We always recommend sanding the build plate (Textured & non-textured) to open the pores, even for brand-new build heads, to help remove cutting oils and contaminants and prepare the metal for the 3M bond.

We worked with 3M to have the best glue that would resist the harsh chemicals found in 3D Print Resins and Isopropyl Alcohol, but it does not do well on any metal with contaminants.

On top of it all, many printers are famous for not having a flat bottom, which will cause issues later.


When installing the new Magnetic Base please follow along with this video.


  1. Be sure to remove the old Magnetic Base and adhesive
  2. Check that your build plate is flat by laying a steel ruler on the edge across it in all directions and see if there is any light passing between it.
  3. Let the whole head sit for at least 30 minutes in an alcohol bath to remove residue from the entire build head and hard-to-reach places.
  4. Clean every surface of the build head well with pure isopropyl alcohol and a paper towel to remove all residue and dry well.
  5. Use 220-grit sandpaper on the bottom of your build plate to rough up the surface and open the pores and ensure there is no residue left
  6. Re-clean with alcohol and a fresh paper towel, repeat the process with a new paper towel until the towel comes away clean
  7. Let dry completely
  8. Then mount the Magnetic Base and leave it to cure for 72 hours.
