  • New Materials

    Early on I experimented with a few different filament materials -- PLA, PETG, OBC, Nylon. I have been printing PETG almost exclusively of late, with occasional use of PLA for parts that won't see any stress.

    I am aware that there are a number of exotic filaments available. I'd be interested to hear from folks who have found one of those less-well-known materials to be especially useful.

    Some of the guys seem to like carbon fiber filled PETG or similar. I haven't tried it, though. You'll need a hardened steel nozzle for it.

    You printed Nylon with a PTFE lined hot end, or have you installed your all metal conversion?

      Cf-Petg is my go to, light and rigid and files nicely.
      I'd like to try TPU for flexible parts and I must get a roll of Prusament PC blend (polycarbonate blended with something to make it easier to print) which is supposedly super tough.

        PTEG is what I use for chassis. The stuff is bullet proof in this application

          Somehow I forgot to mention that I am also printing a lot of parts in TPU (ThermoPlastic Polyurethane). Both flexible and extremely tough. One of the easier materials to print. Hot end 225C, bed 50C. Recommended.

            TPU is cool. What, specifically, are you printing with it?

              Things I have printed in TPU...

              - Snap-on insulators for 9 volt batteries, also for my tire cleaning blocks
              - 1/32nd front wheels with integral tires
              - an add-on to my Slot.It controller that makes it more comfortable to grip
              - grommets for electrical cable pass-throughs
              - 1/32nd car cradles for my pit box
              - Wiha tool organizers for my pit box
              - a stopwatch clip for my pit box
              - an X-acto knife clip
              - a clip for my torque-limiting allen tool

              Basically anything that needs to be a bit flexible...
