Abstract | The invention relates to a method for treating surfaces of plastic objects, wherein in a dying step - a mixture of dyes is produced, wherein a dye (e.g. a metal complex dye) is dissolved in a solvent, wherein between 0.05 g and 50 g of the dye is added to each liter of solvent - the dye mixture is heated to a dying temperature of between 60 °C and 180 °C and - the plastic objects are placed in the heated dye mixture for a period of between 5 minutes and 6 hours for dying. The invention further relates to a plastic object, in particular a polyamide-molded part, wherein the surface of the plastic object is treated with the method according to the invention. The plastic objects are preferably manufactured by a 3D-printing method. |
