Metal Matrix Composites by 3D Printing Goal: To fabricate ceramic preforms for metal matrix composites. 3D Printing is used to create the preforms and thereby to define the shape of the final part. Pressure infiltration is used by Metal Matrix Cast Composites to create the composite. Approach: Sponsor: Metal Matrix Cast Composites, Inc. ...more to come...
