Method of additive manufacture of components, comprising the steps of: a) laying at least two different pulverulent components having a difference in melting point of ≥ 50°C once or more than once on a substrate or on an already laid layer, where the pulverulent component having the lowest melting point is laid in the form of the component and the pulverulent component having the highest melting point as the negative thereof in a layer; b) subjecting the powder layer to heat treatment at a temperature above the melting point of the component having the lowest melting point and below the melting point of the component having the highest melting point, wherein the powder constituents of the component having the lower melting point are melted and at least partially fused; c) cooling the heat-treated powder layer from step b) down to a temperature below the melting point of the lowest-melting component and d) removing the unfused pulverulent components to obtain the component, characterized in that either: the pulverulent component having the lowest melting point is selected from the group consisting of polyetheretherketone (PEEK), polyaryletherketone (PAEK), polyetherketoneketone (PEKK), polyethersulfones, polyimide, polyetherimide, polyester, polyamides, polycarbonates, polyurethanes, polyvinylchloride, polyoxymethylene, polyvinylacetate, polyacrylates, polymethacrylates, polyethylene, polypropylene, polylactide, ABS (acrylonitrile-butadiene-styrene copolymers), PETG (glycol-modified polyethylene terephthalate), polystyrene or mixtures of at least two of the aforementioned polymers, and in that the pulverulent component having the highest melting point is an inorganic salt of the alkali metals, an inorganic salt of the alkaline earth metals or a mixture of at least two of the aforementioned salts, or: the pulverulent component having the lowest melting point is polychloroprene, polybutadiene, polybutadienenitrile, hydrogenated polybutadienenitrile (HNBR), ethylene-vinyl acetate, fluoro rubber, styrenebutadiene block copolymers, polyvinylchloride, polyvinylacetate, polyfluoroethylene (PTFE) or polyarylsulfone, and in that the pulverulent component having the highest melting point is NaCl, MgSO 4, MgCl 2 or CaSO 4, except that CaSO 4 is not intended for polyfluoroethylene (PTFE). a) laying at least two different pulverulent components having a difference in melting point of ≥ 50°C once or more than once on a substrate or on an already laid layer, where the pulverulent component having the lowest melting point is laid in the form of the component and the pulverulent component having the highest melting point as the negative thereof in a layer; b) subjecting the powder layer to heat treatment at a temperature above the melting point of the component having the lowest melting point and below the melting point of the component having the highest melting point, wherein the powder constituents of the component having the lower melting point are melted and at least partially fused; c) cooling the heat-treated powder layer from step b) down to a temperature below the melting point of the lowest-melting component and d) removing the unfused pulverulent components to obtain the component, characterized in that either: the pulverulent component having the lowest melting point is selected from the group consisting of polyetheretherketone (PEEK), polyaryletherketone (PAEK), polyetherketoneketone (PEKK), polyethersulfones, polyimide, polyetherimide, polyester, polyamides, polycarbonates, polyurethanes, polyvinylchloride, polyoxymethylene, polyvinylacetate, polyacrylates, polymethacrylates, polyethylene, polypropylene, polylactide, ABS (acrylonitrile-butadiene-styrene copolymers), PETG (glycol-modified polyethylene terephthalate), polystyrene or mixtures of at least two of the aforementioned polymers, and in that the pulverulent component having the highest melting point is an inorganic salt of the alkali metals, an inorganic salt of the alkaline earth metals or a mixture of at least two of the aforementioned salts, or: the pulverulent component having the lowest melting point is polychloroprene, polybutadiene, polybutadienenitrile, hydrogenated polybutadienenitrile (HNBR), ethylene-vinyl acetate, fluoro rubber, styrenebutadiene block copolymers, polyvinylchloride, polyvinylacetate, polyfluoroethylene (PTFE) or polyarylsulfone, and in that the pulverulent component having the highest melting point is NaCl, MgSO 4, MgCl 2 or CaSO 4, except that CaSO 4 is not intended for polyfluoroethylene (PTFE).
