First Claim
Patent Images
1. A method for producing one or more three-dimensional components based on computer data comprising steps of:
- repeatedly applying layers, including sequential layers, of a medium containing a particulate material with a coating unit on a build surface of a feedstock made of the medium;
selectively solidifying the medium with a solidification unit,wherein the feedstock is supported by a support surface, and the build surface has a build angle, α
, relative to the support surface, wherein the build angle is an acute angle greater than 0 degrees; and
wherein the feedstock is stationary during application of sequential layers of the medium;
wherein the coating unit moves on a coordinate system placed at the build angle, angle α
, relative to the support surface while applying one of the layers; and
wherein the coating unit moves in a direction parallel to the support surface between the sequential layers.

Abstract
The present invention relates to a method for producing three-dimensional objects 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 medium in a build space is provided and a layer application of the medium 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.
