A tool and die set and related method of use of the tool and die set in a press for the compaction of a powder metal into a preform involves an uneven amount of positional deflection of at least two lower or upper tool members. This asymmetrical elastic response under load may help to eliminate cracking of the part after the compressive load is removed.

A system for monitored additive manufacturing of an object, comprising a manufacturing unit], designed for additive manufacturing of the object based on metal-containing manufacturing material in a manufacturing volume, wherein the object is built up by repeated layer-by-layer provision of the manufacturing material in defined quantity and accurately-positioned forming of the provided manufacturing material.

Disclosed are systems, devices, and methods for additive manufacturing that allow for control of composition and/or porosity of components being manufactured. More particularly, in exemplary embodiments, a secondary material can be used in conjunction with a primary feedstock material in a spatially controlled manner during an additive manufacturing process to control a composition of materials and/or porosity of a manufactured component. Systems, devices, and methods for additive manufacturing are also disclosed that allow for control of a pressure of an atmosphere surrounding a build surface during an additive manufacturing process. More particularly, a pressure of an atmosphere surrounding a build surface can be raised to a pressure greater than standard atmospheric pressure. Various features of the exemplary embodiments of the systems, devices, and methods disclosed can be used together to further control for composition and/or porosity and quality of a manufactured part.
