Build Surface Maintenance

Apply New PEI Film

You will need...

  • New PEI film
  • Water
  • Mild dish soap
  • Paint scraper
  • Razor, box cutters, or xacto blade

With a very dilute mixture of dish soap and water (1:200 or less), apply evenly across the build plate surface to create a liquid film.


The dish soap acts as a surfactant to allow the water to properly wet the build plate surface.

Take your new PEI film, remove the adhesive protective sheet, and place on the build plate. Using the paint scraper, squeeze the liquid out from underneath with repeated passes until all liquid is removed. Trim excess film using a sharp blade.

Cure the adhesive by placing the build plate with a heavy flat object placed on top inside the printer and turning both the chamber and bed to 100°C for 12 hours.
