I was referred to a new (for me, at least) 3D printing web site, 3D Hubs
. They have distributed manufacturing across the USA and can deliver to some places in as little as a few hours.
The upshot is that there are several materials that I haven't seen at Shapeways (my go-to place for the jewelry I design for my girlfriend).
Among the materials available are: Transparent Resins (completely clear, glass-like appearance), Rubber-like Resin (not the same performance as actual rubber, but it's compressible and flexible), Titanium (aerospace quality), Inconel (high strength), and Woodfill PLA (contains wood, bamboo, or cork-based pulverized material, resulting in FDM parts with a unique wood-like appearance).
Personally, I'm wondering about the woodfill PLA. It has an acceptable print volume of 39" on a side. You could print furniture (or at least the parts to assemble furniture).
Oh, yeah... they accept STEP files, so much better for curvy objects than STL.https://www.3dhubs.com/
