Abstract

An additive printing method depositing a functional print pattern on a surface of a 3D object, an associated computer program, and a computer-readable medium storing the program. The method comprises as steps (i) providing the object on a planar surface; (ii) providing a print head having print nozzles defining a plane non-parallel to the planar surface; (iii) generating 3D geometrical surface data of an exposed surface of the object on the planar surface; (iv) generating 2D geometrical surface data of the exposed surface on the basis of the 3D geometrical surface data; (v) determining an amount of printing fluid to be discharged at a discharge time from each of the print nozzles; (vi) generating a relative movement between the object and the print head; and (vii) printing a print pattern on at least one portion of the exposed surface during the relative movement. A step of correcting data is included.
