![]() ![]() We’ve also seen 3D printed props before, like this effort from. With a 3D printer, it’s possible to experiment with all manner of propeller designs, and we’d love to see the best and worst designs that are still capable of flight. It’s a worthy experiment, and something we’d like to see more of. The instructions used for creating propellers in Fusion3D are available here. If you’re keen to try them out yourself, the STL file can be had here. The video notes that when printing 4 props, 2 must be reversed in the Y-axis to print a counter-rotating set of 4. ![]() ![]() We would recommend some eye (and body) protection when spinning these props up for the first time. It was noted that the props perform particularly poorly in a crash, with all props failing even in the softest of crashes. No major difference is noted between the two materials, and the quadcopter under test is able to fly with either. The props are a fairly simple 3-bladed design, which were printed in both PETG and PLA. Thinking it might be fun to experiment, decided to 3D print some props and head out for a fligh t. Selecting the right props can have a major effect on things like flight time, vibration, and a whole host of other factors. In the world of drones, propeller choice is key to performance. ![]()
