Abstract
The present invention relates to a device for manufacture of three-dimensional models by means of a 3D printing process, whereby a spreader device is used to deposit particulate material in layers on a build platform and the particulate material flow, which occurs perpendicular to the spreading direction, is transferred into containers that are actively cleaned by sliders or brushes at the spreader device. It exploits the fact that particulate material that is moves dynamically can only bridge small height differences. The arrangement can be implemented in a space-saving manner beneath the spreading plane.
