An additive manufacturing system including a two-dimensional energy patterning system for imaging a powder bed is disclosed. The two-dimensional energy patterning system may be used to control the rate of cooling experienced by each successive additive layer. Accordingly, the system may be used to heat treat the various additive layers.

Some variations provide a method of making a nanofunctionalized metal powder, comprising: providing metal particles containing metals selected from iron, nickel, copper, titanium, magnesium, zinc, silicon, lithium, silver, chromium, manganese, vanadium, bismuth, gallium, or lead; providing nanoparticles selected from zirconium, tantalum, niobium, or titanium; disposing the nanoparticles onto surfaces of the metal particles, in the presence of mixing media, thereby generating nanofunctionalized metal particles; and isolating and recovering the nanofunctionalized metal particles as a nanofunctionalized metal powder. Some variations provide a composition comprising a nanofunctionalized metal powder, the composition comprising metal particles and nanoparticles containing one or more elements selected from the group consisting of zirconium, tantalum, niobium, titanium, and oxides, nitrides, hydrides, carbides, or borides thereof, or combinations of the foregoing.

A control system for a three-dimensional printer includes an energy component interface, an agent depositing component interface, and control logic. The control logic controls the operation of an energy component through the energy component interface and an agent depositing component through the agent depositing component, in forming an output object that is specified in a print job. Additionally, in some examples, the control logic can implement a plurality of modes. Each mode, when selected modulate one or more operational parameters of a least one of the energy component or agent depositing component.

An additive manufacturing device includes a recoater configured to push powder onto a build platform. The recoater defines an advancing direction for pushing powder. A first baffle is mounted to a first end of a leading edge of the recoater and a second baffle mounted to a second end of the leading edge of the recoater opposite the first end. Each of the first and second baffles includes a base mounted to the recoater, a first wall that extends obliquely ahead of and laterally outward from the base relative to the advancing direction, and a second wall opposite the first wall. The second wall extends obliquely ahead of and laterally inward from the base relative to the advancing direction. A volume is defined between the first and second wall with capacity to collect powder as the recoater advances.

Provided is a method for manufacturing material powder for metal laminating modelling, in which a virgin material is manufactured based on the particle size distribution of the virgin material being an unused material powder, and the fluidity of an unsintered reused material after the virgin material is reused a predetermined number of times by a metal laminating modelling device, so that the particle size distribution of the virgin material corresponds to the fluidity of the reused material that is equal to or greater than a predetermined standard value. Silica particles may be added to the virgin material.
