A spatter protection system for an additive manufacturing machine can include a sheet configured to be disposed over a build area of the additive manufacturing machine. The sheet can include an aperture configured to allow a spatter from the build area to eject through the aperture during energy application and to land on a back side of the sheet to prevent the spatter from landing on the build area. The system can include a motive system supporting the sheet and configured to move the sheet to locate the aperture over an energy application area.

A machine (10) for additive manufacturing by powder bed deposition comprises a work surface (12), a device (16) for selective consolidation, a device (18) for extracting the fumes, the selective consolidation device emitting at least two beams (F1, F2) of energy or heat. The work surface is divided into at least two work zones (Z1, Z2) adjacent to one another, and a first beam (F1) consolidates the powder in a first work zone (Z1) and a second beam (F2) consolidates the powder in a second work zone (Z2). The fume extraction device (18) comprises at least one central gas suction and/or gas blowing manifold (40) which is mounted to be translationally movable above an overlap zone (ZR) of the different adjacent work zones, and two side gas suction and/or gas blowing manifolds (42, 44) which are fixedly mounted and arranged on either side of the work surface, whcrcin the central manifold (40) extends at least over a maximum dimension of the work surface.

A laser-solid-forming manufacturing device includes a laser emitter, a magnetic field generator, and a forming platform. The laser emitter emits a laser beam which acts on a feedstock to form a molten pool. The magnetic field generator includes a spiral copper coil, a first electrode and a second electrode. The spiral copper coil is formed by spirally winding a copper tube. The first and second electrodes are arranged at respective ends of the copper tube and are used for loading a voltage to generate a magnetic field in the spiral copper coil. At any time, the spiral copper coil sleeves an action point of the laser beam and the feedstock. A corresponding laser-solid-forming manufacturing method is also presented.

An additive manufacturing system configured to additively build an article can include an energy applicator, a build platform, and a powder nozzle configured to eject powder toward the build platform to be acted on by the energy applicator. The system can include a control module configured to control the energy applicator to create an amorphous structure forming at least a portion of the article.

An integrated box-type 3D printing device, having a support structure, a first bracket, a second bracket, and a printer body. The first bracket is movable back and forth in a first direction on the support structure. The printer body is arranged on the second bracket. The second bracket is movable back and forth in a second direction relative to the first bracket. The printer body is movable back and forth in a third direction on the second bracket. The support structure is provided with an accommodating space for accommodating the second bracket. The second bracket is foldable in the opposite direction to the third direction so that the second bracket is foldable into the accommodating space so that the integrated box-type 3D printing device assumes a transport and storage configuration when the second bracket is folded into the accommodating space.
