Abstract: A method and apparatus for forming three-dimensional objects by laser sintering that includes the use of dense phase pneumatic conveying to internally recycle overflow powder, and to thoroughly blend overflow, recovered (266) and virgin powder to provide a consistent powder feed mix to a laser sintering machine (252). Overflow powder from the laser sintering machine is recovered and recycled back into the laser sintering machine (252) for reuse. The approach results in a compact and reliable powder recycle system with complete blending and minimum attrition to the handled powder.
