A system is disclosed for additively manufacturing an object. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include an outlet configured to discharge a material, a leading device, and a trailing device pivotally connected to the leading device. The leading device may be configured to engage and move over the material after discharge. The trailing device may be configured to engage and move over the material at a location trailing the leading device.

The present invention relates to formulations for use in 3-D printing using radiation from visual display screens. The formulations comprise titanocene photoinitators and co-initiators. The invention also relates to methods of forming 3-D objects using said formulations.

An additive manufacturing apparatus may include a process chamber, a coating device, a shielding device, and a guiding device. The process chamber may include first and second working plane areas. The first working plane area may include a construction plane, and the second working plane area may house at least a part of the guiding device. The coating device may include a coating element assembly group that is, movably supported relative to the construction plane by the guiding device, and at least one coating element configured to form construction material layers in the construction plane. The shielding device may shield the second working plane area from intrusion of construction material or impurities from the first working plane area. 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.

The present invention provides a swarm manufacturing platform, based on a swarm 3D printing and assembly (SPA) platform as a model for future smart factories, consisting of thousands of IoT-based mobile robots performing different manufacturing operations with different end effectors (e.g., material deposition, energy deposition, pick and place, removal of materials, screw driving, etc.) and real-time monitoring. The swarm manufacturing platform transforms a 1-D factory into a 2-D factory with manufacturing robots that can move across the 2-D factory floor, work cooperatively with each other on the same production jobs, and re-configure in real-time (i.e., the manufacturing robots can be digitally controlled to move, re-group, calibrate, and work on a new job in real-time).

A 3D printing system includes a vat containing a liquid photopolymer resin and a rigid base on which an object is configured to be printed. A control arm connected to the rigid base is configured to move the rigid base relative to the vat. A first light source is configured to emit light to the vat to form the object on the rigid base. A second light source is configured to emit light on the object externally of the liquid photopolymer resin in the vat to cure the object.

The present disclosure is directed to a printer head for a three-dimensional printer, a three-dimensional printer, and a method for thermally managing printed filament temperature. The printer head including a thermal management system. The thermal management system includes a fluid passage defined by a fluid duct coupled to an air supply, a fluid nozzle coupled to the fluid duct, a first opening defined in the fluid nozzle, and a heating element included in the fluid duct. The printer head also includes an extrusion nozzle, including a first end and a second end, the first end of the extrusion nozzle is mounted to a support frame and the second end of the extrusion nozzle extends through the first opening defined in the fluid nozzle.
