Repairing Damage to PRINTinZ Build Surface

Repairing small areas of damage to the PRINTinZ build surface, such as gouges or nicks in the surface, is an easy process and will extend the life of your PRINTinZ.  (If you wish instead to remove and replace the PRINTinZ build surface, instructions can be found here.)

Tools/Items Needed: 

  • J-B Weld "Clear Weld" (or similar two-part epoxy) 
  • Tongue depressor (or similar applicator) 
  • Paper Towels
  • 70% Isopropyl alcohol
  • Sandpaper: 100, 200, and 400-800 grit 


  1. Thoroughly mix together a volume of J-B Weld "ClearWeld" two-part epoxy (or similar epoxy).
  2. Using a tongue depressor or similar applicator, fill the damaged area(s) with the newly-mixed epoxy.
  3. Smooth over the surface of the damaged area(s), ensuring that the epoxy completely fills the hole(s). This step is to reduce the amount of sanding you will need to do in a later step to create a level print surface.
  4. Use a paper towel to wipe up any excess epoxy. 
  5. Allow the epoxy to completely set for the manufacturer's recommended time.
  6. Sand (wet or dry) the epoxy filling so that it is level with the surrounding PrintinZ surface. Work slowly, making sure not to remove too much epoxy. The suggested sanding steps are as follows:
    1. Start with 100 grit to remove the majority of excess material.
    2. Use 200 grit to get level with the surrounding print surface.
    3. Finish off with 400 or 800 grit for a smooth build surface. 
  7. Clean the surface with a paper towel and water.
  8. Clean the surface with a paper towel and 70% isopropyl alcohol.
