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, said movement provided by at least two vertical positioning units on the support frame. In this respect, it is provided that the positioning units are respectively separate components and are arrangeable on the support frame independently from one another and the location and orientation of such can be adjusted independently from one another.

1. A method for assembling an apparatus for manufacturing three-dimensional models by means of a 3D printing process comprising: arranging at least two vertical positioning units on a common substrate, wherein each vertical positioning unit has a drive direction and each vertical positioning unit has adjustable feet;independently adjusting an angle of each of the vertical positioning units by adjusting one or more of the feet so that the drive direction of each vertical positioning unit is in a vertical direction;attaching one of the vertical positioning units to a first side of a support frame after the step of adjusting the angle of said vertical positioning units; andattaching a different one of the vertical positioning units to a second side of the support frame after the step of adjusting the angle of said vertical positioning units, wherein the first and second sides are opposing sides of the support frame;wherein the support frame supports one or more material deposition units and is arranged around a build platform having a base surface for building the 3-D model; the support frame is moveable in a vertical direction by the vertical positioning units; andthe base surface of the build platform is perpendicular to the vertical direction. 2. The method of claim 1, wherein the one or more material deposition units includes a coater for depositing a particulate material. 3. The method of claim 2, wherein the one or more material deposition units includes a print head for applying a binder material. 4. The method of claim 1, wherein the at least two vertical positioning units includes a first pair of vertical positioning units and a second pair of vertical positioning units, wherein the first pair of vertical position units are placed along a first line and the second pair of vertical positioning units are placed along a second line, wherein the first line and the second line are parallel. 5. The method of claim 4, wherein three vertical positioning units including the first pair of vertical positioning units are placed along the first line and three vertical positioning units including the second pair of vertical positioning units are placed along the second line. 6. The method of claim 1, wherein each vertical positioning unit has at least three vertically adjustable feet and the step of adjusting the angle includes adjusting one or more of the feet. 7. The method of claim 1, wherein at least two of the vertical positioning units are connected by a flexibly deformable supporting structure is flexibly deformable. 8. The method of claim 1, wherein each of the vertical positioning units includes a drive motor. 9. The method of claim 8, wherein the drive motors are coupled with each other via an electronic gantry system. 10. The method of claim 1, wherein the at least two vertical positioning units includes a first pair of vertical positioning units and a second pair of vertical positioning units, wherein the first pair of vertical positioning units are positioned in spaced apart locations on a first linear track and the second pair of vertical positioning units are positioned in spaced apart locations on a second linear track. 11. The method of claim 10, wherein the first linear track is angled relative to a horizontal plane and/or the second linear track is angled relative to a horizontal plane. 12.

The method of claim 16, wherein each vertical position unit is adjusted prior to attaching to the support frame. 18. The method of claim 1, wherein the apparatus is free of any frame structure above the support frame and is free of vertical walls surrounding the build platform. 19. The method of claim 1, wherein the vertical positioning units are connected only by the support frame. 20. A method for assembling an apparatus for manufacturing three-dimensional models by means of a 3D printing process comprising: arranging at least i) a first pair of vertical positioning units and ii) a second pair of vertical positioning units on a common substrate, wherein each vertical positioning unit has adjustable feet and has a vertical drive direction;independently adjusting an angle of each of the vertical positioning units by adjusting one or more of the feet so that the drive direction of each vertical positioning unit is in a vertical direction;attaching the first pair of vertical positioning units to a first side of a support frame; andattaching the second pair of vertical positioning units to a second side of the support frame, wherein the first and second sides are opposing sides of the support frame;wherein each vertical positioning unit is attached to a location of the support frame other than a corner of support frame supports one or more material deposition units and, the support frame is arranged around a build platform having a base surface for building the 3-D model; and the support frame is moveable in a vertical direction by the vertical positioning units wherein the one or more material deposition units include a coater or a print head. 21. A method for manufacturing three-dimensional models by means of a 3D printing process comprising steps of: arranging at least two vertical displacement units,wherein each vertical displacement unit has adjustable feed for independently adjusting an angle of each of the vertical displacement units so that a drive direction of each vertical displacement unit is in a vertical direction;applying construction material in layers on a construction platform including applying a particulate material with a metering device; wherein the metering device and a solidifying means for solidifying the particulate material are mounted to a support frame via longitudinal guides, wherein the support frame is arranged around the construction platform; andraising the support frame with the vertical displacement units; wherein the vertical displacement units move the support frame in a Z-direction substantially perpendicular to a base of the construction platform, the vertical displacement units are provided on the support frame;wherein the vertical displacement units each constitute a separate part, are each independently disposable on the support frame, and are each independently adjustable in position and direction.
