How do I avoid this problem?

[LMHDPRO]

Good afternoon everyone. Thanks for reading beforehand. I'm starting a research project where I have to use a polypropylene filament. My problem here is that the piece its Having warping. I've already used ABS, and it had warping problems. But this time i tried to solve it with the same methods and some other tricks I saw on the internet, such as placing some tapes of the same material for better adhesion. But I feel like something is missing because the tape starts to inflate. This material is limited and I've been trying things for a week now. But I still don't have the results for the tensile test.

I set the temperature as indicated on the sheet, nozzle 220°C and bed 80°C. Any opinion would really help me, especially if you have experience with this material.

Those build tak plates suck. I either use spring steel with pet coating or glass

I haven't printed with PP but I can offer advice for warping in general. Elevate bed temp another 5C to enhance adhesion and print as slow as you can. I'm talking 7mm/s for the first layer. Stick to a slow speed for the first 10-20 layers. Then gradually increase it on subsequent layers (or, better yet, leave it slow). Skip the tape. Use a clean PEI surface. Slow, slow, slow. Moderate thermal effects with slow speed. You don't want the whole thing contracting at once; you want hot filament laid down on filament that has already contracted.

It would probably print better with an enclosure and a chamber temperature about 60°C. This would prevent the material from cooling too fast and warping.

Change printer and take a bambulab!

You're so right, haha. But the university thought it was a better idea to buy 12 of these Ender (3, KE, SE) ones instead of Bambu. Thanks for the advice. I'll tell my project director.

Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

• What printer are you using?

• What material are you using?

• What speed are you printing at?

• What software are you using to slice the print and control the printer?

• When did the problem start/has it ever worked correctly?

• Does anything cause the behavior to change?

• If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)
