Abstract

PROCESS FOR PRODUCING THREE-DIMENSIONAL OBJECTS BY MEANS OF MICROWAVE RADIATION The present invention relates to a process for bonding material to produce three-dimensional objects (7) by means of selective heating via microwave radiation. Unlike selective laser sintering the present process for producing three-dimensional objects uses the type of simple microwave radiation available in any household. The selectivity of heating is achieved by applying a susceptor (4) to certain subregions of a layer composed of a pulverulent substrate (2), and then heating the susceptor (4) by means of microwave radiation. The heated susceptor (4) transfers the energy present therein to a pulverulent substrate (2) surrounding the susceptor (4), and the substrate (2) is thereby melted, giving firm bonding within the substrate (2) after cooling.
