Abstract

The present invention relates to a device for manufacture of three-dimensional models by means of a 3D printing process, whereby the build material is deposited on a build platform in layers and the build platform is moveable in the Z-direction and one or several drive units and one or several guide elements is/are provided to move the build platform. In so doing, drive units and guiding elements are arranged in such a way that a movement of the drive units is decoupled from the movement of the guiding elements.
