# What filament is best for drones/RC parts?

Prusament PP Glass Fiber lists an extruder temperature of 245 ± 10 °C (473 ± 18 °F). The product page, read 26 October 2026, says hobbyists may find it useful for drone parts. That is the page's sentence.

There is no best filament in the supplied comments. Prusa's own PP Glass Fiber page names drone parts as one use, next to a hardened nozzle and a PP sheet. A light foaming PLA and a shore-85 TPU are different tools. [Foaming PLA](/answers/lightweight), [carbon fiber](/answers/cf), [flexible filament](/answers/flex), and [strength](/answers/strength) are the pages this one should not pretend to replace.
## What the pages actually publish

[Prusament PP Glass Fiber](/brand/prusament/pp-gf), read 26 October 2026, lists an extruder of 245 ± 10 °C (473 ± 18 °F), a bed of 95 ± 10 °C (203 ± 18 °F), enclosure not required, a hardened nozzle, and a print surface of a PP sheet or smooth PEI with PP tape. The page says lightweight and says hobbyists may find it useful for drone parts. It does not state a density, and it does not call 138 °C (280 °F) a heat-deflection temperature. That 138 °C (280 °F) line is labeled high-temperature resistance, with no load. The catalog's Open Filament Database cell is 240–250 °C (464–482 °F) and 90–110 °C (194–230 °F). Keep them apart.

[PolyLite LW-PLA](/brand/polymaker/lw-polylite-pla) lists 190–210 °C (374–410 °F) and a bed of 25–60 °C (77–140 °F). Heat-deflection is 54 °C (129 °F) at 0.45 MPa and 50 °C (122 °F) at 1.8 MPa. [Bambu TPU 85A](/brand/bambu-lab/tpu-85a) lists 200–250 °C (392–482 °F), a bed of 30–35 °C (86–95 °F), and shore 85 in this catalog. SUNLU's PP page, read 26 October 2026, lists a density of 0.9 g/cm³ and a PLA comparison of about 1.23 g/cm³. The order is a glass-filled polypropylene the maker mentions for drones, a foaming PLA, and a TPU. It is not a frame ranking.
## What the community says

[a Reddit thread in r/3Dprinting](https://www.reddit.com/r/3Dprinting/comments/xzmlsp/) prefers epoxy and a modeled joint for a PLA hull.

[a Reddit thread in r/prusa3d](https://www.reddit.com/r/prusa3d/comments/1mj3p8x/) says polypropylene is the lightest plastic by a significant margin.
