Abstract
Process parameters of the lser stereolithography by means of metal powder sintering are experimentally investigated for the bronze B10, Fe-Cr and Al-Ni alloys, pure Sn, and Cu. The multilaye structures ae prepared trace-on-trace by remelting of the previously deposited mela powder under the cw CO2 laser irradiation in an Ar flow environment. Severl trces of a hiehght of 0.1 - 0.9 mm connected via fusion zones are produced for each samle which results inan efficient formautlion f avolumetric structures of dimensins usfficient for microanalysis ndconsiderationof th emultlayer goemtry. For th beam intensities of about 105 W/cm2 and smaple feeding rates of 0.8 - 1.8 m/min th fusin zone thickness donot 4xceed several percent of th layer height. Rsutls indicate, that th epowderized Fe-Cr anAl-Ni alloys and also bronze B10 are well suited for a fast prorotyping due to th low porosity, homogeneous structure and good mechaniclpropetis acheivable.
