Abstract
The present invention relates to the use of a thermosetting polymeric powder composition in a Selective Laser Sintering process to produce a 3D duroplast, wherein the composition comprises at least one curable polymeric binder material and wherein during each pass of the SLS process said polymeric binder material is at least partially cured within the layer thus formed and also at least partially crosslinked with the previous layer. The invention furthermore relates to a SLS process using such a thermosetting polymeric powder composition and a 3D-printing product obtained when using such a thermosetting polymeric powder composition.
Claims17
A method of producing a 3D duroplast, the method comprising using a thermosetting polymeric powder composition in a Selective Laser Sintering (SLS) process, wherein the composition comprises at least one curable polymeric binder material and wherein during each pass of the SLS process said polymeric binder material is at least partially cured within the layer thus formed and also at least partially crosslinked with the previous layer.
A 3D duroplast produced by a Selective Laser Sintering (SLS) process comprising the steps of:
- providing a thermosetting polymeric powder composition comprising at least one curable polymeric binder material;
- sintering the composition such that the polymeric binder material is at least partially cured within a layer thus formed and at least partially crosslinked with a previously printed layer;
- wherein the at least partial curing of the polymeric binder material leaves free functionalities for curing and/or crosslinking with a subsequent printed layer.
