Testing a 3D Printed Cycloidal Gearbox Design
A 3D printed cycloidal gearbox design has been tested for its performance and efficiency. The design was created to fit on NEMA 17 stepper motors and aimed to improve upon the planetary gearbox alternative. The results showed a 92% efficiency and reduced noise compared to the 3D printed planetary gearbox.

Testing A 3D Printed Cycloidal Gearbox Design No comments by: Maya Posch August 1, 2026 Title: Copy Short Link: Copy Cycloidal gearboxes are a recurring theme in the hobbyist space due to the performance their promise in a compact package. They are capable of taking in a high-speed input and reducing it down to a set ratio with very low backlash, which theoretically makes them perfect for a wide range of projects where size and weight matter. Correspondingly, [Advanced Hobby Lab] has been tinkering with a 3D printed design to fit on NEMA 17 stepper motors. For [Advanced Hobby Lab] the primary goal was to check that his cycloidal gearbox design was a real improvement over the planetary gearbox alternative.
