METHOD AND DEVICE FOR PRODUCING THREE-DIMENSIONAL MODELS
First Claim
1. A method for producing three-dimensional components based on computer data by repeated application in layers of a medium containing particulate material and selective solidification of the medium, whereby a feedstock made of the medium in a build space is provided and a layer application of the medium by means of a coating unit takes place on a surface of the feedstock bordering the build space at an angle β
- and a solidification according to computer data occurs by use of a solidification unit, characterized in that the feedstock is not moved during build-up of the object, preferablycharacterized in that the coating unit and/or solidification unit has an angle of α
<
90°
to the build plane of the build space and are moved in relation to the feedstock.
