Printer Interior Cleaning During machine use, the resin may fall inside the machine. If the resin goes into sensitive parts such as a conveyor belt or any optical parts, it may cause a malfunction or printing failure.

  • Page 135: Platform

    Maintenance Platform If debris of print or contaminants exists on the surface of the platform or in its holes, platform leveling may not be performed perfectly. They may cause a degradation in the print quality or print failure. For the best printing performance, clean the platform regularly and after each printing job. Caution - Wear nitrile gloves before cleaning.
  • Page 136 Maintenance Clean remaining resin using a paper towel and IPA. Finally, clean all residual IPA using a dry paper towel. Caution - Do not place the IPA close to fire because it is flammable. If contaminants exist on a part where the platform is installed, platform leveling may fail, resulting in failed printing.

  • Page 137: Resin Tank

    Maintenance Resin Tank The resin tank consists of aluminum die-casted walls, a transparent window, a release film, and silicon rubber gaskets. For the best print quality, it is very important to keep optical parts, such as the transparent window and the release film, clean and undamaged. If the window and film are scratched, damaged, or contaminated, the laser beam will be scattered, reflected, or blocked.

Sealing Cap Storing the Resin Cartridge Store resin cartridges in a dark and well-ventilated place.
  • Page 144 Maintenance Caution - Be careful not to put IPA on the resin tank or other parts of the cartridge by mistake. Ensure that IPA is completely drawn and removed before restarting to use. - Ensure that the cartridge is not upset to prevent leakage of resin while cleaning. It is recommended to install the sealing cap first.

  • Page 145: Orange Cover

    Maintenance Orange Cover The orange cover is made of translucent orange acryl material to allow users to check the situation inside the device. Orange acryl is a specially selected material to safely shield the laser beam. To prevent users from accidentally using the machine with the cover open, double safety systems are installed. It is designed to stop temporarily for the safety of a user because if the cover is opened during printing, it may cause reduced quality or failed printing.
