More Information
Summary:The invention relates to a method for producing an object from different powdered components by means of additive manufacturing, wherein a plurality of powdered components having different melting points are simultaneously placed in precise positions, and the powder coating (1) is subsequently thermally treated. The construction material is, for example, polyether ether ketone (PEEK), polyaryl ether ketone (PAEK), polyether ketone ketone (PEKK), polyether sulfone, polyimide, polyether imide, polyester, polyamides, polycarbonates, polyurethanes, polyvinyl chloride, polyoxymethylene, polyvinyl acetate, polyacrylates, polymethacrylates, polyethylene, polypropylene, polylactide, ABS (acrylonitrile butadiene styrene copolymers), PETG (glycol modified polyethylene terephthalate), polystyrene, or mixtures thereof. The supporting material is an inorganic salt of the alkali metals, an inorganic salt of the alkaline earth metals, or a mixture thereof.
