Title: 3D MANUFACTURING USING MULTIPLE MATERIAL DEPOSITION AND/OR FUSION SOURCES SIMULTANEOUSLY WITH SINGLE OR MULTI-FLUTE HELICAL BUILD SURFACES
Abstract:
Disclosed herein is a method and apparatus to improve the speed of the free-form manufacture of complex systems using the helical build process to 3D print / manufacture objects by using multiple material fusion sources simultaneously with single- or multi-flute helical build surfaces. As a result of the stationary material deposition line in a helical build machine, the speed of the fusion process can be improved by simultaneously using multiple fusion in sources in parallel on each fusion line. The geometry of the fixed location of the fusion line allows for changes in the optics of laser based machines which may lead to improvements in speed of over 100x compared to the speed of a single flute machines. Speed improvements are possible for all types additive manufacturing processes that use the helical build approach.
