Filament Innovations is a small company based out of Bethlehem PA, run by Michael Gorski.
They currently use Toner Plastics as their extrusion house, and their "Diamond Line" PLA is pure Natureworks Ingeo PLA. Plans are in the works for 5lb and 10lb spools to go with their large format printer and a carbon fiber line as well as a military color line and additional transparents.
I was easily able to get in contact with Michael via the website, and was able to order 50g samples of most of the current color line (Teal was out of stock at the time of ordering.)
As is consistent with Toner Plastic's output, the filament printed easily (minor printing errors in the below swatches are the fault of my abused print bed) The PLA has a nice gloss to it and was easily worked with. Also as is consistent with Toner's line, the neons are not really neon, but brights.
Small note on the photos, using multiple LEDs made the gloss of the PLA come out looking glittery. Better photos pending retakes.
