Laser Micro Sintering – a Versatile Instrument for the Generation of Microparts

Abstract

Miniaturization is one of the main imperatives in high‐tech development and therefore a persistent challenge for mechanical engineering. Recently a freeform technique – Laser Micro Sintering – has been developed by which micro parts with an overall resolution of 30 μm can be produced from powder materials. The technique is a generative freeform fabrication method based on selective laser sintering; it can produce hollows and undercuts and does not afford shape‐specific tools. Functional micro bodies can be generated from metals and ceramics.
