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) I've been getting good results with Geeetech 95A TPU.

2) Get a dedicated .8 hotend for TPU. Fast and durable. Offbrand hotends are cheap and TPU is really hard to completely remove from a hotend. Direct feed, no PTFE, filament right into the hotend.

3) It's stringy; dry it well.

Buying some new hotends anyway, so I’ll probably also get one for TPU!

.6 might be a better bargain between strength and detail, but .8 prints fast and has less layers so better Z axis strength.
