Abstract
A three-dimensional (3D) printer includes a build platform, a resin tank configured to hold resin, a micro-light emitting diode (LED) array including micro-LEDs situated to provide ultraviolet (UV) or blue light to the resin in the resin tank, and a control circuit configured to control which LEDs of the micro-LED array are active and pattern the light produced by the micro-LED array for selectively curing the resin in the resin tank.
Claims19
A three-dimensional (3D) printer comprising:
- a build platform;
- a resin tank configured to hold resin;
- a micro-light emitting diode (LED) array including micro-LEDs situated to provide ultraviolet (UV) or blue light to the resin in the resin tank;
- and
- a control circuit configured to control which LEDs of the micro-LED array are active and pattern the light produced by the micro-LED array for selectively curing the resin in the resin tank.
A method for three-dimensional (3D) printing, the method comprising:
- controlling, by a control circuit configured to control ultraviolet (UV) or blue light emitted by light emitting diodes (LEDs) of a micro-LED array, a pattern of light emitted by the micro-LED array;
- and
- selectively curing, by the light from the micro-LED array being incident on a resin in a resin tank situated to receive the light, the resin.
A control circuit comprising:
- circuitry configured to:
- control a pattern of ultraviolet (UV) or blue light emitted by light emitting diodes (LEDs) of a micro-LED array;
- and
- move, by one or more motors coupled to a display platform on which the micro-LED array is situated or a build platform to which a cured resin adheres, the display platform or the build platform.
