Abstract
In the field of layer manufacturing technologies the Fraunhofer Institute of Production Technology IPT is involved in the development of the direct laser sintering of ceramic powders.
Two different applications are investigated, currently: the laser sintering of ceramic master patterns for metal spraying of carbon steel moulds (Rapid Tooling) and the direct laser sintering of investment casting components (Rapid Prototyping & Rapid Manufacturing).
To realise these applications, special ceramic powders (Si02 and ZrSiO4) by means of grain size distribution, grain shapes and composition as well as new process parameter combinations have been examined.
