Abstract
Official abstract text for this publication.
A method of additively manufacturing parts by selectively cooling a liquefied thermoplastic material.
First claim
Opening claim text (preview).
The invention claimed is: 1. An additive manufacturing device comprising: a build tray with an array of heat exchange elements each of which are configured to independently and alternately heat and cool a respective area of the build tray; a moveable platen that lowers and raises into the build tray; a heated re-coater body moveably mounted between said build tray and said moveable platen and configured to apply successive layers of thermoplastic material to said build tray; said successive layers of thermoplastic material alternately solidified by the heat exchange elements of the build tray by cooling said thermoplastic material to create each layer of a multilayer part and then partially liquefied to release solidified thermoplastic material from the build tray as the moveable platen moves out of the build tray. 2. The additive manufacturing device of claim 1 configured to operate in any orientation, with or without the force of gravity. 3. The additive manufacturing device of claim 2 comprising a second liquefied thermosetting compound. 4. The additive manufacturing device of claim 1 wherein the heat exchange elements are Peltier hot/cold junctions. 5. The additive manufacturing device of claim 1 wherein the moveable platen is configured to be heated or cooled. 6. The additive manufacturing device of claim 1 further comprising a temperature controlled enclosure surrounding the build tray and moveable platen.
