Selective Laser Sintering of Zirconium Silicate
Abstract
The Fraunhofer Institute of Production Technology (IPT) and the Fraunhofer Institute of
Laser Technology (ILT) have joined forces in a project dedicated to Selective Laser Sintering
(SLS) ofmetals and ceramics, funded by the German Government and 6 industrial partners.
Selective Laser Sintering of zirconium silicate as a ceramic material used for investment
casting shells and cores is an attractive alternative to the conventional, time-consuming way of
producing these shells from a wax master. This paper will present current process results
concerning laser sintering of shells made from zirconium silicate and explain the related
potentials and benefits.
