Stereolithographic process for the fabrication of three-dimensional articles by using polyester powder and article obtained by said process

摘要

In a layer-based method for preparing three-dimensional components using powder, involving selectively fusing regions of each powder layer by input of electromagnetic energy, the powder contains at least one polyester (I), prepared by polycondensation of a di- or polyhydric alcohol (II) and an aliphatic diacid (III). An independent claim is included for shaped articles produced by the process.
