  • Patent number: 11732133
    Abstract: A process for producing a three-dimensional object by selectively layer-by-layer solidification of a powdery material layer at the locations corresponding to the cross-section of the object in a respective layer by exposure to electromagnetic radiation. The powdery material comprises at least one polymer which is obtainable from its melt only in substantially amorphous or completely amorphous form, or a polyblend which is obtainable from its melt only in substantially amorphous or completely amorphous form. The powdery material has a specific melting enthalpy of at least 1 J/g.
