TECHNIQUES FOR ADDITIVE FABRICATION UTILIZING LCD AND/OR LED LIGHT SOURCES AND RELATED SYSTEMS AND METHODS

An improved additive fabrication device includes a build platform, a vessel designed to hold a liquid photopolymer, and an optical system featuring a micro-LED panel. The micro-LED panel, comprising multiple pixels, projects actinic energy toward the photopolymer in the vessel. The panel selectively...

Zusammenfassung:	An improved additive fabrication device includes a build platform, a vessel designed to hold a liquid photopolymer, and an optical system featuring a micro-LED panel. The micro-LED panel, comprising multiple pixels, projects actinic energy toward the photopolymer in the vessel. The panel selectively activates pixels according to a mask pattern, enabling precise control over the fabrication process. This innovative device offers a streamlined approach to additive manufacturing, utilizing advanced optical technology for efficient and accurate production of complex structures.
