Since I have only seen nylon with glass fibers in black or natural from all the filament suppliers, I was pleasantly surprised that one of my suppliers now has nylon GF in various colors. I ordered samples in orange, red and gray. I printed with the same settings as Nylon Carbon. I'm really excited, it prints well and has the same pleasant surface as nylon carbon, the color comes out beautifully, looks a bit matt, not shiny. I think it's a great thing if you need stable parts but don't like black.
