Does anyone have tips or tricks that they do to prevent curling?
Which material, ABS?
Yes.
I use a heated bed with pei on it, bit if I need a little bit of extra help, I do a large brim so the brim curls and not my part as much.
PEI is great for abs but you must have a heated bed. Brim definitely helps but I’ve printed some wide parts in abs on PEI with no brim and really no warping
Use a powder based 3D Printer
For me the trick ended up being finding the right painters tape and using a heated bed for ABS.
I live in Canada and only really have access to Home Hardware, they carrier a few different colors of painters tape and they have a blue one (not sure of the brand) that ended up working perfectly! At first glance I didn’t think it would work, because it has a lot smoother surface than the green tape they carry, but somehow PLA and ABS stick to this blue tape incredibly well. And the blue tape really sticks to my aluminum bed.
My bed doesn’t want to go above 80deg which still caused a bit of curling on this blue tape, but I discovered if I applied a coat of glue from a Glue Stick on top of this tape at 80deg bed temp, I was able to print ABS without warping or curling.
Infill percentage affects the amount of lifting as well. If you don’t need the strength in the part, try printing with less infill. In my experience, large, flat parts that are printed solid will lift every time; while the same part printed with 10 or 15 percent fill will print flawlessly. I’ve also had success by increasing the wall thickness by a layer or two to give strength and use the low infill to prevent warping.
is changing the material an option?
@Marcus_Wolschon holds a good point. If it doesn’t have to be abs then print it in PLA.
