Have you tried Rulon and Fluorosint as PTFE coupler replacement materials?

Recommended Posts

Out of curiosity, a question to the Ultimaker developers: have you ever tried "Rulon" and "Fluorosint" for the PTFE couplers?

Rulon is an enhanced PTFE material, with higher mechanical and temperature resistance than normal PTFE (some sources say 260°C, some say 288°C max continuous temp). It is used for high performance seals and bearings. Being a PTFE-based material, low friction and self-lubricating, it might also work well with PLA?

Fluorosint is PTFE filled with mica, with one version going up to 315°C max continuous service temp.

I stumbled upon this, after reading the recent post by gudo on using PBI (Polybenzlmidazole, Celazole) to replace the teflon coupler. When looking up PBI, I also found these materials which may be a lot easier to machine.

See:

If you have tried them, how wel or how bad did they perform? If not yet tested, it might be worth asking a few samples?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
