TPU 85A offers exceptional flexibility for shock-absorbing parts like grips, cushions, and protective cases.Available in neon orange and light cyan.
TPU 90A steps it up with higher hardness, perfect for durable shoe soles or RC tires. Available in frozen, blaze, white, and black.
Both filaments deliver outstanding wear resistance, ensuring long-lasting performance even after repeated bending, making them the go-to choice for high-demand applications. Check them out here: TPU 85A / TPU 90A | Bambu Lab USA Store
I think it is because of the long Bowden tube. I might be wrong. Tpu is like shoving a wet spaghetti noodle through a narrow tube. It might get stuck. You probably can get away with not using the Bowden tube and go directly into the extruder.
I want to make myself a nice pair of crocs. Crocs are so darn expensive and I always wanted a pair. Maybe I can make the roller skate mod for it too! (Link Below) https://www.thingiverse.com/thing:4927188
From my side I’ll be curious tu make trials modeling and printing light and flexible rubber soles for my sneakers with TPU 85A that should be softer than 90A
Ah yeah, that makes sense. Perhaps the difference between 85 and 90 isn’t that huge to begin with? So if I have this right, ordering Bambu’s TPU filaments from soft to hard it would look like this: 85A → 90A → 95A HF → TPU for AMS (68D)?
Simtom - I think with the new new foaming tpu we don’t even need to bother with the grades anymore.
We just need to use their (foaming tpu) chart included to match the temps for the softness. And by all accounts it prints very well on the bambu series from the comments in other threads.
While it’s nice bambu here are making new stuff, if it isn’t supported (i know it’s a typo) on the 04 nozzles which are default I question the purpose of making the “new tpu” to begin with you know? to sell more 08 nozzles? haha
I wish the foaming tpu price comes down to use that - it’s still about 25$ more than their new versions here…maybe this will drop their prices?
EDIT: why can’t they copy the alt brand and make foaming tpu which would…give the full softness/hardness range?! Then instead of us having 6 brands or types…we can just grab one and use a chart??? no???
I think this would be cool for making shoes, and with the new prusalicer changes hopefully being ported to bambu studio soon, it could be good for dual filament operations if you are comfortable with switching filaments manually eg. Shoes with pla buffer between the outsoles and insoles for more rough terrain!
My “soft” hammers have 95A TPU heads.
They can be changed easily, so I could try the 85A for a more soft touch when used in delicated printed parts.
Years and years ago (back in 2019) I designed passively vented grips for my mountain bike to cool down and dry my hands on hard trails and it really worked! I retained much more grip, even with sweaty palms. And six years later they are still going strong! I’ll have a crack at it too see if they work well with the bambu filament and I might update and upload the designs if there is enough interest or a bike/tpu contest:
For a few seconds before reading the text I was thinking “wow this guy made a pew pew silencer with TPU! I guess it’s harder to damage when dropped” lol
I want to make my own front wheelchair wheels! I wanted to do this with the TPU 95 I have at home, but this will be even better. I want to make the actuall soft part of the wheel with a internal grid so it has some bounce to reduce the bumpy feeling when riding in my chair. The inner part will be made of a strong plastic of course.
Picture of my plans and original front wheel
I know it can be done because it has already been done, but those wheels are expensive! It would be great to make something like this a free to print file
