The 3D Systems Installer should have performed the initial fill and priming of the resin tray in your Printers. After this initial fill, the machine will automatically pump more material into the resin tray as needed before a print job. The machine will alert you when a cartridge is near empty, and then further when it is completely empty. Please follow the instructions in the section Load Material Cartridges to remove the old cartridge and install a new one.
There may be some cases, such as after installing a new resin tray, when you must fill the resin tray from empty. The following sections describe how to do this.
