Zusammenfassung:	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.
