Use of polyester powder in a laser sintering layer-by-layer process for producing a three dimensional article

摘要

Disclosed is a layer-by-layer process for production of a three-dimensional component using powder, in which regions of the respective powder layer are selectively melted via input of electromagnetic energy, wherein the powder comprises at least one polyester prepared via polycondensation of a di- or polyhydric aliphatic alcohol and of an aliphatic diacid.
