Curling Edges (ABS)

mreagen · 2016-07-23T09:13:53.000Z

I am using a Flashforge Creator Pro with Simplify 3D software…

When I print a rectangular object, the edges begin to curl upwards. I am using default settings in Simplify 3D. What settings should I adjust to cure this problem? It seems to be more evident with the left extruder (the one closest to the fan that cools the filament) so im thinking its a cooling issue.

Bed leveling is always the go to for this. However if you are satisfied your bed level is true, you could try hair spray for bed adhesion (works for me), or apply a raft

I can’t give you a definitive answer, but I had curling of PLA filament on rhs (without fan). When I put filament on LHS (with fan), the curling stopped.

perhaps put abs on the rhs and try?

Make sure your build plate is heated to at least 110C. Go with 20% or less infill and use Kapton tape. Hairspray is good and the cheap way out, but I’ve found that Kapton works better and consistent

I’m going to take a stab at what you’re printing with, and guess PLA. (didnt see description haha, ABS it is, see below, bed adhesion is the likely candidate) Theres a couple of things. Print speed could be too quick, check out “outline underspeed” setting. I can’t remember what the default is (I think it’s 50, but you could try 20%. You should experiment with the early layers and cooling speed. Try a lower fan speed for the first 2 layers (but not much more than that, as you’ll risk re-melting as you apply more layers. If you haven’t experimented with simplify3d, you can delete the default cooling option, set it to 50% for layer 1, then 100% for layers 3 onwards. To do some testing you could try some quick 3 or 4 layer squares, to see how much it lifts up before trying full cube again. The next issue would be the platform you’re using. How hot? Try lowering the temp. Looking at your photo I’m guessing you’ve got kapton tape? Are you using hair spray? (probably the most common / best adhesive for PLA). Advice here is feared towards PLA. ABS is entirely different! In which case, I’d recommend abs juice, and a lower outline speed. Sorry for all the words, and I hope I’ve helped out! Cheers, Sam Extruded Designs

The build plate is heated to 110, and my infill is set to 100% because the part requires it. Im printing on the square blue sheet that came with my printer.

The print speed is actually quite slow, I set the quality to “high” so I dont think thats the culprit. Fan speed is 0% as recommended by a simplify 3D tech. I am printing with ABS.

the bed is leveled perfectly. im thinking its the adhesion. I ordered a glass bed kit but it still has not come.

Definitely try dipping an old part in acetone for a second or 2,then wiping it across the area you’re printing. Try and use the same colour old part, as the colour that you’re printing. I also found the blue build take sheets you get from flashforge did this to me after a reasonable amount of use. Try an area you haven’t used the build plate much, or alternatively, replace the blue sheet with a fresh one. Abs sticks very well to a fresh sheet of that stuff.

If the infill is 100% you need to reduce the cooling, therfore I would heat the build plate up even higher. At this point its trial and error until you get the right temp. Geometry and orientation are a big part of how your part shrinks. Using default settings almost never work. Good luck.

Try printing with a raft. That helped reduce warping for me on certain sizes and shapes

Hi Mr Egan, 234 for extruder and 110 for the first few layers on the heat bed and then drop to 90. For ABS - on a box shaped item, no fan at all. I get flat prints but I had to go to extremes to get it with my Dreamer. It looks like you have a few other issues as well. You can join me on 3D Printing Club | Facebook , plenty of help there with around 23K memebers. Have a good one. Bob.

Looks like over extrusion to me.

Have you calibrated your extrusion multiplier? Not on my computer so can’t post the model I use. But it is a 2 wall cube and then measure the thickness.

this is the method I use

I’ve had awesome results with:
bed 90°, kapton tape with acetone slurry and no cooling. ABS is a little bit tricky. Different colors and different spools are having different setups. Usually I’m using 235°-240° as printing temp. I hope this helps
