Which has better PLA adhesion: Textured or Smooth PEI Plate?

[user_3805429206]

I currently print on a textured PEI plate and occasionally the prints become un-stuck, even with a brim. I am wondering if the smooth PEI plate offers superior adhesion? I use a H2D printer and mostly use PLA

I’ve personally found that the smooth plate has better adhesion. There is also the added bonus that you can normally physically see when the plate has contaminants such as finger oils on it as it turns shiny. The downside is that the surface of the print against the bed isn’t as nice as the textured plate and it doesn’t hide the slight lines between the extrusions as well.

Its hit and miss at times with the Textured plate with PLA and PETG on all my machines. The Smooth BL plate with the stick glue works 100% of the time with both. I ordered a second smooth for the second H2D, and plan to convert it to a C when the kit is available and find out that the plate will be different. Oh well, never hurts to have a spare then.

I only use CFX plates, which are similar to smooth PEI. Just keep in mind that some models can create suction to the plate and be ridiculously hard to remove.

Smooth PEI has better adhesion, textured was designed for better release of model for PETG and TPU plus more durability. If you want more info (and the rest of this can of worms) you can check this old thread:

X1c vs p1s

Again smooth PEI was made for better adhesion, and textured for better releasing. Yes there is a bit more surface area but also the plastic does not seep all the way into the texture and there is some air under the print on a textured plate, hence the easier to release. PETG and TPU stick too well to smooth and can rip the surface, thats why textured was developed for durability and easier releasing. Think of a suction cup on a windshield vs a rough surface. This info is direct from multiple ma…

as someone who had little experience with anything but the default smooth plate that came with my old prusa, it is funny how basically this entire situation is reversed from what my intuition told me. The new textured plate has higher surface and is ‘newer’ so they must have better adhesion because that is desired! Oh and glue sticks obviously GLUE things so this is to get these prints to realy really really stick! Wrong on both accounts

I’ve had great luck with both, however, I bump the bed temp up to 60 from the default 55. There were many reports of inconsistent bed heating temps so this seems to have worked for me. Your mileage may vary.

The new bambu textured PEI plates have a coating on them that they added around the launch of the H2D. The grips is much better than older plates, but it does wear out with time. A Kdeavi (or Frostbite) and Glacier (for Nylons) plates are still the best solutions for best long term adhesion.
