Abstract: A method and system for photopolymerization 3D printing is provided. The system includes a processing device, a micro light emitting diode (microLED) array including one or more individually addressable microLED emitters, and a printing component. The processing device is configured to determine one or more printing layers of an object. The microLED array is configured to generate light for each of the one or more printing layers. The printing component is configured to print the one or more printing layers. To generate the light for each of the one or more printing layers, the processing device is further configured to dynamically determine one or more microLED regions in the microLED array, determine one or more region printing parameters for each of the one or more microLED regions; and determine one or more control signals for the one or more individually addressable microLED emitters included in each of the one or more microLED regions based on the one or more region printing parameters.

Abstract: In the embodiments of the present disclosure, additive manufacturing devices and methods are provided. The additive manufacturing device includes a light source, a building device, and a light scattering member. The light source is configured to provide light to cure photocurable resins. The building device includes a resin tank configured to store the photocurable resins. The building device has a building surface on which the photocurable resins are cured. The light scattering member is arranged between the light source and the building surface.

The light scattering member is arranged between the light source and the building surface. The light scattering member is configured to alter a light propagation direction of the light from the light source to cause an inner-pixel light intensity change on the building surface.

Abstract: A multiplexer is constructed, which has a stable volume over its thermal operating range. A composite material is used that utilizes a fabric having fibers of opposing coefficients of thermal expansion. Such fibers are assembled at an angle to each other so that resulting expansion and contractions counter act and cancel. One of the fibers is selected for its high thermal conductivity and extends over the length of the multiplexer to form a heat dissipating path.
