Abstract
Three-dimensional shaped products are prepared by a layer-by-layer moldless production process in which at least one powder layer is provided, regions of the respective powder layer are selective melted via input of electromagnetic energy, wherein the powder of the powder layer contains at least one polymer powder or copolymer powder produced from a dispersion which contains at least one polymer or copolymer and which contains a water-soluble component, the water-soluble component containing at least one oligosaccharide.
Claims22
A process for the layer-by-layer moldless production of three-dimensional shaped products, comprising:
- providing at least one powder layer,
- selective melting of regions of the respective powder layer via input of electromagnetic energy,
- wherein said powder of said powder layer comprises at least one polymer powder or copolymer powder produced from a dispersion which comprises at least one polymer or copolymer and which comprises a water-soluble component,
- said water-soluble component comprising at least one oligosaccharide.
