3D printing for the pump and heavy industry

3D printing has proven itself both in the development departments and the procurement of spare parts in the pump and heavy industry. The technology shows its advantages especially regarding mold assembly and accuracy. The clear advantage of 3D printing is that instead of printing the entire mold, only the complex cores can be printed and integrated into conventionally manufactured top and bottom boxes. This eliminates, among other things, core marks or core offsets.

Usually the best solution: the combination of conventionally produced molds and complex, 3D-printed cores - for example impeller cores. This allows a cost-efficient production and development. This results in medium-sized series of Francis impellers or single large-volume impellers. The size and speed of voxeljet's 3D printing systems simplify both.

Possible applications are Francis impellers, Pelton turbines or radial impellers.
