A 3D printing system uses heat sources, such as lasers, for manufacturing parts in metal additive manufacturing, such as powder-bed fusion, on one or more movable build modules. The build modules may be moved (e.g., by a conveyor system) into and out of a lasing module. Parts may be manufactured on multiple build modules simultaneously and/or sequentially, in some cases while the build module(s) are moving relative to the heat sources. Sensor(s) are arranged to determine a position, orientation, and/or movement of the build modules and feedback from the sensor(s) may be used to control the heat sources to compensate for motion of the build modules.

The spinning mechanism includes a machine tool and a spinning head. The spinning head is installed on the machine tool by a main shaft, and the main shaft is configured to drive the spinning head to rotate to achieve the movement in three vertical directions. The spinning head includes a spinning base and balls. Each of the balls is installed in a corresponding one of arc grooves at a bottom of the spinning base. The fused deposition modeling mechanism includes a moving track, a robot and a heat source generator. The arc moving track is arranged around the machine tool in a surrounding mode. The robot is movably installed on the moving track. The heat source generator is installed at a tail end of the robot.

A device for the stereolithographic additive manufacturing of metallic components includes a material support for a material layer of a material to be polymerized, the surface of which forms a building plane, a material container for fresh material, which opens into the building plane via a material feed opening, a build platform movable between a position flush with the building plane and a lowered position perpendicular to the building plane, a doctor blade movable between the material container and the build platform for applying the material layer on the building plane, and an exposure unit for position-selective exposure of the material layer on the build platform or on a component partially built on the build platform. The material support is exchangeably arranged in the device.

Complexity of a geometry of a desired (i.e., target) three-dimensional (3D) object being produced by an additive manufacturing system, as well as atypical behavior of the processes employed by such a system, pose challenges for producing a final version of the desired 3D object with fidelity relative to the desired object. An example embodiment enables such challenges to be overcome as a function of feedback to enable the final version to be produced with fidelity. The feedback may be at least one value that is associated with at least one characteristic of a printed object following processing of the printed object. Such feedback may be obtained as part of a calibration process of the 3D printing system or as part of an operational process of the 3D printing system.

A curable resin or adhesive composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and at least one energy converting material, preferably a phosphor, capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

The shielding device may include a shielding band, and the shielding band may be coupled for movement with the coating element assembly group. The shielding band may be guided movably along a plurality of supporting points that define an interior region of the second working plane area, and the guiding device may be arranged or formed above the first working plane area.
