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. Alternatively a wide wood chisel, or razor scraper tool can be used or may be needed for very thin layers of cured material. 

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.

Scratches and Gouges

When removing prints from the build plate, avoid deep scratches or gouging of the build plate. Small gouges are ok, but you must knock or sand down any raised ridges can cause punctures in the membrane. If you have dropped the build plate check for dents on the corners or edges, these must also be removed by sanding, shaving, or deburring.


Inspect the build plate after cleaning to ensure that there are no scratches or gouges with raised ridges. Run a flat steel tool over the full surface to verify no raised edge catches it.

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.
