3D prints are curling on edges for bigger prints.

This image is best showing a bigger piece where the edge is warping up. but the smaller pieces right beside it are staying in shape.

This is an attempt without any type of printing reinforcement. the brim did the same thing and the sled is a lot of wasted plastic....

it's the Ender 3 Pro. PLA 1.75. nozzle 200c bed 60c and I use a gluestick on the bed to help it stick.

I've always had better luck with nozzle temps around 220C with PLA. Are you sure you leveled the bed properly?

I got 4 prints lined up. I'll try 220c next one.

 

so I believe so, on the first layer it all sticks,but once it builds the bottom (I do .8mm walls/floor/cielings) it starts to barely show, once the walls start up is where it gets extreme (photos)

wait you can barely see the first layer because it's too thin? If that's the case, your nozzle is too close to the bed for the first layer.

curling/warping is a result of ill-adhesion or top layer is cooling more rapid than the lower layers.

 

lower your bed temp after initial layer.

usually first layer on my ender 3 is 215° and bed is 60°, then after first layer in complete it'll throttle back nozzle to 205° and bed to 40° no part cooling fan needed (ambient is enough).

 

use IPA to clean your bed surface and if you have some hairspray, a light misted coat can work.

from your pix, the first layer is a wreck.

under extruded and nozzle is too close to the build surface.

try .20 or .28 need and ender cura profile, i have several.

if you have the gcode or STL on that file, i can print it to see what you are experiencing on my ender 3.

depends on the part

a nice feature of prusa slicer is the smart fan

its PLA and unless you have 50° or larger overhangs, a cooling fan isn't necessary.

and from their pix, it is all pretty much a flat part.

Try a brim and see if that helps. The extra surface can help keep things stuck to the surface.

 

Also as suggested above give hairspray a try, I found it works better than glue stick for me. I use this Aquanet spray. You could also try a different type of glue stick and see if one is better than another.
