LAMINATE SHAPING METHOD

A laminate shaping method includes: a unit step repeatedly performed, the unit step including a step of forming a laminate shaped portion by laminating metal layers formed of weld beads, and a step of forming a processed side surface by cutting a shaped portion side surface facing a second direction intersecting a first direction, in which, in the step of forming the processed side surface, the shaped portion side surface is cut so that a receiving portion projecting in the second direction with respect to the processed side surface is formed at an uppermost layer of the laminate shaped portion in the first direction, and when the unit step is repeated, in the step of forming the laminate shaped portion, a new metal layer is laminated so as to overlap an upper surface of the receiving portion in the first direction.

DRYING DURING ADDITIVE AND SUBTRACTIVE MANUFACTURING
20220331873 · 2022-10-20 ·

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.
