摘要： Systems, devices, and methods according to the present disclosure are configured for use in additive manufacturing. Systems for additive manufacturing can include stand-alone manufacturing units, a series of units on an assembly line, or a high-capacity system with workflow automation features including a conveyor for transporting parts to or from a build area, or a robotic arm for transporting parts or adjusting a system component. An additive manufacturing system (100) can include a flow regulator (130) to change a temperature of a thermoplastic material at or in a tip (150) of a material extrusion nozzle cartridge (171), such as to enable or inhibit flow of the thermoplastic material from the tip. The flow regulator can be configured to provide a specified gas or liquid at a specified temperature, velocity, or volume.

摘要： An automated additive manufacturing system can optionally include a conveyable build sheet (185). A part removal device (211) can be positioned in proximity to a surface of the build sheet to facilitate separating a part composite (281) from the build sheet. The build sheet can optionally include a turn or fold at which a part composite can be detached from the build sheet. A conveyor including a part composite can be moved through a solvent area having a solvent that is configured to dissolve or separate a support material from a model material in a part composite. A sorting device can be configured to identify characteristics of different part composites, and in response, direct selected ones of the parts to different receiving areas in the system. The system can include a drying device to dry a part composite using an airflow.
