A method for producing a dental prosthesis part by means of a 3D printer, wherein - a three-dimensional digital dental prosthesis part model is generated with the aid of a computer, taking into account a digital denture model , - the digital denture model comprises a toothed and/or untoothed region of a lower and/or upper jaw to be treated, - a load test of the dental prosthesis part model is carried out with the aid of a computer, taking into account the denture model , - a three-dimensional digital first reinforcement structure model having a first three-dimensional shape and a first position is arranged with the aid of a computer within the dental prosthesis part model , taking into account a result of the load test, and the dental prosthesis model is reduced by a volume corresponding to the arranged first reinforcement structure model , - the reduced dental prosthesis part model is divided into a lower partial volume and an upper partial volume , - the lower partial volume and the upper partial volume each adjoin the arranged first reinforcement structure model , - a lower part (10.1) of the dental prosthesis part according to the lower partial volume of the dental prosthesis part model is produced by means of the 3D printer from a first composite material, - a first reinforcement structure corresponding to the first reinforcement structure model is arranged on the lower part (10.1) of the dental prosthesis part corresponding to the first position, - an upper part (10.3) of the dental prosthesis part according to the upper partial volume of the dental prosthesis part model of the first composite material is placed by means of the 3D printer on the lower part (10.1) of the dental prosthesis part with the arranged first reinforcement structure in order to complete the dental prosthesis part . - a three-dimensional digital dental prosthesis part model is generated with the aid of a computer, taking into account a digital denture model , - the digital denture model comprises a toothed and/or untoothed region of a lower and/or upper jaw to be treated, - a load test of the dental prosthesis part model is carried out with the aid of a computer, taking into account the denture model , - a three-dimensional digital first reinforcement structure model having a first three-dimensional shape and a first position is arranged with the aid of a computer within the dental prosthesis part model , taking into account a result of the load test, and the dental prosthesis model is reduced by a volume corresponding to the arranged first reinforcement structure model , - the reduced dental prosthesis part model is divided into a lower partial volume and an upper partial volume , - the lower partial volume and the upper partial volume each adjoin the arranged first reinforcement structure model , - a lower part (10.1) of the dental prosthesis part according to the lower partial volume of the dental prosthesis part model is produced by means of the 3D printer from a first composite material, - a first reinforcement structure corresponding to the first reinforcement structure model is arranged on the lower part (10.1) of the dental prosthesis part corresponding to the first position, - an upper part (10.3) of the dental prosthesis part according to the upper partial volume of the dental prosthesis part model of the first composite material is placed by means of the 3D printer on the lower part (10.1) of the dental prosthesis part with the arranged first reinforcement structure in order to complete the dental prosthesis part . <EOS>
