3D Printed Drone Frame: Can a Printed FPV Frame Survive Crashes?

A 3D printed drone frame can survive hard crashes if it’s printed in the right material: in throw tests by Mediocre Nerd, a YouTube channel that designs printable 1S quads, Polymaker PolyMax Tough PC came out on top of nine filaments, and a reinforced version outlasted the carbon frames he tested, at a weight cost (Mediocre Nerd, “Building a 3D Printable FPV Drone Stronger than Carbon”). PETG-based frames were the first to drop out.

AeroBatFPV, a channel that designs printed FPV frames, found the arms of his carbon-fiber-filament frame held up after many throws at concrete, metal and wood (AeroBatFPV, “Carbon Fiber vs 3D Printed FPV Frame DURABILITY Test”). Printing also lets you build shapes you can’t cut from carbon plate. Here is what creators found in builds and crash tests, plus which parts are easiest to print.

Crash Tests: Which Filament Survives?

Mediocre Nerd printed the same small frame in PETG, PETG Pro, glass-fiber and carbon-fiber PETG, ASA, PA6 carbon-fiber nylon and PolyMax Tough PC. Each weighed about 14 to 17 g (Mediocre Nerd, “Building a 3D Printable FPV Drone Stronger than Carbon”). He threw each at the ground at 25%, 50% and 75% effort, then added CNC-cut brass weights of about 25 g and repeated. His results:

• PETG variants: all dropped out at the first, lightest throws.
• Carbon-fiber nylon: bounced off the ground unharmed at first, then took damage and was out once weight was added.
• ASA: survived several unweighted throws, finishing second.
• PolyMax Tough PC: absorbed impacts and bounced, bending rather than separating; it finished first.

Against commercial carbon frames, the PC frame came close but didn’t quite win. So he thickened the arms and reinforced the high-stress spots, and the new frame took three throws into concrete, including one as hard as he could, with basically no damage, then kept going with 50 g added and at full flying weight (Mediocre Nerd, “Building a 3D Printable FPV Drone Stronger than Carbon”). The tradeoff: it weighed 25 g against about 10 g for his carbon Swift frame.

He also flew one of his most flexible early frames to test the claim that printed frames are too floppy. It flew fairly smoothly, and he pointed to Tiny Whoops as proof a frame doesn’t need to be extremely stiff to fly well (Mediocre Nerd, “Building a 3D Printable FPV Drone Stronger than Carbon”).

AeroBatFPV’s Throw Test

AeroBatFPV designs 3, 5 and 7 in frames printed in a Bambu Lab carbon-fiber filament (AeroBatFPV, “Carbon Fiber vs 3D Printed FPV Frame DURABILITY Test”). He noted PLA frames could be snapped by hand with little force, and that this was about his fourth frame material. Throwing a test frame without its top plate, the printed pillars took most of the hits and came off, while the arms held up with small dents near the motor mounts. He plans to swap the pillars for standoffs and said the top plate adds rigidity. A carbon 3.5 in frame thrown the same way kept its arms but lost a standoff and its front plate. He also switched infill from gyroid to rectilinear for better resistance to twisting.

A Full 3D Printed Race Quad Build

Engineer and YouTuber Michael Rechtin designed a printed 5 in race quad (Michael Rechtin, “Building a DIY 3D Printed FPV Race Quad”). Key choices:

• A carbon-fiber nylon center body holding the electronics and battery, with PLA arms to match a color scheme.
• Four 4 mm heat-set brass inserts so plastic threads won’t strip.
• Dovetail arms that slide into the body for a secure joint with no extra hardware.
• An FEA check: at 569 g, each arm carries about 1.4 N in a hover, and stress stayed well below PLA’s strength.

He also flagged that a plastic frame is less stiff than carbon, so arm vibration at certain motor speeds is worth watching.

Easy Drone Parts to Print First

• GoPro and action camera mounts (TPU)
• Antenna mounts and arm guards (TPU)
• Lens protectors (TPU)
• Battery pads and strap guides
• Prop guards and ducts

Tips for a Stronger 3D Printed Drone Frame

• Skip plain PLA and PETG for frames; creators had the best results with polycarbonate, ASA and carbon-fiber nylon.
• Add material at arm joints and motor mounts, per Mediocre Nerd.
• Keep the top plate and use metal standoffs instead of printed pillars, per AeroBatFPV.
• Use heat-set inserts for screws, per Michael Rechtin.
• Print arms so layers run along the arm.

3D Printed Drone Frame: Frequently Asked Questions

Is a 3D printed drone frame strong enough?

For small quads, yes, in the right material. Mediocre Nerd’s reinforced PC frame outlasted carbon frames in throw tests, though it was heavier.

What filament is best for a 3D printed drone frame?

Polycarbonate topped Mediocre Nerd’s tests, with ASA second. Carbon-fiber nylon is popular for frames, and TPU for mounts and guards.

Are 3D printed drone frames heavier?

Generally yes, which affects flight time and agility.

Do drone frames need to be stiff?

Less than many assume, per Mediocre Nerd, though a stiffer frame helps with vibration.

What should I print first for my drone?

TPU camera mounts and antenna holders.
