The invention relates to a 3D printing method for producing a multi-material mixture of objects (30, 36), to a 3D printing manufacturing apparatus (10), and to objects (30, 36) produced by means of said method and manufacturing apparatus (10). According to the invention, the 3D printing method for producing a multi-material mixture of objects (30, 36) is provided, said method comprising the stepsof providing salt powder and metal powder and providing a 3D printing manufacturing apparatus (10); activiating the 3D printing manufacturing apparatus (10), wherein the salt powder and the metal powder are co-processed in the 3D printing manufacturing apparatus (10) in order to produce an object (30, 36) having a user-defined mixing ratio between the salt powder and the metal powder, the proportion of the salt powder being 10-40% or 50-80%. The invention further relates to the 3D printing manufacturing apparatus (10). An object (30, 36) produced in this manner is also proposed. 本发明涉及一种用于制造物件(30、36)的多材料混合物的3D打印方法以及3D打
