POLYURETHANE not plastic he can make molds and such with this.

There's literally hundreds of the items I have mentioned for sale right now. They make intake manifolds out of plastic these days.

Heres a perfect example. Daystar Part KJ01003BK - Polyurethane Motor Mount - Fits 1967 to 1992 YJ Wrangler and CJ - 4 Wheel Drive

85$ for what amounts to a urethane block with screws in it.

That way the rear was as firmly planted as possible but I wanted some play with my motor trans and steering so I got poly.

Daystar Part KU09017BK - Polyurethane Bump Stop - 4 Wheel Drive

Those are another good example. People use Polyurethane for EVERYTHING. These 3D printers can hopefully help lower costs

FYI, polyurethane is a plastic.

The use of elastomeric polyurethane for vehicles is not news to me, so I don't need to Google anything. I have elastomeric polyurethane sway bar bushings on three cars, suspension bushings on two (including subframe bushings on one), and engine & transmission mounts on one. I also have Johnny Joints on my BMW's thrust arms (not that these are relevant to this discussion).

You essentially admitted my point on the wheel spacers when you said "I wanted some play with my motor trans and steering so I got poly." That's the issue -- there would be deformation and play.

Elastomeric polyurethane is what is required for the load-bearing items we're talking about, which AFAIK is not 3D-printable with current materials/equipment available to the masses. If the "urethane" the OP is using is indeed elastomeric polyurethane, then I'm wrong.*

*Except for the wheel spacers
