Process for producing an article, comprising the step of producing the article by means of an additive manufacturing method from a construction material, wherein the construction material comprises a polymer selected from the group of: (co)polycarbonates, polyesters, polyestercarbonates, polyformals, polyamides, polyethers, polyvinylchloride, polymethyl(meth)acrylate, polystyrene or a combination of at least two of these and an additive that absorbs infrared radiation, wherein the additive that absorbs infrared radiation is present in the construction material in an amount of ≥ 0.0005% by weight to ≤ 3% by weight, based on the total weight of the construction material, wherein the additive that absorbs infrared radiation, in terms of its chemical structure and its concentration in the construction material, is selected such that it reduces the transmittance of the construction material for light in the wavelength range between 600 nm and 1700 nm, measured to ISO 13468-2, determined on a 100 μm-thick sample, by ≥ 2.5 percentage points compared to a sample of the construction material having a thickness of 100 μm that does not contain the additive that absorbs infrared radiation, and wherein, during the additive manufacturing method, the construction material is at least temporarily exposed to infrared radiation in the wavelength range between 600 nm and 1700 nm, wherein the additive that absorbs infrared radiation is present at the surface of the construction material and is not distributed within the construction material and is selected from the group of: borides, tungstates, mixtures of at least one boride and at least one tungstate, organic IR absorbers or a combination of at least two of these. wherein the construction material comprises a polymer selected from the group of: (co)polycarbonates, polyesters, polyestercarbonates, polyformals, polyamides, polyethers, polyvinylchloride, polymethyl(meth)acrylate, polystyrene or a combination of at least two of these and an additive that absorbs infrared radiation, wherein the additive that absorbs infrared radiation is present in the construction material in an amount of ≥ 0.0005% by weight to ≤ 3% by weight, based on the total weight of the construction material, wherein the additive that absorbs infrared radiation, in terms of its chemical structure and its concentration in the construction material, is selected such that it reduces the transmittance of the construction material for light in the wavelength range between 600 nm and 1700 nm, measured to ISO 13468-2, determined on a 100 μm-thick sample, by ≥ 2.5 percentage points compared to a sample of the construction material having a thickness of 100 μm that does not contain the additive that absorbs infrared radiation, and wherein, during the additive manufacturing method, the construction material is at least temporarily exposed to infrared radiation in the wavelength range between 600 nm and 1700 nm, wherein the additive that absorbs infrared radiation is present at the surface of the construction material and is not distributed within the construction material and is selected from the group of: borides, tungstates, mixtures of at least one boride and at least one tungstate, organic IR absorbers or a combination of at least two of these. <EOS>
