Abstract: A method of altering an additively manufactured part can include orienting a surface of the additively manufactured part toward a rotational center that may be independent of a rotational axis defined by the additively manufactured part, flowing an abrasive media past the surface, rotating the additively manufacturing part about the rotational center; urging abrasive particles in the abrasive media past the surface abrasive media to impinge the surface with centrifugal force generated by the rotating, and improving surface finish of the surface.

Abstract: A method for producing a device having at least one internal feature includes manufacturing an internal volume of the internal features out of a first material, disposing the internal volume in a parent material that has a higher melting point than the first material, causing the internal volume to melt within the parent material, and allowing at least a portion of the first material to diffuse into the parent material, thereby leaving behind the at least one internal feature within the parent material.

Abstract: A support structure for an additive manufacturing system includes a support body with a support body material and an interface disposed on the support body with an interface material. The interface material has a ductile-to-brittle transition temperature that is higher than the ductile-to-brittle temperature of the support body material for selectively fracturing the interface material to separate an additively manufactured article from the support body.

Abstract: An additive manufacturing system includes a build platform and an illuminator disposed on opposite sides of a powder carrier relative to gravity. The powder carrier has a movement envelop that intersects the beam path and includes a material that is translucent to radiation emitted by the illuminator such that the emitted radiation traverses the powder carrier and fuses powder from a powder bed carried by the powder carrier with a substrate overlying the powder carrier and suspended from the build platform.

Abstract: A method for selecting an alloy for additive manufacturing includes melting a first material and a second material together to create a material melt, spinning the material melt to create melt spun ribbons, welding the ribbons together to produce a weld, and determining a weld quality of the weld.

Abstract: A feedstock for a cold spray process includes a plurality of globule bodies. The globule bodies include a plurality of discrete particles bonded to one another to define porous globule bodies. The bonds between the particles are of sufficient strength such that the globule bodies can retain both the body integrity as well as the body shape when the body experiences acceleration from a conveying gas in a cold spray technique. Methods of making the feedstock and globule bodies are also described.
