Here’s a print I did of Hamstah’s planetary gearhead that I printed with PLA and PETG. Because they don’t stick to each other, I could reduce the clearance between the gear teeth to zero to create a zero backlash gear reducer. Seems like this could be useful in all sorts of print-in-place designs to keep tight tolerances between moving parts.

Sure solves a few problems but also means you need a dual head printer.
With just a P1 or so this method would use a ton of flushing cycles…
Or did you get around this with just a single extruder and hotend?
Yes, I did this with my H2D. With any other Bambu printer, you’d of course need an AMS and have lots of waste, just the same as with a multicolored print. But if you really need a zero clearance fit with something that can only be done print-in-place, like this herringbone gearhead, then it seems like the only way to go.
First of all, great application! Big fan of your work!
This isn’t entirely true though, multicolor doesn’t require 100% flush, petg/pla does. I think there might even be a factor 10 between them to get good results.
Still, loving the application! I need a gear linkage piece for my 2cv and this just might do the trick!
Good point. I hardly ever do multicolor on my X1 as I can’t stand the waste, and I never even thought about the extra flushing required for material switching. I guess it all depends on how desperate you are to get close tolerances.
