I printed a "school" of Piranhaz for my nieces using Polyalchemy Elixir filament. The filament has a gorgeous shine to it.
I've used Elixir on a lot of prints and it's shine is unmatched by any other filament I've tried. It didn't bridge well on this print though. If you watch it extrude from a raised hot end, it doesn't just drop to the build plate and lay there like other filaments. It will contract back into itself not unlike a snail going back into it's shell. This is irregardless of temperature. Strange stuff. I suspect this is why it didn't bridge as well as other filaments I've used.
