3D Printed Porous Polymer

Mott is the world leader in gradient structure and controlled-porosity additive manufacturing. We’ve expanded into polymer 3D printing to offer complex component designs produced completely in one print, even at high-pressure ratings. With our patent pending process, Mott can help you create custom parts with features and performance capabilities never before possible.
