Customizable 3D Printable Timing Belt
Timing belts are excellently suited for transmitting forces over distance. With differently toothed pulleys you can also transfer forces and adapt them to different applications. Compared to gear transmissions, toothed belts are quieter and smoother and offer more design freedom.
Unfortunately, it can be difficult to get timing belts in the required length. Therefore, many people print their timing belts from flexible materials such as TPU. After manually designing the third timing belt, I decided to create it generatively.
Thankfully it is effortless to create generative forms with user data in Fusion 360. Moreover, it´s even easier to modify these generative designs.
Just download the File, open the Modify tab and select Change Parameters ∑ . In the parameter window, you can adjust all variables to your requirements. I would recommend setting the BeltThickness parameter to a multiple of the line width (e.g. 120% of 0,4mm Nozzle = 0,46mm line width * 3 = 1,38mm)
- Teeth Number
- Belt Thickness
- Belt Height
- Tooth Offset (tolerance compensation)
Quick tip for TPU printing:
- Set Z-Seam to shortest
- use low layer heights (<0.15mm)
- and/or slow down (20-30mm/s)
- Travel as fast as possible
- use coasting if available
- reduce retract speed
