Chris_205 Posted July 19, 2020 Share Posted July 19, 2020 Morning all. So has anyone had any experience with, as the the thread title states, 3d printed spur gears? Reason I ask is that a recent investment I made I've found the spur gears to be stripped, (which was due to an accident that the seller hadn't disclosed on the ebay listing description) and I'm seriously struggling to find any replacement parts. Any feedback regarding any 3d spur gear printing experiments/experienced would be much appreciated 👍 Quote Link to comment Share on other sites More sharing options...

Alex97 Posted July 19, 2020 Share Posted July 19, 2020 Depending what gear pitch you want and how much power will be put through it. The finer pitches will be a struggle due however a larger ones shouldn't be an issue. The thing would be ensuring that when drawn in CAD it's drawn correctly as gears can be tricky to get right. What model is it going in, once we know that it would be easier to advise? Quote Link to comment Share on other sites More sharing options...

Apologies for the delayed response. I've attached images of the culprits in question! The lower picture is of the spur gears in their natural habitat.

Alex97 Posted July 19, 2020 Share Posted July 19, 2020 You'd need them printed in ABS or something stronger. Quote Link to comment Share on other sites More sharing options...
Chris_205 Posted July 19, 2020 Author Share Posted July 19, 2020 Yes that's what I was thinking also. I don't think PETG would work very well to be honest. Quote Link to comment Share on other sites More sharing options...
Tony Posted July 19, 2020 Share Posted July 19, 2020 As a 3D printer owner, I would agree that PETG won't be strong enough, and I don't think ABS won't be strong enough as well due to the extreme force in these gears. You'll need moulded gears. Quote Link to comment Share on other sites More sharing options...
Mack1 Posted July 19, 2020 Share Posted July 19, 2020 Does this look like the one? https://wheelspinmodels.co.uk/i/224132/?gclid=Cj0KCQjw3s_4BRDPARIsAJsyoLPBROypvRt9X9XOUzV_tb9rOvYjMZQz57TifBJH6oIM_tvdJqaz5_UaAtcqEALw_wcB Quote Link to comment Share on other sites More sharing options...

It will yes, it has the same part number as what is fitted to the Giga Crusher. The thin serated disc I'm unsure of though. However I'd still need the other 2 spur gears to complete the set. Admittedly I do have a full gear set on it way from Italy 🇮🇹. But if that ever strips then I'm not sure if I'd ever be able to find another set hence the nature of my post/thread 👍 Quote Link to comment Share on other sites More sharing options...

It beggars belief that plastic is used in such drive trains, as there's no other plastic parts involved. Surely it can't be put down to being a "deliberate weak point".

Mack1 Posted July 19, 2020 Share Posted July 19, 2020 If that's the one then this must be the other 2 https://www.modelsport.co.uk/kyosho-2-speed-gear-set-inferno-gt-mforce-was-gtw20-2-/rc-car-products/29710 Quote Link to comment Share on other sites More sharing options...

Unfortunately the part dont match up although they are remarkably similar in appearance. I've attached a screenshot of an exploded diagram of the gear set with their respective part numbers.

I suppose in all fairness it can't hurt to give them a stab as they're not going to break the bank that's for sure Quote Link to comment Share on other sites More sharing options...
Mack1 Posted July 20, 2020 Share Posted July 20, 2020 To me they look the same? From the leg work the k-gtw20-2 has been replaced with the k-ig109 https://hobbyfactory.fi/en/p45974/kyosho-spur-gear-set-2-speed-inferno-gt-43-46t-gtw20-2-k-ig109 Quote Link to comment Share on other sites More sharing options...
Alex97 Posted July 20, 2020 Share Posted July 20, 2020 now knowing what it's going to be used on a standard 3D printer wouldn't be able to make anything strong enough. the structor would just split. Quote Link to comment Share on other sites More sharing options...
