How big is this print?

I verifide they didnt mean PLA. let em bang their hard heads on the wall I say lol

2) What are your heat settings?
3) Have you modified the print speeds?
4) Have you added a fan to cool the print?
5) Have you installed a slop nut or well nut to prevent Z backlash? I had this problem constantly when first printing until I installed something. And it always happened on one side as well now that I think of it.

@n2ri- A fan is pretty much required for PLA. You will rarely have good PLA results if you have an enclosure without a cooling fan. With ABS, since it cools too fast, will require a chamber to keep the heat in. A fan for ABS is a wonderful tool is you are:
1) Printing something very small
2) Bridging gaps
3) Have harsh overhangs

You are correct that ABS needs to be heated until the end of the job. In extreme occasions while printing with ABS slurry, I needed to turn off the bed heat because the temp under the slurry began to bubble, causing warping not on the first layers, but on the current tool paths.

You are having delamination. This is typically caused from lower heat than need:
*No enclosure
*Openings in the enclosure
*Lower heat settings than required

I have even seen bad filament do this (dirt/dust/moisture)
Any time this happens to me, which is rare, I change the layer height and it eliminates the problem.


thanks for this post. got in a big debate over this with the devinci guys last week they all claim you need a parts fan to cool the layers as they extrude to prevent this. I said ABS has to have heated bed til finished printing so how does fast cooling upper layers keep this from happening. they have inclosures but still issues on long prints.

geez them guys where hard headed. thought I was going nuts lol. finally saw I was in the devinci forum so just left it.

You could have good adhesion on the first layer, but as it builds higher and the infill cools and tugs, it is possible it is giving this result.

+1, also try a lower infill

Anyone know what is causing this?
