Advanced rapid prototyping technologies and nanofabrication

The selective laser micro sintering (SLS), which was developed by the Laserinstitut Mittelsachsen e.V. (Ebert 1999) is used for generation of micro parts. Tungsten and tungsten alloys (especially tungstenaluminium) were employed as the first usable metal powders for laser micro sintering (Regenfuss 2003), (Exner 2003). Meanwhile many new materials were investigated (Regenfuss 2005).
