Abstract
The present disclosure provides a method for fabricating a mixed-material 3D object, including forming, based on layer-print data of a target object, a layer-print product by one-by-one printing a plurality of pixels, using N0 types of main materials for the target object; forming a plurality of the layer-print products by repeatedly forming the layer-print product; and forming a mixed-material 3D object by stacking one of the layer-print products on another. Each of the plurality of pixels is printed by N1 types of the main materials and N2 types of auxiliary materials, N1≤N0, and when N1<N0, N2≥1, and each of the plurality of pixels is formed by ejecting a plurality of ink droplets.
