I had an N scale concrete bridge section printed out in Shapeways' new Gray Fine Detail Plastic to test it out. Overall, I like it better than the regular fine detail plastic. It still has layer lines, but they are fine and sandable. And there is a tiny bit of leftover support wax in some crevices that will make me give it a Bestine soak before painting. The pricing is similar to regular fine detail plastic, but depending on how much wax support a given print requires will determine if it costs more or less than regular. (Update August 2023, the gray has been replaced with a tan color. I liked the gray color better but tan is fine.)
