PRECIPRINT 3D

By using serial tools for the production of prototypes we can save your time The prototype pieces are the key for the efficient serial production. This is why we pay a lot of intention to all prototype processes as well as all processes before the serial production. This phase is intended for taking down all data and information which are vital for the implementation in the serial production. Based on the foreseen technology, which is the result of experience and data from the simulation equipment, we produce serial production tools for the production of prototype pieces in our company. Because we use serial tools for prototype production, we do not need additional time and special adjustments to transition to classic serial production. This gives us the advantage of being able to offer serial production within the shortest possible timeframe.

• Mold measurements up to 4 x 2 x 1 m • Does away with elaborate and expensive mold set-ups • Short throughput time (a few days) • Sand molds correspond 1:1 with CAD model • Structures can be designed in accordance with requirements, without having to watch for draft angles or undercuts • Special sands prevent casting problems • Surface quality can be adjusted through use of different sands • Coarse-grained sands for high gas permeability • Considerable flexibility with changes in geometry, without additional expenses • No storage or maintenance of patterns • Cost savings particularly for complex molds and batch sizes of 1 to several hundred pieces

The VX4000 is the world's biggest industrial 3D printing system for sand molds. It has a cohesive build space measuring 4,000 x 2,000 x 1,000 mm (LxWxH). This machine can be used to economically produce very large individual molds, a great many small series components or a combination of the two. With its uniquely large volume, the VX4000 maximizes productivity and flexibility. The unique and patented layering process was specially adapted for this printer. Instead of lowering the building platform during the printing process, the print head and coater are raised with each layer. As a result, the machine can bear the enormous weight of the building platform, which can be quickly exchanged via a rail—making it possible to print nearly continuously. Sand can be used as the particulate material. The VX4000's print head system can achieve a resolution of up to 300 dpi. A layer applied in one cycle is 300 µm thick.
