The present invention relates to a device for manufacturing three-dimensional models by means of a 3D printing process, whereby a build platform for application of build material is provided and a support frame is arranged around the build platform, to which said support frame at least one device for dosing the particulate material and one device for bonding the particulate material is attached via the guiding elements and the support frame is moveable in a Z direction, which essentially means perpendicular to the base surface of the build platform. In so doing, the device provides a material feeding device having a particle material container to supply particulate material in batches from the storage area to the dosing apparatus and to do so with the least possible amount of shearing forces and without significant interaction with the atmosphere.
