3d-printed valves and fittings!
Yes you can 3d-print solid TPU.
It is actually a common material in the 3d-printing world.
TPU Filament is available in a variety of colours and flexibility.
I have allready successfully 3d-printed a tube/fitting for a top-up valve.
The part was designed in Fusion360. The fabric was then ironed on the printed part. TPU on TPU. The printed material and the TPU fabric made a very strong bond.
TPU is usually printed at 220-240 Celsius.
So if you have a 3d printer or a friend that owns one or even access to a Fablab this might be someting for you.
If you have a good idea for a part please tell me. I might work it out and share the files on Thingyverse.
A bit more elegant alternative for connection Inflation Bag/Boston valve for example… hmm
