Colouring of polymer products manufacturing by selective laser sintering

With additive manufacturing it is possible to create products with complicated geometry from 3D data in very short time, which is very difficult or even impossible to do with other manufacturing technologies. However, there are many limitations, primarily in the selection of plastic materials and available colours. Also the problem occurs for different additive processes in the appearance of the final surface.Thus, the process selective laser sintering – SLS uses plastic powder that gives a high surface roughness and products can be made only in one colour – white. The paper will provide a brief overview of SLS, processes of colouring and different surface treatment of polyamide products made by SLS after surface treatment and without it.
