ABSTRACT OF THE DISCLOSURE A method for forming a three-dimensional object by applying segments of complementary material and deposition material so as to form layers of material. Selected segments of material are then shaped after one or more segment is formed. In this manner, layers of material form a block containing the object made of deposition material and surrounded by complementary material. Then, the complementary material which serves as a support structure during forming is removed. Preferably, the complementary material has a lower melting temperature than the deposition material and is removed by heating the block. The deposition material and complementary material are preferably applied by thermal spray deposition but may be applied by weld deposition, liquid slurry, gravity drop or any manual means such as a hand sifter. It is also preferred but not necessary to use masks when applying the material.
