Solution for adhesion problems with ceramic resin

I have been using ceramic resin with good success for years, but on a recent project had a big problem with parts not adhering to the build platform, and completely falling off during the print. I prepared the platforms as instructed with sandpaper, carefully cleaning, making sure the platform was not cold or contaminated with anything before the print, etc, but still could not complete a 3 hour print without the part detaching.

Here’s what completely solved the problem for me: I prepared the build platform with sandpaper, and cleaned with alcohol, then dipped a small piece of paper towel in plain clear resin (eg from a nearby tank), and used it to spread a very thin layer of clear resin on the platform. I used enough to make a coat of resin thin enough that would stay in place when held vertically – like painting the wall of a house. Then, I put the whole platform in the curing machine for 5-10 minutes at 40*C. This mostly cures the resin, but it will still be tacky, and also ensures the platform will be warm. No more adhesion problems! After the print, I clean the platform by scraping it with a single-bevel end-cutting Xacto blade (looks a chisel), then sandpaper. If I know that I’m only going to print with the center of the platform, then I only do this treatment around the center area. Good luck!


Was this the standard platform or the all-welded-stainless one?
On the Form1+ our build platforms all eventually leaked so when we bought a Form3 I upgraded to the all-welded platform.

Not that it’s likely I’ll be fiddling with the ceramic resin, but you never know, we might need something that will survive in a plasma cleaner, or in/near a synchrotron X-ray beam.

Standard platform. Actually, I didn’t know an all-stainless version existed, and just now checked it out. Wow $250, but yeah, it seems like a useful upgrade. I had problems with the end caps coming loose on a standard platform a couple years ago. No issues since then. The ceramic resin is especially aggressive, and seems to degrade the black plastic more quickly than other resins. You should definitely post about your parts being used in synchrotron beams :slight_smile:

So far just bits and pieces (some used in LN2) on a novel CryoEM plunge freezer.
The Rigid 10K seems to be LN2 friendly.
