Many high precision engineering applications require deep channels that have very sharp corners.  This is a difficult feature to create using CNC machining, typically requiring multiple iterations of plunge EDM.  With Fabrisonics’s hybrid additive/subtractive 3D printing technology, the problem becomes much simpler.  In a hybrid system, such as our SonicLayer 7200, sharp corners can be machined as the part grows in Z.  As each layer is welded, the CNC head can come in and machine the corner with a small end mill (for instance .005” diameter).  Although these ultrafine end mills are typically very short,  you can machine the corners out in stages since you are only building .005-.010” per layer.  Thus a feature with sharp corners can be printed several inches deep.
