The VX4000 from voxeljet technology GmbH is a large-format 3D printing system
for research, design, short-run manufacturing, architecture, and automotive applications requiring
oversized objects.
The system has a resolution of 42.3 µm by 42.3 µm, an accuracy of <0.3%, and printing speeds of
6.5 mm/hr. It can produce prototypes measuring 4000 mm by 2000 mm by 1000 mm with layer
thicknesses of 120 µm.
The printing system produces objects from polymethyl methacrylate (PMMA) particle material.
Using 3D CAD data, the system applies thin layers of particle material repeatedly to a building
platform in a build-up process. The layers are bonded together with fluid binder according to the
layer geometry. The building volume of 4 m by 2 m by 1 m is about eight times the volume of
conventional 3D printing systems. The equipment costs $2.3 million with an annual operation cost,
including depreciation, of $1.44 million. Materials represent 60% of the overall operating
cost.
The system accepts STL, IGES, and STEP input files.
