Our Mission

We solve problems! We can remedy a multitude of production issues faced by traditional metal casting foundries and fabrication houses.


By creating an integrated system that produces large complex parts from multiple metallic materials, +Mfg delivers a practical approach to production more than any existing method to create a 3D part.

The parts can be made cost effectively in prototype to production quantities while eliminating traditional production issues.
