Bed adhesives. I'm on a quest for the best

Bambu Lab P1 Series General Discussions

There’s a lot of random threads on this topic but nothing straight from the membership’s mouth. So here we go.

  1. Do you use adhesives?
  2. If Yes, what type liquid, solid or spray(mention brand please)?
  3. What type of bed do you use adhesive with?
  4. What type of filaments do you find yourself requiring adhesive and what combination of plate and adhesives?

Here’s my use-case where I’ve not found a 100% satisfying solution. Thoughts or suggestions would be welcomed.

  • I use quite a bit of PETG which sticks to EVERYTHING whether you want it or not.

  • I have a number of projects where I am seeking glass-like finish on both sides so a textured plate does not meet the needs for those projects.

  • PETG harms PEI plates unless I use adhesive and even then I’ve ruined too many plates.

  • I use the Bambu High Temp plate which produced a smooth surface but not glass-like.

  • The only combo I found that provides both easy release and works but is not glass-like perfect, is the high temp plate using hair spray in multiple coats. The hair spray has to be washed off and the plate needs to be re-treated if I don’t want the marks from the previous prints to show. That can take a few minutes for each coat of spray to dry if I want to get that mirror like sheen.

  • I did purchase a specular smooth PEA plate that advertised mirror-like finishes and it was Meh!!! My Smooth PEI plate performed as well.

I found that the Bambu liquid adhesive although effective, does not apply evenly. If I want a glass-like finish, I can’t use it as the streaks will show through. Plus, it’s way overpriced in my view.

I also find that the prices charged for specialty adhesives are whacko crazy. I mean some of this sh*t on an ML per ML basis is 5X the price of a mediocre single malt. No justice there in my mind. :confused:

I’m experimenting this week with my own formulas and applicators but I wanted to hear if anyone had any tricks up their sleeve.

This is what I do.
Works great for me.

I’ve got P1S and I’m mostly using the textured PEI plate which was in the box. To be honest, I have never used any additional adhesives for PETG or PLA. There was only one situation when I had an issue with adhesion, but the only thing I needed to do was to clean the plate with warm tap water and soap.

So in my case, I just make sure there is no oil from my hands within the print area and that’s all. That also applies for the PEO plate I purchased from Aliexpress

Thanks for sharing. That’s an interesting approach. I’ll give it a try.
