Powder Deposition and Sintering for a Two-Powder Approach to Solid Freeform Fabrication [PDF]

open access: yes, 1998
A two-powder approach is presented where Fused Deposition modeling (FDM) is used to create a thin shell in the shape of the part to be fabricated. The shell is filled with powder of the part material and surrounded by a support powder that has a high ...
