First Claim
Patent Images
1. A method for producing a component, wherein the component is a 3D molded body, comprising the steps of:
- (a) applying a particle layer to a building platform in a first step with the aid of a powder coater;
(b) selectively applying a binder in a second step with the aid of a dosing device;
(c) subjecting the applied layer or layers to a heat treatment in another step with the aid of a heat source;
(d) lowering the building platform by the thickness of one layer, or raising the powder coater by the thickness of one layer;
wherein steps a) through d) are repeated until the component is built up, and the heat treatment (c) carried out after every second or additional layer application step.
