INFLUENCING SPECIFIC MECHANICAL PROPERTIES OF THREE-DIMENSIONAL OBJECTS MANUFACTURED BY A SELECTIVE SINTERING BY MEANS OF ELECTROMAGNETIC RADIATION FROM A POWDER COMPRISING AT LEAST ONE POLYMER OR COPOLYMER

摘要

A three-dimensional object is manufactured from a powder of polymer material by selective sintering process by means of electromagnetic radiation of the powder, wherein the powder comprises a preselected polymer or copolymer and is subjected to selective sintering such that the manufactured three-dimensional object has a final crystallinity which is in such a range that the balance of properties, in particular mechanical properties including Young's modulus, tensile strength and elongation at break, is improved.
