3D Printing Drone Parts: TPU Mounts, PLA Frames, and Print Settings
A 3D printer is one of the most useful tools an FPV pilot can own. When a camera mount snaps or an antenna holder breaks, waiting days for a replacement part is no longer necessary — you can print a new one in an hour. From flexible TPU mounts to rigid PLA frame plates, printed parts have become a core part of how modern drones are built and repaired.
This guide covers which filaments to use for which parts, the drone components worth printing, and the slicer settings that produce strong, reliable results.
Choosing the Right Filament
The two filaments that matter most for drone parts are TPU and PLA. TPU is a flexible, rubber-like material that absorbs vibration and survives crashes — it is the gold standard for camera mounts, antenna mounts, and landing skids. PLA is rigid and easy to print but brittle, so it is better suited to low-stress parts like GPS holders, wire organizers, and cosmetic covers.
For structural parts that take real load, consider PETG or nylon. PETG is tougher than PLA while remaining easy to print, and nylon offers excellent impact resistance at the cost of more demanding print conditions. Carbon-fiber-filled filaments add stiffness but require a hardened nozzle.
Must-Print Drone Upgrades
Camera mounts are the most commonly printed drone part because they are the most commonly broken. A TPU mount printed at the right size holds your FPV camera securely while isolating it from vibration. Antenna mounts and VTX holders are equally popular, keeping fragile video equipment firmly in place through hard landings.
Landing skids and prop guards printed in TPU protect both the drone and whatever it lands on. Motor guards and arm protectors add a thin cushion of plastic that absorbs impact energy. For freestyle pilots, a printed GoPro mount is a cheap way to add a durable action camera setup to almost any frame.
Print Settings for Strong Parts
For TPU, print slowly — 20 to 30 millimeters per second — with the nozzle at around 225 degrees and little to no part cooling. More walls matter more than more infill: four to six perimeters give a flexible part most of its strength and resilience. For PLA and PETG structural parts, use three or four walls and 40 to 60 percent infill.
Orientation matters as much as settings. Print parts so that layer lines run parallel to the load, and avoid relying on small horizontal overhangs that will snap. A brim or raft helps TPU stay stuck to the bed, and a heated bed set to 40 to 50 degrees prevents warping on larger prints.
Fitting Printed Parts to Your Frame
Printed parts rarely fit perfectly on the first try, so plan for a little iteration. Measure your frame and camera dimensions with calipers, add a small clearance of 0.2 to 0.3 millimeters, and test-fit before committing to a long print. Sanding or a quick pass with a deburring tool cleans up rough edges.
Keep a small library of your most-printed parts saved as STL or STEP files so you can reprint a broken mount in minutes. Once you have a workflow down, you will find yourself designing and printing custom parts for nearly every drone you fly.
