your part is underextruded, might not matter for this application but if you take this profile for critical parts like a lid to seal off liquids, it will just seep through the gaps, happened to me. Increasing walls does not help, i really needed to change flow ratio, temps and especially speeds to get rid of the gaps. It also helps to roll off the filament so the direct drive gear only has to work on extruding and not do double duty by also pulling the filament from the spool. Bambus backside spoolholder has a lot of friction that usually doesn't matter for stiff filaments, but soft TPU really benefits from such strain relief
You can print tpu on the textured plate 😂 just cause it dosnt say it on it, dosnt mean you can’t use it 😂😂😂😂 Literally hundreds of tpu prints on my textured plate!
I've found on all the Bambu printers I've used (A1, P1s and X1C) they all need the retraction settings increased to print TPU cleanly with no stringing.
I have printed some 95A without any adjustment to the retraction settings on my X1C and I didn't get any stringing, then again I suppose different TPU products need different retraction settings but for me the default settings were just fine
i dont own a bambu, but on my printer i found that NO retraction at all gave very good results... does this not apply to bambu? im thinking about getting the p1s combo for printing my tpu stuff
Best to run TPU directly from an active filament dryer, start with 6 hrs of drying then run. Settings other than standard have less effect on quality, dryness has the most effect.
I have used tpu for years and the bed did not matter (glass or Pei as long as it was at the right temperature(80c+) and clean. And all that faffing about to load it was ridiculous.
Happened to me too. I cut a piece of ptfe tube about 1 and a half inches long, sanded the edges of the cut side smooth, and inserted that into the back of the machine after disconnecting the tube feeding from the ams. I then fed my tpu from a very loosely (re-coiled) spool. I also increased the temperature to 5 degrees above the recommended temperature for printing
I've been wondering about how well the X1-Carbon printed TPU. Did you have to lower the print speed or does the slicer do it when you select TPU as the filament?
The slicer lowers the speed by default under Generic TPU, but for Ninja Flex I had to lower it more. It's under the settings for the filament max volumetric speed.
Dry your filament. You don't need to change plate. Pei works best for every type of filament. Get the high flow tpu and print at high speed perfect clean prints every time.
may i help You? i don't know your filament but with ninjaflex enter the recommended filament temps and modify the Flow ratio to 1.05 in "filament settings". After that go to the "Speed" tab and start with 20mm/s for all the actual print speeds. Acceleration and travel can be faster. if this prints fine then you can always try faster speeds. If your TPU is stringing or bubbling it needs to be dried (this takes hours because you have to dry only at around 80° Celsius) hope this helps
