needing a tube that is flexible, elastic, and strong for passing 120 degree C fluid to heat sma wires which is housed inside of the tube. end up with tpe (i use sebes). after almost 30 different designs and trials, end up with a spiral that can be stretch straight. combined with sma and heating/cooling fluid (oil is used for this instance), the whole combination works like a muscle with tendon and ligaments. a 220 x 150 print bed can produce a tube that is almost one and half a meter long, well worth the effort. when printing with soft materials like tpe, if the feed gear is too tight, the filament would feed through, as some one mentioned on a forum. i use a piece of plastic to hold down the spring lever on the feeder to reduce the force of the spring. it works nicely since. i really own it to the one who mentioned it. almost give up using the tpe. it is the best material for strength so far. elastic and much stronger than silicone.
