Laser sintering is described as an efficient and successful technique for the fast and direct production of complex-shaped prototypes of technical ceramics. After presentation of the state of the art of laser sintered silicon infiltered silicon carbide (SiSiC) the paper describes new aspects of material development. Finer raw SiC powders are used and an additional carbon dotation process is established. The significantly higher SiC/Si phase ratio in the ceramic material results in increasing the 4-point flexural strength from 196 to 267 MPa.
