1. A method for 3D printing comprising the steps of:
- i) depositing a build layer including one or more build materials on a build platform, wherein the build materials includes a particulate material and the build layer has a height;
ii) lowering the build platform; and
iii) repeating steps i) and ii) to print a 3D object;
wherein the step of lowering the build platform includes a step of vertically driving one or more Z-axis drive units connected to a horizontal drive component for moving the horizontal drive component in a vertical direction;
wherein a horizontal guide component is supported by the horizontal drive component, positioned above the horizontal drive component, and is vertically displaced by the moving of the horizontal drive component;
wherein the guide component is free to move horizontally relative to horizontal drive component; and
wherein the build platform is the horizontal guide component or the build platform is supported by the horizontal guide component and connected to the horizontal guide component.

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.
