM的金属3D打印机。如前所述，etal FDM/FFF printing is possible using metal composite filaments, such as虚拟铸造厂的丝。Industrial companies are also experimenting with metal filaments. For example,三角形is testing metal filaments由德国化学生产商制造巴斯夫。
但是，金属丝与聚合物混合，因此不具备纯属的特性。
Xerion’s Fusion Factory overcomes this limitation by将打印，脱夹和烧结结合到一个系统中。融合工厂生产的零件纯粹是由金属或陶瓷制成的，密度在98-99％之间。
The Fusion Factory
融合工厂分为三个部分，一个3D打印机，一个拆卸站和电气炉。
The 3D printer is like any FDM/FFF printer except with a modified nozzle and feed mechanism made of hundred-percent stainless steel. The printer can print metal or ceramic composite filament on a build volume of 24.5 cm x 23 cm x 20 cm.
印刷零件后，将其移至删除站，并将其浸入化学溶液中。这个过程在很大程度上是自动化的，机器的操作员不会以任何方式与化学溶液接触。
After a few hours in the debinding solution, the part is removed. At this stage, the 3D printed part is free of non-metal particles and contains only metal (or ceramic, depending on the filament used). Therefore the part is fragile. To make into a fully finished metal (or ceramic) part, the component is运输到专门设计的电炉。在这里，它在1000以上的温度下烧结°C持续十多个小时。在炉子中，金属融化并融合以制成完整的金属部分。
Some part shrinkage does occur during sintering but this can be countered during the modeling stage.
融合工厂的未来
当前可用的技术，尤其是金属粉融合，因为粉末可发炎，可能会不便且有害。Lohse博士使用金属细丝解释说：“您没有粉末处理的问题。当然，灯丝很容易且方便地处理。您的丝线线轴可以很快交换。”
此外，FDM金属印刷提供了将填充物添加到一部分的选择，从而可以提高其强度。
Dr Lohse further said, “The printer also features a dual extruder, which means that it can print with two different filaments at the same time, which opens up the possibility of mixing the filaments to produce parts made up of metal and ceramic compounds.”
在未来,debind Xerion想让ing module without a solvent, and integrate a 3D scanner into the system that could compare the printed model with the CAD file to find inconsistencies.
The Fusion Factory system is priced at $283,000.
