Great Filament for RC Controlled Planes and Drones

#1

I want to print a drone frame, using a filament that I can use with my Prusa I3 MK3 3d printer, that has the following features.

  • UV resistant
  • Heat resistant (Ie: will not melt due to temperature)
  • Flexible
  • Shock resistant
  • Produces no fumes
  • Can be easily stored
  • Parts can be easily glued together with CA Glue, or a similar glue.
  • Can be sanded and painted.

I do not want to use PLA as it will melt in the hot sun, PETG does not have all the above features, ABS produces fumes, and should be printed in an enclosure.

I an now looking at TPU filaments, and would like to know if anyone has any experience printing and flying planes and/or drones using TPU, and if so, which brand they used.

TPU wont be suitable even for FPV Racers.

What you need is maximum stiffness with low weight. You can use PLA or PETG as the design will influence the thermal abilitys and motors shouldn get hot as well if a correct layout is used. That might be different for FPV. You ideally want to look at a combined design with cfg gfk nfk composites in certain areas and the more difficult parts printed. You could maybe use TPU as a bumper material in certain areas to minimize impact. The better way would be easily interchangealbe arms etc.

I wonder if this question was related to the recent video Prusa released with a small printed drone :wink:
