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 cm$+3$/ 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$DOT@cm$+$MIN@3$/. Schemes of the laser stereolithography plants based
upon the excimer laser and the cw UV lasers are considered, and their
productivity evaluations are presented.
