Abstract
A replaceable illumination cartridge system for three-dimensional (3D) printers. The illumination cartridge system includes a cradle assembly that is mounted to an underneath side of a resin tank in a 3D printing system. An illumination cartridge assembly is removably attached to and supported by the cradle for use in providing resin-curing light into the resin tank. Quick release attachment mechanisms may be used to secure the cartridge assembly to the cradle. The illumination cartridge assembly may be removed from the cradle for replacement and/or maintenance, and a new and/or refurbished cartridge may be subsequently reattached to the cradle for continued 3D printing. The illumination cartridge may include a liquid crystal display (LCD) screen or other suitable illumination device.
