Taulman Bridge 3D Printer Filament Review
I just received some Taulman Bridge Nylon 3D printer filament from extrudables.us this weekend and I’ve been printing just a few parts on it so far. Since I only have 1 pound of the material I am saving it for when I really need it, as opposed to PLA or ABS where I feel like I […]
