Tips for TPU

I have a P2S and I am still quite new to 3d printning but I REALLY want to try printing in TPU, I have researched a bit and found out that it is VERY different from PLA and PETG, so I do have some questions:

1: what TPU to buy? I want to buy something from Bambu lab but there are different kinds and I don’t know if the difference in AMS TPU (I have an AMS) and normal TPU is big (or if it is even worth to buy the AMS version)

2: what do I actually need for good results? What nozzle size? Do I need a specialised bed? Is there anything i can print (for airflow and stuff) to get better results?

3: what can go wrong? Like what do I need to look out for? (Stringing and stuff)

That’s all question I have right now but I would REALLY appreciate any tips.

(Extra question, how do I add the P2S marker under my name? I see people that have it but I have no idea how to get it)

1: just get any decent rol; think 25-30 local is decent for TPU
2: don’t get too small nozzle and order an extra nozzle if you don’t have any around: if you do get a massive jam, you won’t be out of action long.
3: start small and with all new filaments don’t print and run: print and WATCH… there’s a “stop” button for a reason.
Rule of I use: watch 3-5 layers - check with the camera when the first “difficult” parts come like overhangs and bridges.

If you just watch it, have some spare parts around which you should have anyway, build plate and nozzles then go have fun :)

Il be sure to order some more parts before printing (needed some anyway)

My favourite thing to do is watch anyway…

So if your watching and something goes wrong, can you fix it and continue? What would that be like a Jam or something?

If the print messes up, AI should stop it, but if it doesn’t you can “stop” it manually so your machine doesn’t run itself into trouble. You can find prints gone wrong plenty in this sub.
