TPU Tire Profile & Setup on Bambu A1

I would like to get a topic that is easy for new makers and existing to share TPU Tire profiles on different machine types with the best results for different TPU brands.

I’ve heard people say they like Ziro, Geetech, but I haven’t heard anyone say and Bambu based TPU such as TPU 95A, or AMS TPU.

Please share horror stories and successes.

Make sure to include print time and any photo’s if you have them.

I’ll make a separate topic for P1/X1 and P2/X2

This is the only thing that has worked for me to keep the TPU dry and reduce the strain on the extruder that causes under extrusion. The cereal box has a roller with desiccant in it, keeps it at 10 RH. The empty spool helps the tpu get up and over with no sharp bends. The black cable needs to be kept from getting under the upper brace or it will hit your top cushions and drive you crazy because you can’t figure out why the bottom of the cushion printer great and then the top, not so much… my cable was hitting the cushion.

This is my setup for A1 Mini with off-brand 0.8mm nozzle from Amazon. I think it would be the same for A1.

I feed it directly from dry boxes; I rarely actively dry it while printing, but this setup is convenient for storage. I have my A1 mini in Prusa Mini enclosure. They are getting along, and I’m hoping they will produce an offspring that will rule all 3D printers. I removed most of the PTFE tube leading to the extruder to make loading and unloading easier. I use this printer and Prusa MK3 exclusively for tires; it takes ~21 hours for a set of 4.

Thank you for sharing those settings, I’ve printed most of the chair at 0.6mm, but think will switch to 0.8mm just for tyres, that’ll cut down some time. Using Bambu 95A HF so there shouldn’t be much problem.

Thanks you for so much collaboration and sharing!

I not get the sense the longest time in the build will be the tires. Thanks again. :two_hearts:

I’ve used Tecbears TPU and Hatchbox TPU on my A1 Mini with a smooth PEI plate. I print directly from a Polymaker Polydryer through a PTFE tube. I use the GENERIC TPU profile in Orca Slicer (probably the same as in Bambu Studio). I add fuzzy skin to the outside of the tire where the kiddo’s grip would be. Print time is 5 hours 8 minutes. I print one at a time to minimize the loss if one fails. I haven’t had any failures yet.

@Charles how did you add fuzzy skin to only the outside grips, and not the dovetails?

I think OrcaSlicer has a “Paint on Fuzzy Skin” button where you can select specifically where you do and do not want fuzzy skin. Probably Bambu Studio has it too.

  1. Select the tire
  2. Select Paint-on fuzzy skin button (or press keyboard shortcut h)
  3. Select the fill tool under Tool Type
  4. Click once on the outside

The model should look something like this:
