I’m trying to print Marvin, and every single time happens the same. It’s like if the plastic retracts and curves itself. I guess it’s something I do wrong, not the machine, but I can’t hit the nail on what’s the problem.

I tried adding support, turning off the fans, turning off the heatbed, printing slower and faster, with different infills (even 100%, which gave not-so-ugly results).

Does anyone has a clue on what could it be?

Thank you very much in advance.

Mauricio Ferrari.

Edit: It’s printed in PLA

Hey @ReynoldsWill, what printer do you have? Can you also share the settings you’re using?

I have a Kikai M11 (It’s an Argentinean machine) And I tried from .1 to .3 mm layer, .8 shell thickness, 20, 50 and 100% infill and 20, 30, 40 and 50 mm/s speed. On most tries I used Cura, but I used Slic3r twice with the same results.

You need a fan ! Print at 200°c for PLA get a desk fan on the desk the printer is on and print around 45-50mm/s about 20% fill with a layer dwell time of around 5-7 seconds

Fully agree with this, maybe up the min layer time to 10-15 sec…

Thee problem is that it’s not a desktop machine. It’s an industrial one. Its case is fully closed.

As for Marvin, I just changed to ABS and worked pretty well. With PLA this only happened with Marvin, everything else I tried to print came out as I wanted.

Thank you for your help! :slight_smile:
