Gaps In My Box Walls

[akruse12]

I'm new to #D Printing so I need to some help. I have a FlashForge Creator Pro. I printed out a large box but as the walls were being printed they separated about every two inches at the corners. Is it because of a heat or cooling problem. What can I do to fix this. I'm using Simplify3 software. I have included some pictures. Thank you, Allen

I can see some warping on the lid of your box and I suspect that is the main cause. Do you have an enclosure for your printer to keep everything nice and warm?

Is this ABS or PLA? Do you have a heated bed? What settings are you using?

Looks like the bottom corners warped too - I agree with above, would be helpful to know what settings you used to print this.

that would be typical for any med to large boxy print done in abs. too much internal stress. there isnt a whole lot your going to do about it. its abs and the nature of the beast. print the same file in petg and you wont have those issues.
