  • Page 109 Checking Printed Output Platform Locking Screws Removal If not removing the resin remnant sufficiently, the table, work area or machine exterior may become contaminated by the overflowing resin from the platform when carrying the platform. As shown in the picture below, please place the platform over a resin tank that resins accumulated on the platform drop to the resin tank.
  • Page 110 Checking Printed Output Important - As moving the platform away from the machine, be careful not to let the resin splash or spill onto any part of the resin tank. Insert blade of metal scrapper between printed output and platform and detach it by pushing scrapper slowly and carefully.

  • Page 111: Finishing The Printed Output

    Checking Printed Output - After removing the platform from the unit, be sure to close the orange cover. If the resin contained in the resin tank is exposed to external light for a long time, the resin may harden and cause the printing failure.
  • Page 112 Checking Printed Output Remove remaining resin using a brush or toothbrush. Use a sprayer to wipe out the fine gaps or holes in the output with IPA. Drying and post-curing Important - The curing time may vary depending on the printed output’s size and shape. - For quick curing, fill a transparent container with water, and put the printed output in it.

    Maintenance Machine Cleaning Caution - Turn off the power for the machine cleaning. If resin or cleaning tools go into the machine while the power is on, it may cause a machine malfunction. Printer Interior Cleaning During machine use, the resin may fall inside the machine. If the resin goes into sensitive parts such as any optical parts, it may cause a malfunction or printing failure.

    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 120: Resin Tank

    Maintenance If contaminants exist on a part where the platform is installed, platform leveling may fail, resulting in failed printing. Make sure that there are no contaminants remaining between the main body and the platform, and clean it using IPA and a paper towel if there is any. Assembly Surface Assembly Surface (Platform)
  • Page 121 Maintenance Checking the inside of the resin tank To check the inside of the resin tank, inspect it by scraping its bottom using the supplied rubber scraper. Look at the release film by carefully scraping resin from one side to the other of the resin tank. Rubber Scraper Important - Do not scrape the bottom of the resin tank too hard.

  • Page 122: Cleaning The Resin Tank

    Maintenance Cleaning the Resin Tank Caution - Wear nitrile gloves before cleaning. Cleaning the release film Use your fingers, a rubber scraper, or a gap gage mylar to remove residues of prints sticking to the release film and cured resin or particles floating in resin. Important - Do not scrape the bottom of resin tank hard.
  • Page 123 Maintenance Filtering remaining resin If the residues of prints or contaminants cannot be perfectly removed with your fingers or a rubber scraper, filter the resin through the cleaning filter to remove them. Pour the resin into a bottle with the cleaning filter to remove them. If resin does not flow down from the resin tank, lean the tank onto several layers of waste paper or paper towel, and use a rubber scraper to scrape down resin.

  • Page 124: Lcd Protective Glass

    Maintenance LCD Protective Glass The LCD protective glass is made of transparent glass to pass through LED beam with maximum efficiency. In addition, it prevents external dust or resin from penetrating inside the machine. For the best printing performance, it is very important that the LCD protective glass, through which the LED beam passes, is not scratched or contaminated.
  • Page 125 Maintenance Cleaning the protective glass ① The LCD protective glass needs to be cleaned only with IPA or a dedicated cleaner for glass and a clean microfiber cloth. Non-microfiber cloth or paper towel can scratch the LCD protective glass. ② Completely remove alcohol or glass cleaner with a dry microfiber cloth. ③ In a completely dry state, apply the glass coating agent evenly and let it dry for 10 minutes.

  • Page 126: 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 LED 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.

    Maintenance Reference - Pull the center part of the cover to easily close it. If you pull the left or right part, force is dispersed, which needs more force than the center. Cleaning the Orange Cover The orange cover needs to be cleaned only with a clean microfiber cloth and a dedicated cleaner for acryl material, for example, NOVUS No.
