Walk through any FPV pit and you'll see two kinds of printed plastic: soft, rubbery TPU hanging off the back of every quad, and the occasional matte-black carbon-fiber bracket on a long-range or commercial build. They are not interchangeable. One is designed to bend, the other is designed not to. Picking the wrong one is how you end up with a camera mount that snaps or a GPS mast that droops.

This is a plain-language guide to what each material is good at, where it fails, and which parts on a typical quad should be printed in which.

TPU 95A: the crash material

TPU (thermoplastic polyurethane) is a flexible plastic. The "95A" is a Shore hardness rating, roughly the feel of a skateboard wheel or a firm phone case. You can bend a thin TPU part with your fingers and it returns to shape.

Where TPU shines

Impact absorption. A TPU camera mount deforms in a crash and springs back instead of cracking. That protects the camera and often saves the mount.
Vibration damping. Soft mounts for transmitters and cameras reduce jello in your footage.
Grip. TPU holds antennas, straps and GPS modules by friction without extra hardware.
Layer bonding. Printed TPU bonds well between layers, so parts don't split along the print lines the way brittle plastics can.

Where TPU falls short

Stiffness. A long TPU arm or mast will wobble. Anything that must hold a precise angle under load needs a stiffer material or a much chunkier design.
Dimensional precision. TPU prints well, but very fine features and tight press fits are harder to hold than in rigid plastics.
Weight for a given stiffness. To make TPU stiff you add material, and material is weight.

TPU 95A is part of our material lineup. Like any filament it moves in and out of stock, so check the quote page or the part page for what is available today. When TPU is in stock, it is what we recommend for crash parts.

Carbon-fiber nylon: PA6-CF and PAHT-CF

These are nylon polymers filled with chopped carbon fiber. The fiber makes them much stiffer and lighter for their strength than unfilled plastics, and gives them a matte, slightly textured finish that hides layer lines well.

PA6-CF

PA6-CF is the stiff, light workhorse. It suits brackets, standoff adapters, payload mounts, jigs and even arms on experimental frames. Like all nylons it absorbs moisture from the air, which makes it slightly tougher and slightly less stiff over time. Parts living in very wet conditions are better in another material.

PAHT-CF

PAHT-CF is a high-temperature nylon blend with carbon fiber. It keeps its shape at temperatures that would soften PETG or ordinary nylon, and absorbs less moisture than PA6. It is the better pick for parts near hot motors or ESCs, or for drones parked in the sun on a black car roof.

Where carbon-fiber nylon falls short

It doesn't flex. A stiff part transmits crash energy straight into whatever it is holding. For a camera, that is the wrong behavior.
It can fail suddenly. Pushed past its limit it tends to crack rather than bend.
Cost. Carbon-fiber filaments cost more than TPU or PETG, and the price on our instant quote reflects that.

Heat: the factor most pilots forget

A quad sitting in a car in summer, or a commercial drone flying all day over hot ground, sees more heat than you'd think. Lower-temperature plastics such as PLA soften well below the temperatures a parked car interior can reach. TPU handles everyday heat but gets softer as it warms. PETG is fine for most flying but is not a high-temperature material. If a part sits next to a motor, an ESC or a VTX that runs hot, or needs to keep its shape in direct sun, PAHT-CF or another engineering grade is the safer call. Our materials guide compares heat resistance across the whole lineup.

Part-by-part: what to print in what

Print these in TPU

Camera mounts and pods, including DJI O4 Pro mounts.
Antenna mounts and holders. See the antenna mounts collection.
Arm guards, bumpers and front protectors, such as the Mark5 arm guards.
Landing feet and gear. See landing gear and legs.
Action-cam mounts that bolt on top. A little flex protects the camera. See GoPro and action cam mounts.
Battery-connector caps, such as the XT60 caps set.

Print these in carbon-fiber nylon

Payload brackets and drop mechanisms on commercial or utility drones.
Long GPS masts that must stay upright in flight.
Stack and standoff adapters, spacers and frame-reinforcement plates.
Parts mounted close to motors, ESCs or hot transmitters (PAHT-CF).
Larger airframe parts on platforms like F450 or X500-style frames, where stiffness matters more than crash flex.

Either can work

GPS mounts on a 5-inch: TPU for freestyle, CF nylon for a long-range rig that rarely crashes.
Receiver holders tucked inside the frame: TPU for simplicity, PETG or CF nylon if you need a crisp shape.
Whoop canopies: TPU for durability, or PETG if you want the lightest possible shell and accept that it may crack.

A note on PETG and PETG-CF

PETG sits in the middle. It is stiffer than TPU, cheaper than nylon and easy to print accurately, so it is a sensible choice for test fits and for parts that are protected inside the frame. PETG-CF adds stiffness for budget brackets. Neither is a good crash material, and neither is a high-heat material. Our catalog prices are listed in PETG because it is our everyday baseline. You choose the material, color and quantity before checkout.

Ordering printed FPV parts

FAQ

Is TPU strong enough for an FPV camera mount?

Yes. Strength in a crash comes from flexing, not from rigidity, and TPU 95A is the standard material for printed camera mounts for that reason. A well-designed TPU mount holds the camera angle in normal flight.

Why not print everything in carbon-fiber nylon?

Because it doesn't bend. On parts that take hits, a stiff mount passes the impact into the camera or cracks. Carbon-fiber nylon is for brackets that must hold shape, not for bumpers.

Does carbon-fiber nylon interfere with radio signals?

Carbon fiber is electrically conductive, so it is good practice to keep antenna elements clear of carbon parts, the same advice that applies to a carbon frame. Antenna holders are better printed in TPU.
