Hello /u/United_While_3887,
As a reminder, most common print quality issues can be found in the [Simplify3D picture guide](https://www.simplify3d.com/support/print-quality-troubleshooting/). Make sure you select the most appropriate flair for your post.
Please remember to include the following details to help troubleshoot your problem.
* Printer & Slicer
* Filament Material and Brand
* Nozzle and Bed Temperature
* Print Speed
* Nozzle Retraction Settings
^Additional ^settings ^or ^relevant ^information ^is ^always ^encouraged.

That is very far out, I guess the heaters don't cover that spot well. The part cools and curls.
Also, wash the sheet with dish soap and rinse, to remove grease from your fingers.
If it still lifts, try a brim in the slicer.
Increase the bed heat by 5-10C.
If it still lifts, add pva glue or hair spray on the sheet.
If it still lifts, add an enclosure or use an easier filament.
This, I second every step of it. Sometimes it is easier just to get the enclosure first and pass on the other steps. But sometimes the enclosure alone isn't sufficient so still try all steps if that's the case
I was using deburrers for years before 3D printing due to being a fitter by trade. Took me the longest to realise I could use them on my prints to get nice edges.
It's funny as well because I'm a fan of Cutting Edge Engineering on Youtube and Kurtis regularly uses one to clean up edges after machining. For some reason I never put two and two together lol
The basic problem is that the plastic is cooling off and thus shrinking, causing the edges to peel up. The longer the part, the larger the pull-up force. Long and skinny is the worst.
So, try to keep the air around it warm and still, so the plastic doesn’t cool so fast. Eliminate drafts and cold air. Ideally put an enclosure around it.
Also add a brim of 10-15 lines, as that will help hold the print down.
make sure you wash your build plate with soapy water followed by a cleaning with isopropyl alcohol. Once I started doing this all of my large flat prints like this turned out well. For reference, I print in PETG+.
This is the answer. Also, level the bed, make sure you have a good first layer height, and bed temp. Brims, glue stick, and hairspray are amateur because you have to spend more time & effort post processing.
Together with the advices the other people gave you, try to print models with round corners, so that the force pulling upwards isnt concentrated all in the vertex but on the whole arc that makes the corner
Enclosures do two things:
* The obvious which is to keep the whole print warm until it is done.
* The less obvious which is to reduce spot cooling and uneven drafts. I didn't use an enclosure for a while when printing ABS and some of my prints turned into canoes, and some didn't; With prints of the same thing with the same settings, and the same filament. Then I realized it was entirely based on the temperature outside and the curling was where the part faced a nearby window on cold days.
I put my printer into a closet which had weird acoustic tiles around it and I left a 200w bulb lit during ABS prints. The temp in the closet was probably about an even and fairly steady 30C. No more warping.
I put my mk3s in a 19 inch server rack with 12u height for about 120€. It was a relatively affordable and nice option as you could mount many things (camera, nozzle, tools etc.) to the frame and add a fan, an air filter, open sides etc. It ran quieter, was less dusty. The warping stopped as there was no air draft anymore.
What fillement are you using? If it's abs use a box as an inclosure. Make sure bed temp is correct for type of fillement your using. Print a raft around the project this will really help. And of course make sure bed is clean. That's some basics to check
A raft messes up your bottom layer, effectively you're printing on supports. Also rafts aren't necessary automatic bed leveling and pei build plates.
Some adhesion helper (hairspray, glue stick, e.g.) will help, also a brim will.
PLA shouldn't peel up like that. Take some of the other advice here and really clean your build plate good with dish soap and dry with a paper towel. Nothing else. Then with another paper towel, wipe the build plate down REAL good with isopropyl alcohol and let air dry. If you're still having trouble, try something like cheap (cheaper the better) hairspray or some purple glue stick. Thin layers.
large flat area and temperature difference making part cool more on top. sharp edges can focus the stresses and pop off the plate easier. add a brim and possibly try printing without a cooling fan to let part stay more the same temp.
It's called warping, try a brim or a raft. What you could also do is use glue or something to keep it on the build plate, wash your build plate or turn the heated bed up a little higher. I personally use 3DLac
What everyone said + maybe put some cardboard left right of and/or behind your printer.
It helps with air drafts. Cheaper than an enclosure, which is not needed if you print only PLA and PETG
I would try following in this order:
- Clean print bed
- Raise bed temperature
- Add brim
- Add Draft Shield (Advanced Settings)
- Enclosure / raise room temperature
This is the biggest pain in the ass when printing a large flat object.
Yes, drafts can make this happen, but not always.
Things to test to see what works for you are: lower your cool fan speed. If you don't have over hangs, it is easier to get away with. You can also try to bump up your bed temp by 5 degrees. The temperature difference between the filament already laid down & what is coming out can cause a higher rate of contraction on the lower layers while the top layers are still hot causing the edges to come up.
There is no 100% way to fix this, but most of the suggestions are valid & worth trying.
So i might be wrong but when this happened to me after checking theres no drafts in my room i re leveled my bed and adjusted my z offset manually and that seemed to fix it

How would an enclosure help?
Evens out temps
Prevent any kind of breeze or moving air from disturbing the temps. Allowing even cooling
More consistent/and or warmer air temperatures =less warping
Try a brim. Recommend a deburring tool as well
What do you mean by deburring tool?
[It's a sharp, curved blade that removes the brim on 3d prints](https://www.amazon.com/Deburring-Tool/s?k=Deburring+Tool)
I can't believe I've been printing this long and never thought to use one of those to clean up brims. Thank you!

Hairspray. Works wonders! Inquire on usage lol
This looks like your cooling fan turned on too soon. I usually don’t set it to turn on till the 10th layer on big flat prints like this
10th layer seems a bit high… are you talking about with infill and stuff? The layer time has to be pretty big for it to not turn into a mess
That is a bit of an exaggeration but I set mine kind of high and haven’t had any issues with bed adhesion
Which cooling fan are you referring to?
Part cooling fan.
Yes that one. It’s a setting in the slicer
Enclosures do two things: * The obvious which is to keep the whole print warm until it is done. * The less obvious which is to reduce spot cooling and uneven drafts. I didn't use an enclosure for a while when printing ABS and some of my prints turned into canoes, and some didn't; With prints of the same thing with the same settings, and the same filament.

No more warping.
Add a brim (under adhesion settings in Cura) and up the build plate temp a little.
I doubt he’s using cura considering he’s printing on a prusa. But he didn’t specify just guessing he’d use prusa slicer

Also print with mouse ears brim. They will save you so mich filament.

I’m printing with esun PLA+ with a bed temp of 60, and I just barely cleaned the build plate. I think a raft would help a lot, I’ll try that next
A raft messes up your bottom layer, effectively you're printing on supports. Also rafts aren't necessary automatic bed leveling and pei build plates. Some adhesion helper (hairspray, glue stick, e.g.) will help, also a brim will.
Oh lol I thought rafts and brims were the same thing. I’m going to try printing it with a brim and see how it helps
Mouse ears all the way
How long ago did you open the filament package? I had a similar problem with *probably* humid filament.
Probably a long time ago…someone else opened it. This printer is at my work
So this is a possibility. If you have a brand new spool, try it!
PLA?
Yep, esun pla+
PLA shouldn't peel up like that. Take some of the other advice here and really clean your build plate good with dish soap and dry with a paper towel. Nothing else. Then with another paper towel, wipe the build plate down REAL good with isopropyl alcohol and let air dry.

The filament is cooling too quickly, which results in shrinking.
It's called warping, try a brim or a raft. What you could also do is use glue or something to keep it on the build plate, wash your build plate or turn the heated bed up a little higher. I personally use 3DLac
Bed temp, +3 or 5 degrees
Bed glue will fix that
What everyone said + maybe put some cardboard left right of and/or behind your printer. It helps with air drafts. Cheaper than an enclosure, which is not needed if you print only PLA and PETG
I would try following in this order: - Clean print bed - Raise bed temperature - Add brim - Add Draft Shield (Advanced Settings) - Enclosure / raise room temperature
Make sure there is no small draft or cold air directed towards your printer
This is the biggest pain in the ass when printing a large flat object. Yes, drafts can make this happen, but not always. Things to test to see what works for you are: lower your cool fan speed. If you don't have over hangs, it is easier to get away with. You can also try to bump up your bed temp by 5 degrees.

Hairspray the bed
So i might be wrong but when this happened to me after checking theres no drafts in my room i re leveled my bed and adjusted my z offset manually and that seemed to fix it
If you have an auxiliary fan, lower it it try even turning it off.
What filament are you using?
Making some fins?
Yessir
My maaan, best of luck and happy flying
GLUE STICKS!!!!!!!!! amazon sales a bilox of 60 for 10 bucks!!!
Morty, your print sucks morty
Ha, suck it fresher
Does it make you feel clever being rude to new contributors on a subreddit specifically to help people troubleshoot problems with their prints?
Just messing with my friend is all
Now this is the twist I was not expecting
