    Hello all printing gurus out there.

    I want to print gears that will lower down the turning of my potentiometer in my actuator. Learning Fusion 360 as I was advised, I could do simple straight gears.
    But I've seen a lot of v shaped tooth on gears lately and I was wondering if it was a better design?
    The gears for my actuator will probably turning quite fast with a lot of direction change. Is there a type of gears that is recommended for that? And is PLA good enough for it?

    Thanks.

    Use ABS or Nylon for the gears, PLA will grind after while as its harder material

    ABS or Nylon, this is what I was afraid for. I have no experience with those material. But at the same time, I have no experience in 3D printing.

    Thanks for the link to the gears. I really like the fact that they explain in the tooltips all the abbreviations used for measurements. Really useful for a noob like me.

    I would HIGHLY suggest getting used to PLA printing first. Hone your printing skills, then work up to different filaments.

    Indeed, I had the intention of doing the gear in PLA first, and once working, move up to ABS. But I probably won't be ready then, because things are moving way to fast for me. I'll just have to adapt (badly) like I always do.

    what about using pre-made dented pulleys and a belt? (you can buy them for cheap in china sites, you can use the ones used in 3d printers

    best regars

    I did! But I've chosen them too small, and I am not sure yet how big they need to be. I have to measure. Since I bought my 3D printer especially for that, I'd like to use it. But it is not a bad Idea. They do take a while to get to Canada though.
