I use silicon bronze ingots for locomotive parts. I have been using Shapeways "White Strong & Flexible Plastic" for the wax. (LOL) I am having very good luck.

The white plastic burns out just like wax..? Doesn't shapways print in wax also?

Hi John
Yes, the plastic burns out clean, but it does stink. Luckily the work shop is not attached to the house. The Shapeways wax is for small objects and is very costly.

The wax is much more expensive than the plastic. Plus, you can make only small parts in wax.
I have the driver centers machined and am working on machining the tires. I am going with an 0.008" shrink fit. I am trying to hold a plus or minus 0.0005" on the tire ID.

I just received the Frame Crosstie & Bumper Beam Bracket from the foundry. It turned out great. A printed sand mold was use to produce the casting. I am very happy with the results. How to set it up and machine it. Then I can assemble the side frames.

Hi Tim,
This is very interesting! How complicated a process is it to have the foundry create the printed sand mold and make the part?? Is it expensive to create small batches of one off parts, such as 3" scale frame pieces, couplers, etc for a 12" ga loco???
Thanks much
