Abstract The liquid silicon infiltration of laser sintered C-SiC parts (LS2I) is a solid freeform fabrication technique which allows the production of complex shaped Si/SiC prototypes. A mixture of SiC powder and reactive polymer binder is used in the laser sintering process to generate a porous green part. In the postprocessing, the porous green part structure has to be infiltrated with a precursor resin, carbonised and finally infiltrated with molten silicon. The infiltrated silicon reacts with the residual carbon to build beta-SiC. Results generated by the use of reduced primary particle sizes as well as alternative infiltration materials and the use of other RP- techniques for the green part fabrication will be discussed in this paper.
