Abstract

A method for the manufacturing of parts, especially molds or cores, by a deposition technique, comprising the steps of: depositing a layer of a pourable composite material containing particles with a binder material coating, into a process area of a defined length and width fitting to the dimensions of a part to be manufactured; applying a moderating agent onto said composite material layer in a selective sub-area of said process area; inducing energy to solidify said selective sub-area, respectively the area of said process area void of said moderating agent; repeating the aforementioned steps; and separating of solidified composite material from non-solidified composite material.
