A method for three-dimensional color printing and a three-dimensional color printing device

摘要

A method and device for three-dimensional colour printing is disclosed in which at least a first printing material with a first printing material colour and at least another printing material with another printing material colour are used to construct a printing object 7. An arrangement of the printing materials in a surface region and a near surface interior region of the printing object 7 is determined based on a desired colour reproduction of the printing object 7 and for each voxel of the surface region and the near surface interior region: a printing material colour vector is assigned to the voxel, a printing material sequence vector is determined depending on the printing material colour vector, one printing material of the printing material sequence vector is selected depending on a distance of the voxel to its respective closest surface voxel and the selected printing material is assigned to the voxel.
