Abstract: 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.

Abstract: This application describes a build plate having integrally formed channels for cooling the build plate during additive manufacturing or 3D printing. The build plate may include a bottom portion (e.g., base, section, half, etc.) and a top portion (e.g., top, section, half, etc.). The top portion is formed, via additive manufacturing, onto the bottom portion. The top portion includes channels that are configured to receive coolant, gases, or other fluids to provide cooling effects to the build plate during manufacturing of a part on the build plate. The use of the channels may result in increased heat dissipation, improved throughput, precision, and/or efficiencies in additive manufacturing.
