Maintaining the Build Plate

Inspecting and Cleaning


The build plate is an integral part of the print process, but can cause issues if not maintained properly. Before every print, inspect the build platform for any cured resin. Any leftover cured resin can be removed with the scraper from the finish kit.

After part removal, rinse the build plate with Isopropyl Alcohol and wipe down with a paper towel to ensure that all material residue is removed.

Note: It is preferable to use 90% Isopropyl Alcohol to clean the surface, but lower concentrations of IPA will work as well. Lower concentration solvents will be slightly less effective, so they may require some extra rinse time.

Scratches and Gouges

When removing prints from the build plate, be careful not to scratch or gouge the build plate as the resulting raised ridges can cause punctures in the membrane.


Inspect the build plate after cleaning to ensure that there are no scratches or gouges with sharp ridges. If a suspected gouge is found, carefully use fingertips to detect if there are raised ridges. Be sure to wear nitrile gloves when handling the build plate to protect from material residue and abrasions.

If you find leakage on the LCD (as shown above), this indicates that the membrane may have been punctured. Inspect the surface of the build plate to see if there are any gouges that have sharp ridges before using the build plate with a new membrane.


Sanding the Build Plate

Due to mold release agents in KeyModel Ultra, the build plate surface may need to be roughened with 220 grit sandpaper. The plate should be sanded directionally up and down and side to side. The build plate can also be sanded in case a raised gouge is found.

After sanding, rinse and wipe down the build plate after sanding to ensure that there is not any leftover metal dust on the surface before use. Once the build plate is cleaned, use fingertips to physically confirm that the build plate has an even surface before use.
