For the best print quality, it is very important to keep optical parts such as transparent window and flexible film clean and undamaged. If window and film is scratched, damaged, or contaminated, laser beam will be scattered, reflected or blocked. These defects may cause degradation of print quality or print failure.

For the best performance and life, ensure that resin tank is maintained as directed.

1.4.1 Resin Tank Life

Resin tank’s life can vary depending on shape and size of prints, printing location, layer thickness and resin type. If resin tank is well maintained, it can be used generally until at least 100 print jobs or 1,000 hours

Film needs to be replaced if a hole, scratch, tear, stretch or any types of serious damage occurs. In addition, replace transparent window if it gets scratched or dirty with contaminants, which cannot be removed.

1.4.1 Checking Resin Tank

Wear nitril gloves before starting cleaning.

Thoroughly check the resin tank in case that print quality is not good, print failure occurs, and resin tank is changed. Before starting new print job, clean the resin tank and check if problems exist.
