I’m having some trouble printing with PVA on my ffcp. The PVA is not sticking to itself. I’m seeing if I can change the speed of the print. How do I change it so that it prints at regular speed for the object and then 60 mm/min for the support structure?

I think you need to double check the quality of the 3D printing material you obtain. Some low-quality materials cause a sticking problem more often than not.

Also, check the temperature settings of your 3D printers. This could also be a probable trouble.

What slicer are you using?

If you use simplify3d you can set specific speeds for each layer if you wanted to for each material individually. Try running the pva without the cooling fan on if you are using it.

If you are using FlashPrint, under advanced options, support, you could setup the support print speed

Hi, I would check the hot end temp setting for the PVA, you might need to raise it by 5 degrees. As I have found when the material won’t stick to print bed, raising the temp helped it stick, filament tends to shrink as it cools.
