Abstract
The invention relates to a 3D printing method and, in particular, a device and a method for setting an overfeed.
Claims19
A device for producing three-dimensional components, comprising:
- prior to producing the three-dimensional components, a build container having a build space;
- a coating unit which includes a scraper apparatus, wherein the coating unit passes over the build container and applies a particulate material in layers;
- a selective solidification apparatus;
- and
- at least one sensor for directly measuring an overfeed of the particulate material over an edge of the build space;
- wherein the sensor is provided at an end of a coating path of the coating unit;
- and the overfeed is measured at the end of the coating path after the layer of the particulate material has been deposited onto the build space.

- prior to producing the three-dimensional components, a build container having a build space;
- a coating unit which includes a scraper apparatus for providing a particulate material in layers;
- a selective solidification apparatus;
- and
- at least one sensor for measuring a weight or load of an overfeed of the particulate material;
