Correct material for 3D Printing a transmission part

[AK KRAWLER]

I am going to be asking for help in having someone 3D print a few Summit Dog Carriers and need to know what the best material to print it out of would be.

What would the best material be for this? Or will it not even hold up to the pressure of use inside a transmission.

Looking for options since the LEM Dog Carrier is no longer available.

Thank you

It looks like it already exists. It's going to take a lot of abuse so I'd want it printed out of metal of some sort. You can upload this file to Shapeways and have it printed in metal for you or any other material.

Thanks, I had actually found that. This was part of the reason for my question.

I had no idea you could order them and have someone print them off the Thingiverse website... Thank you for telling me

If it is available to be made out of aluminum, that would work for me!

I don't know if you can order from Thingiverse, but you can upload it to Shapeways and order from there.

10-4, thanks.

I have contacted Shapeways to see what material they recommend.

SLA Plastic Accura® Xtreme™ 200, Steel, or Aluminum

Check out Jawstec too, they offer much lower pricing than shapeways.

The metal prints will be sintered metal. Typically with prints the bearing seats need some cleanup first but if you get a metal print I would be a little concerned that these would be hard to clean up.

I would personally choose the glass filled MJF Nylon that Jawstec offers.

Thank you sir.

I checked out Jawstec and it was pretty reasonable, actually too reasonable to pass up. I had them make up two of them and it was $7.25 + Shipping.

If they don't work out, I'm not out any big money and I will let everyone else know as well.

Still waiting on the quote back from Shapeways.

Once the parts get here from Jawstec, I will get them both fit-up to ensure they work and then head to some of the local machine shops to see what it would cost to have one made out of aluminum.

Awesome! Please let us know the quality of the parts when you receive them.

I definitely will Jato.
I did not order them tumbled or polished, so we will get to see what the raw product looks like. What I should have done, is ordered three, one raw, one tumbled and one polished. That way we could have see the difference with each on the exact same part. But alas, I wasn't thinking real clear when I ordered them. It was late at night after a long day working in the Arctic...

The bumper I ordered for my son's SCX10, I ordered tumbled. That way I can see what that actually does for it. Now that I go back and look at it, I might have ordered the bumper for an SCX10 ii Deadbolt, instead of the original...

[HumboldtEF]

I just though I'd post up what I just got from Jawstec, Its a front bumper for a LC70. I got it tumbled and the finish is pretty nice, grainy but not as grainy as the raw shapeways SLS I'm used to seeing. I used the MJF glass filled Nylon, it feels very stout.
there are a few lines in the print that aren't supposed to be there but its not too bad.




I'll use them again for sure

Nice to see options other than shapeways

Just as a follow up, I finally installed the 3D printed Dog Carrier from Jawstec and fitment was spot on, no sanding or filing required. No feedback regarding durability, due to still building the truck. I’ll post some pics soon and post results once the truck is up and running. It’ll be a while though.

[JatoTheRipper]

Good feedback on Jawstec. Thank you.

I never thought about tumbling a 3D printed part. That's a great idea.

[AK KRAWLER]

Here is a pic that shows the difference in the cog size between the stock and the 3D printed Dog Carrier. I figured in the raw finish, it should “hold” more grease on its surface. Once the truck is up and running, we’ll see how well it holds up.


Here is the high clearance bumper I had printed and tumbled. The finish looks decent, unfortunately I ordered it for an SCX10.2... and it doesn’t fit my son’s SCX10.

[HumboldtEF]

Are you sure its a good idea to grease that? I've had bad results greasing 2 speeds and locking diffs (dog gears) as they tend to prevent them from working reliable. I believe the grease can create an air lock. Maybe thats why the stock one has holes?

[AK KRAWLER]

Good point Humboldt. I’ll try it greased first and if there’s any issues, I’ll definitely report back.

[Joshs4x4toyz]

Instead of grease use a dry graphite (like pinewood derby stuff). Especially with something porous like this. It will be super smooth

[AK KRAWLER]

Well, the MJF Nylon Front bumper lasted all of about 5 minutes before something happened and both bumper mounting posts snapped right off

Definitely way to brittle for use on my son's rig.

PETG has got your back! Ive tried breaking some of my misprints, undersized items by hand, and couldnt. I made some Kyosho Mad Force lockouts with it and thinnes wall thickness is 2mm, and i couldnt break it.

Thanks for the info and I will definitely keep that in mind when I have something 3D printed next time
