I have printed gears in high detail resin, they were poor at best. What material would give me a better result? SLS or maybe carbon fiber reinforced nylon?

What’s the speed and load? what type of gears? what size? too many blanks to get the right answer :smiley:

Speed is about 2500 rpm, it is spinning a turbine, dual and large gears, i would say about 4x8inch

Depending on the detail required, SLS Nylon might be good, otherwise you could use an FDM Nylon printer. Worst case you could even use laser-sintered metal.

Hope this helps,

2500 rpm is very fast.

I would be concerned with heat generated while spinning against another gear.

I’ve only build chain drive gearcases.

I always use metal gears until the reduction is less than about 300 rpm.

Remember, you are working on thermoplastics that will melt if the temperature gets too high.
