Does anyone know what plastic the factories are using to prototype arms and such for 1/8th buggies? Any help would be appreciated, and also where to get it

Thanks

Thats a trade secret they dont want you to know,
Im sure its not your average plastic I know some are even mixed with glass

Delrin has always been popular for prototyping.

I imagine they use SLA/polyjet type 3D printing systems for the quick fit/feel prototypes...not sure how well these materials would hold up to full speed runs. I saw a Proline video a while back showing their 3d printer in the background that they used to make wheels and such.

I've used a number of 3d printed prototype parts in my career (not r/c) with plenty of success.

Thanks for the info guys

I might be wrong here but I dont think that the stuff we call plastic actualy contains any plastic. I think its some sort of carbonreinforced nylon, but what do I know

Yes, fiber reinforced PLASTIC (nylon is a plastic). But, this is what they use for the final production part. Making prototypes before the molds are made is a different story.

Many use Delrin and machine the parts from it. Works quite well.

Xray and many others use 3d printers. These parts are too fragile to run. Just used for fit testing and such.

Some, such as Capricorn are using lithographic 3d prototypes. My understanding is that these are strong enough to run, though not as strong as the production FRP part will be.
