INFLUENCE OF SCANNING SPEED ON THE MECHANICAL AND STRUCTURAL PROPERTIES OF LASER SINTERED PROTOTYPES

This paper presents the elaboration of the method, the laboratory equipment and the technology (developed in the department) of Selective Laser Sintering for preparation specimens from a Fe-Ni-Cu (-P) powder mixture. During the investigation we focused on the influence of the scanning speed upon the mechanical and structural properties of specimens. The laser-sintered probes were investigated by light microscopy, compression test and laser topography. The optimum scanning speed was established for 150 W laser power, 0.1 mm scanning distance and 0.1 mm layer thickness
