Enabling the ARBURG Freeforming process for industrial production of metallic components

其主要目标是使ARBURG（阿博格）金属自由成形工艺能够经济、可持续地生产金属部件。特别是，这涉及增加排放系统的耐用性，提高输出的再现性，提高构建速率，并使该过程能够使用具有更大粉末颗粒直径的悬浮液。增加排放系统的耐用性需要修改机械设计并选择适当的材料以增加耐磨性。通过开发新的控制策略可以实现更高的再现性。建造率的增加需要排放系统的关闭机构的几何形状修改以及体积排放控制的修改。在修正封闭机构的力学时，必须考虑较大粉末粒径的悬浮加工。海德堡印刷机械公司的一个结构组件，以验证修改后的机器和控制策略。部件采用316 L不锈钢，满足真实的生产要求。

The primary objective is to enable the already researched ARBURG metallic freeforming process for the economical and sustainable production of metal components. In particular, this involves increasing the durability of the discharge system, improving the reproducibility of the output, increasing the build rate and enabling the process to use suspensions with larger powder particle diameters. Increasing the durability of the discharge system requires a revision of the mechanical design and the selection of appropriate materials to increase wear resistance. Higher reproducibility can be achieved by developing a new control strategy. The increase of the build rate requires a geometry revision of the closing mechanism of the discharge system as well as the revision of the volume discharge control. When revising the mechanics of the closure mechanism, the suspension processing with larger powder particle diameters must be considered. A structure component of the company Heidelberger Druckmaschinen is provided to validate the revised machine and control strategy. The component shall be made of 316L stainless steel and shall meet the requirements of real production.
