3d printed gears question.
Posted: Sun May 22, 2022 6:17 pm
Hey G'day people,
I'm 3d printing an orrery which of course involves Gears. Imagine... lol..
My question is for those that print gears with an FDM printer (I could do this with my resin printer but I like to do it the hard way).
How are most of you printing the gears, with a rim/brim/raft?
If I print using my resin printer gears are perfect every time, only problem that I come across with resin is warping. I need to find some high tensile resin to try that out and see if that is subject to warping.
The post processing is murderous, printing large gears isnt an issue but printing fine gears seems to be, particularly with curling of the tips.
If I print a brim its not an issue but then the post processing and peeling off the brim becomes a pain.
What I would like to do Ideally somewhere along the line is buy some involute gear cutters and set up my rotary axis to make gears using brass. But I haven't found a method/shaft that I can use with my spindle to accomplish that yet.
Any tips and suggestions would be appreciated.
I never knew chasing my own tail could be so much fun :P
Cheers and greetings from the colonies downunder.
