Adhesion first layer issues with PEI Textured Plate

Hi all,

I’m starting to get adhesion issues with the Bambu Textured Plate in specific areas. Never had any problems with other prints until today. I’m using PLA basic currently and I always slow down the first layer speed and increased the temperature of the nozzle and build plate. I did notice that this layer is labeled ‘Bridge’ but unsure what the problem could be. Anyone encounter similar issues?

Thanks all

Have you washed your build plate with dish soap? Finger oils can reduce adhesion where you touch the build plate with your fingers. Since those two locations are near the edge of the plate, you may have grabbed the edges and flexed it to remove a previous print, depositing oils onto the plate.

Hi RandomKhaos,

Yes! I washed after every fail. It seems like this area in particular is having trouble sticking to the plate. I slowed the the bridge speed on my 3rd attempt and it happened again but just on one side. So far, I haven’t had any problems with the Textured plate until today… I’ll try rotating the object and see if that makes a difference.

It means that the model isn’t touching the build plate in that area. It’s possible your model isn’t flat against build plate or that you need to lower it into the build plate so the entire first layer touches.

Does Bambu Studio give you any warnings when you slice the model?

Hey Jon,

Yes I understand what you mean. The model isn’t 100% completely flat but it’s 99%…the problem is this model is just 1 section of a larger piece so I don’t know if lowering it could mess up the reassembly? Would lowering the model 1-2 layers make a large difference when I reassemble later? It definitely takes out the bridge and turns it into a bottom layer!

It’s tough to know if removing a layer or two will cause issues with assembly as you haven’t provided any info about the model or what it mates to.

My gut feeling on a model this big, .4mm in height won’t make any difference.

PS - Welcome to the forum!

Thanks Jon! I’ve moved the model .25 mm lower and got rid of the bridge. Hope it works. Will update shortly…

This is a bit off topic, but I have both the gold Bambu PEI plate as well as a bunch of the Juupine (Ali) gold PEI plates, and for some reason the adhesion is terrible on the Bambu plates and great on the Juupine plates. All plates been washed, wiped with IPA etc. Adhesion is so bad on the Bambu with PLA and ASA I have to use nano polymer adhesive with challenging projects, whereas the aftermarket plates just work. As a bonus they are only $15 each, no QR code but I have that disabled anyways.

Odd. My PEI texture plate works like magic without any issues but the plate that comes with the printer sucked. Not sure why they don’t just include a textured plate instead of the basic plate/ glue option.

The issue for my model was that it wasn’t completely flat so the printer was printing a ‘bridge’ layer directly onto the plate instead of on a ‘first bottom layer’ which caused adhesion issues.

I’m having the same problem on the gold colored Textured PEI Plate… The plate was working great on PLA, PETG, and ABS but all of a sudden it started having adhesion problems with PLA. I’ve tried cleaning it with 99% IPA, dish soap and hot water and acetone but for some reason PLA just won’t stick any more.
Not sure if it’s simply coincidence, but to me it seemed like the adhesion problems started after I printed a rather large (surface area on place) TPU project.

I haven’t used TPU to know if any of this may help but some scuff the surface of textured PEI with a scrub pad. Others use liquid glue spread thinly across the plate.

If it still won’t stick, build plates are considered consumables. It could be you have a TPU plate and need a new one for PLA?

I have noticed that using a smoth build plate with a bit higher bed temp works well for me, for either TPU and or PLA so if your noticing issues try a smooth plate and see if that works better

in my case the plate is only about a month old and it’s not a production machine, just some general interest stuff. Perhaps a total of around 20 - 30 hours of printing on that plate so far. Agree with you on the consumables aspect, but don’t think I should need to replace the plate every 30 hours of printing.
As an update, I’m using the Smooth PEI Plate/High temp plate now and the PLA is sticking, so far. Perhaps I’ll try scuffing up the textured plate to see if that helps.
Previously I was using a Prusa and one standard plate for “years” and never had to replace it… Just a good cleaning with soap and water every once in a while and a quick wipe with IPA before every print.
Anyway, not complaining, and am looking forward to trying some 3rd party plates for my X1C.
Thanks for your comment and help.
