Tpu printing issue please help
Hi everyone, Please help — I can’t figure out what’s causing these print errors in my slicer. The filament is Sunlu TPU, brand new out of the box (so it shouldn’t need drying). I’m using a 0.8 mm nozzle, with a layer height between 0.2 and 0.35 mm, and a print speed around 25 mm/s. No matter what I try, I can’t get a clean print without these failures — the issue always appears in one corner.
Any advice or suggestions on what settings I should adjust would be greatly appreciated!
Whilst I suspect you do have a geometry problem in the corner it is being magnified and masked by moisture; never assume new filament is dry.
Dry your filament and try again. If problems persist first try rotating the print on the bed - if the problem moves with the print it is probably something in the file/settings, if it stays in the same position relative to the printer it may be a cooling issue.
If it seems to be a file issue save your project as a .3mf file
Files > Save Project as
Zip the .3mf and post it here. It will contain both your part and your settings for us to diagnose.
Cheerio,
