Problem printing large flat tile

Hello everyone, another problem here…
Printing large flat tile, loosing adherence in the left side… tried petg (mistake) and pla+ but same result:

I tried one last time trying brim with 0gap. I thought it didn’t loose adherence, but the nozzle was hitting the left surface…

I’m printing with door open. What could cause this? Something with the bed? What could I check?

Thank you in advance for your help!

Oh the end near the aux fan lifted, what a surprise :wink:

why a print warps is that as the plastic cools, it shrinks.

  1. you can use a glue spray like 3dlac to help it stick to the baseplate

  2. you can try to even the temperature out, by enclosing the printer/shut the door (prevent draft), raising the bed temperature, lower the printing nozzle temperature, and reducing the chamber fan, and DISABLE THE AUX FAN

  3. you can print slower, and with thinner layers, to minimise how much and how fast you are putting down plastic

  4. you can try a low-warp filament

  5. you could print this thing in 4 pieces that clip together

Once you get the part to stick on large prints, your bed plate will actually lift of the bed. Been there done that. I’ve have great results printing large PLA prints using the cool plate and glue stick. Again, it will stick but the bed plate will possibly start lifting. I ended up using these printed in PC. They’re a pain to deal with but I was able to keep the bed plate flat and had no warping.

I also followed these steps as well.

Good luck, my experience has been large prints are likely to warp, this has been true with all of my 3D printers regardless of brands

To the people that always have to disable the fans…Try closing the door first.

Do this.

  1. Go to Nano Polymer Adhesive – Vision Miner

  2. Add a 50 or 120ml bottle to your cart

  3. Hit order

  4. Go over to Amazon and order https://a.co/d/dwHzQRn

  5. Heat the build plate up. I do 50c then put some on the plate use the foam brush you spread it out it will flash off fast.

  6. Enjoy It’s unmatched bed adhesion and ease of removal when the buid plate is cold.

For stuff other then the higher temp fillaments example Nylon, PC, PPS etc you can get a lot of prints before you need to reapply.

Even if you don’t use it every print. This is your tactic nuke against weak bed adhesion and way too much bed adhesion with stuff like TPU. This stuff is by fast the best build plate prep you can get. Second place is not even remotely close this would be a Koenigsegg Jesko absolute. Second place is a 2008 base model Chevy Cruze. But seriously once you try this you will love it. And this phrase gets used for pretty much anything in 3D printing because people just overuse it for anything. With this literally was a game changer for 3D printing. Anyone who’s printed PEEK we’ll tell you that this stuff is basically a miracle on a bottle.

Thanks everyone for your advices, I’ll try them all, starting from closing the doors and keep the fan off.
I printed all these gray squares, almost without problems

Same filament (sunlu pla+)

But… I was always using the door closed (and no strong hair spray, which I used in the last prints)

Could be that the big holes are helping?

Thank you again!

I can confirm, printing with door closed and AUX FAN off, the result was perfect!
Thank you again for all your support!

Glad you got it. I never print with the door open. Even in a warm room. Causes temperature swings and doesnt stop drafts. I originally couldnt leave the door open due to heat creep, but fixed that by cutting out the perforated section of the hot end cover out on both sides. I also did dual aux fans for printing pla and I run them both every time. A large brim with 0 gap is needed sometimes.

Also, I never use glue anymore either. It was a bandaid to cover other issues.
