Calculable three-dimensional color printing method

A calculable 3D color printing method, comprising:

• (1) device initialization:
• fixing an 3D object at an end of a device capable of lifting and lowering at a constant speed;
• and calculating a position and an orientation of the object relative to a PVA film using a 3D vision system, namely obtaining a 3D model of the 3D object;
• (2) virtual simulation:
• performing simulated calculation with respect to a motion of the PVA film while the 3D object is being lowered at a constant speed;
• (3) calculating texture pattern on the PVA film:
• calculating a corresponding relationship between each pixel on the PVA film and an object surface point by the virtual simulation;
• and obtaining a texture pattern on the PVA film by assigning a color on the object surface point to the pixel on the PVA film;
• (4) physical printing:
• printing the texture pattern obtained by the calculating at step (3) onto the PVA film;
• arranging the PVA film onto water surface at a fixed location;
• and performing water transfer printing and coloring;
• and
• (5) multiple printing:
• performing water transfer printing operations from varied angles for an object having complex surface geometry, wherein only a portion of the object surface is colored each time, until the entire object surface is colored.
