Transformation steps including drying are incorporated into a process of additive manufacturing of a part. Processes and devices for achieving a transformation are described. A cycle of manufacturing is begun by adding a feedstock such as a metal paste to form a partial part followed by a transformation of the added feedstock, such as removing solvent from a metal paste, to form a transformed part suitable for a manipulation step such as machining. Inclusion of a manipulation process such as machining comprises a single cycle of a manufacturing process. One or more said cycles comprise the process of producing a completed part suitable for further processing such as sintering in the case of a metal paste feedstock to form a finished part.

A method for manufacturing a three-dimensional shaped object includes a structure shaping step of supplying a shaping material including metal powder or ceramic powder, and supplying a binder to a region corresponding to a structure S of the three-dimensional shaped object to be shaped in the shaping material (step S140), a support shaping step of shaping, with a support material including a resin, a support T supporting the structure S (step S130), and a degreasing step of degreasing the support T and the binder, the support T being in a state of supporting the structure S (step S200).

An additive manufacturing system with a build chamber has a halide vessel that generates a halide gas and a dissociation chamber with a filament. Metal condensate is contacted with the halide gas to form a gaseous metal halide compound. The gaseous metal halide compound is decomposed to deposit metal on the filament. In an example, titanium reacts with gaseous iodine to form gaseous titanium tetraiodide.
