Pump and Heavy Industry

3D printing has been tried and tested in the development departments and in the procurement of spare parts in the pump business and heavy industry. The advantages of the technology can be seen mainly in assembly and in accuracy. Clear benefit of 3D printing: Cores can be joined together or integrated into top or bottom boxes, which eliminates core prints and core offsets, among other things.

A hybrid approach consisting of conventionally produced molds and complex, 3D-printed cores—e.g., impeller cores—is usually the best solution in order to produce or develop products cost-efficiently. Medium-sized series of Francis impellers and large-volume impellers are created—they can both be represented without problems, due to the size and speed of the voxeljet 3D printing systems.
