Tiles Breaking from Upper Part on Bambu Lab Carbon X1C

Bambu Lab X1 Series Troubleshooting
1

Hello everyone,

I am currently experiencing an issue with my 3D prints where the tiles seem to break from the upper part just by taking them off the print bed. I am using a Bambu Lab Carbon X1C printer and printing with Formfutura Regular Antracit Grey PLA filament.

Here are my print settings:

  • Infill: 20%
  • Walls: 3 (I’ve also tried with 2 walls and 15% infill, but encountered the same issue)
  • All other settings are at their standard values.

I have never faced this issue before and would appreciate any insights or suggestions on how to resolve it. Attached is an image to better illustrate the problem I’m facing.

Thank you in advance for your help.

Try Repairing the STL I use Formware sometimes the models have bad meshes

I’m curious if you might have a small clog? Wouldn’t hurt to do a nozzel cleaning… just my thoughts.

Hi Anthony, thak you for your reply I’m using a 0.4mm , but it’s woring very fine, Ass I just pringed very fine ttrpg furniture… but I’ll clean it tomorrow

Put the fences on in, lets say, the X direction. When done, flex the printbed only in the Y direction so it doesnt stress the fences as much.

Hi William, why do you think the mesh would be bad? I slised it with babo slicer, had no errors. I do see that the walls the brake are open underneath when I remove the support, while walls that don’t break dont have a open bottom when I remove the support. What do you this is the best infill type to resolve this type of problem?

Sometimes things internally can be a mess but I’ve also had bad filament and chosen bad settings, regardless you are on a learning adventure and I don’t know who created the file you are having issues with but we all offer help based on what we are told and can see with photo’s and video’s. I would thicken the walls and increase the infill maybe look at a different infill type? It’s odd they all break off at basically the same point like the interface doesn’t exist

Hi CHris, thank you for your help

how do you do “fences on in,”?

kind regards,

Hi William, I just upscaled the model to 108 % wide and 125% high, the 100% works perfect and also let say 50% of the same models don’t have this issue, so it’s like really randomly, very stronge.

What I mean is this: Put the model on the buildplate in the X direction.
When done, flex the printbed only in the Y direction so it doesnt stress the fences as much.

Also, make sure you use glue stick on the buildplate before printing.

Maybe poor layer adhesion. 3 walls & 20% infill is not super strong & where it broke would be a weak point from the looks of it. I would run a temp tower to verify layer adhesion.

Looks like poor layer adhesion when you go from long time layers to quicker layers. This implies either a print temperature issue or a cooling issue. Make sure you are printing with the door open and if possible the top cover removed. You can also play with the fan settings and min layer time settings or just slow the print down altogether. Extra walls would also help.

Hi chris, very good tip, will do that, but even a removed piece, the wall just came loose with a small pull, so this should not be allowed to happen. good tip tnx

az Cubs, thank yo for the tip, will try with all open next print. very good insight, because indee some poster on the plate with 10+ walls don’t has that issue at all. So can be indeed a temperature difffertence (current flow air) difference. will try like you said
