Have you ever looked at your scratched up mess of a build platform and thought, “Maybe I should just buy another?”
I found a simple way to restore the platforms to like new status quickly and easily. It takes about 5 minutes and you will need a sanding block, some sand paper, and access to a sand blaster.
Here is my nasty scratched up build platform:
Wet sand it with 250 grit and 600 grit sand paper using some dish washing detergent as a lubricant. Rinse and dry it off completely. It doesn’t need to be perfectly scratch free. I only sanded this for maybe 1-2 minutes.
Sand blast the surface. In my case I have 220 grit loaded so the surface is a little smoother than stock. When done, wash the platform in soap and water again, then dry. 50 or 100 grit would make it look and feel completely stock.
Here is a comparison between the refurbished and a brand new unit. The whole process took me maybe 5 mintues start to finish.
