Picking the wrong filament is the fastest way to reprint a drone part. PLA prints easy but snaps. PETG flexes but strings. PLA+ sits in the middle, and HT-PLA Pro adds heat resistance on top. Here is how PLA, PLA+, and PETG actually compare for drone parts and accessories, and which one to buy for mounts, brackets, guards, and enclosures.
PLA: easy printing, brittle parts
Standard PLA is the easiest filament to print. It sticks well, warps little, and gives clean surfaces at normal settings. The tradeoff is strength. PLA parts are brittle, so a hard landing or a tight screw can crack a mount that printed perfectly. Use PLA for decorative parts, prototypes, and parts that never take a load. For anything structural on a drone, PLA is the wrong pick.
PLA+: the same easy print, much tougher part
PLA+ is the stronger version of PLA. Compared with standard PLA it is tougher, less brittle, and holds up better under impact, with stronger layer-to-layer adhesion. It prints at nearly the same settings as PLA, so there is no learning curve. That makes PLA+ the default choice for drone parts and accessories: mounts, brackets, camera mounts, landing gear parts, and housings that get knocked around. PLA+ filament comes as a full 1KG spool, ready to print. Anycubic PLA+ is a refill coil at a lower price and needs a reusable spool.
PETG: PLA ease with ABS toughness
PETG combines the ease of printing of PLA with the toughness of ABS. Its impact resistance is twice that of standard PLA, and it handles chemicals and water better than PLA or PLA+. PETG flexes instead of snapping, which is what you want for chassis, guards, mechanical prototypes, and drone parts that take hits. It strings more than PLA, so tune retraction, but the printed part is worth it. Anycubic PETG refill is a 1KG refill coil and needs a reusable spool.
HT-PLA Pro: for parts that see heat
Polymaker HT-PLA Pro adds heat stability to PLA Pro toughness. It prints up to 300mm/s, needs no enclosed chamber, and anneals at 100C for 30 minutes for the best heat resistance. Use it for electronics enclosures, automotive interior accessories, brackets, and housings that sit near motors or in a hot car. Polymaker HT-PLA Pro is a full 1KG spool.
Which filament for which drone part
Mounts, brackets, and camera mounts: PLA+. Guards, chassis, and parts that flex: PETG. Enclosures and parts near heat: HT-PLA Pro. Decorative parts and quick prototypes: PLA. If you only stock one filament, stock PLA+ in black and white. It covers the most drone parts with the least fuss.
All five filaments are in stock in the 3D Printer Filament category, shipped from NY, USA.
