Re: HO scale 3D printed D&RGW gondolas

The material looks like Shapeways hi-definition acrylic:

A reasonably nice material for HO scale parts; I did a set of murphy car ends using this - took paint well. The trouble is that the material won't print in small cross sections, so fine details are out. I wanted some working switch stands from the material, but had to bulk them up so many times the thickness of proto-dimensions I gave up. The car ends have cupped a bit over time, but always bend back into the flat shape they should be. Glued in place and painted, they blend with styrene and hold their shape. I think it offers interesting opportunities for HO trucks, btw, because it is very strong, but the course details and the cupping both worry me.

Since they are black, I suspect that he is casting his own cars at home. Hence the crude look. If he was using Shapeways and having them made in Frosted Ultra Detail, they would be translucent and the detail would be much finer.

For $65 they are awfully crude. That brake chain (?) looks like it’s a foot thick (yes, I’m exaggerating).

It is a nice looking car in the photos. I am tempted to buy one. Has anyone on this list tried these?

I wonder if this (3D printing) is the future of modeling, replacing resin casting. I've heard it said that it is hard to find people who can do good castings. Maybe we will end up replacing the hard-to-find resin casters with hard-to-find 3D designers.

Hello Group,

I happened across this seller on Ebay, offering HO scale 3D printed 42' and 46' Rio Grande GS gondolas. Here's a link:

If the link doesn't work, the seller is Bonsall Scale Car Shops. I haven't purchased any of these kits, so I can't comment on the quality, but I know models of these prototypes have been long desired by many folks on this list, and I have not seen them discussed on this list.

They look nice in the pictures, and they are certainly more economical than the W&R model! I wonder if the seller is a member of this list?
