Title: METHOD FOR PRODUCING A THREE-DIMENSIONAL OBJECT
Abstract:
A method for producing a three-dimensional object by selective layered solidification of a powdered material at the points corresponding to the cross section of the object in each layer by means of the action of electromagnetic radiation. The powdered material comprises at least one polymer which can be provided from the melt merely in substantially or completely amorphous or completely amorphous form, or a polymer blend which can be provided from the melt merely in substantially or completely amorphous or completely amorphous form. The powdered material has a specific melt enthalpy of at least 1 J/g.
