增材制造工艺在过去几年中获得了巨大的意义。金属部件最常用的增材制造技术是用于生产新部件的选择性激光熔化（SLM）和用于修复和修改现有部件的激光金属沉积（LMD）。由于它们无需工具制造，并且提供了很大的几何自由度，因此这些增材制造工艺可以生产功能优化的部件，例如在汽车，工具以及航空和涡轮结构中。由于这个原因，这些流程越来越多地进入工业制造链。迄今为止，SLM和LMD工艺，机器和应用都集中在制造最小结构尺寸在bb0 - 200微米范围内的宏观零件。为了扩大结构尺寸为200µm的微型零件的应用范围。为了扩大结构尺寸<100µm的微型零件的应用范围，必须相应地发展工艺和设备。本文介绍了该技术的基本原理。
Additive manufacturing processes have gained great significance in the last several years. The additive manufacturing techniques most commonly used for metallic components are the laser based processes Selective Laser Melting (SLM) for producing new parts and Laser Metal Deposition (LMD) for repairing and modifying existing components. Since they manufacture without tools and offer a great freedom of geometry, these additive processes enable functionally optimized components to be produced, e.g. in automobile, tools as well in aviation and turbine construction. For this reason, these processes are increasingly making their way into industrial manufacturing chains. To date SLM and LMD process, machines and applications are focused on manufacturing of macro parts with minimum structure sizes in the range >200µm. In order to enlarge the range of application towards micro scale parts with structure sizes 200µm. In order to enlarge the range of application towards micro scale parts with structure sizes <100µm, process and equipment has to be developed accordingly. In this paper the basic principle of the pr...
