Abstract (en)
[origin: DE19820725A1] Three-dimensional polymeric patterns are prepared by laser sintering of homopolymer or copolymer beads (2-200 microns) of monoethylenically unsaturated compounds. Three-dimensional polymeric patterns are produced by data-controlled laser radiation (wavelength of 200-20,000 nm). One or more laser beams are guided through specific spatial zones of a bed of fine particulate polymer powder according to the geometric data and the material melted and/or sintered. The polymer powder comprises polymer beads of a homopolymer or copolymer of monoethylenically unsaturated compounds having a particle diameter of 2-200 microns. An Independent claim is included for the resulting three-dimensional pattern.
