Abstract

The results of layer-by-layer objects manufacturing from liquid acrylic oligomers by pulsed- periodic excimer XeCl-laser beam (lambda equals 308 nm) and cw He-Cd laser beam are presented. Productivity and power consumption of the layer-by-layer manufacturing by laser beam photo-initiated oligomer polymerization were evaluated. Samples with an overall volume of 1000 cm³ were fabricated by projection printing method (XeCl-laser) and by direct laser drawing (He-Cd laser), and it was shown that the laser beam energy consumption during the objects manufacturing with layers thickness h of 0.1 - 0.2 mm had not exceeded 1 - 2 J(DOT)cm^-3. Schemes of the laser stereolithography plants based upon the excimer laser and the cw UV lasers are considered, and their productivity evaluations are presented.
