A data generating method is implemented by a computing system for three-dimensional (3D) printing, and includes the steps of receiving a 3D graphic file and a printing profile containing printing parameters associated with 3D printing for the 3D graphic file; recording a correspondence between the 3D graphic file and the printing profile; and combining the 3D graphic file and the printing profile according to the recorded correspondence to generate a printing data file.

The invention relates to a method for producing bone treatment means, with a first step in which original 3D data of a bone or of a bone portion of a specific patient to be treated are made available, wherein a site to be treated is present inside the bone or the bone portion, with a second step involving the use of 3D data of a reference patient who has been selected according to predefined criteria, wherein the 3D data correspond to the bone or to the bone portion with the site to be treated, and with a third and reconstructive step for supplementing or completing 3D data for the reconstruction of the site to be treated, wherein a mirroring step is used in which 3D data of the specific patient to be treated, which have their origin on a mirror-symmetrical other side of the patient, are superposed, specifically at a site corresponding to the bone or bone portion, in order to obtain the combined 3D data.
