• Back-to-basics Natural PLA - No sparkles or fancy finishes here, just natural, unmodified Natureworks Ingeo 4043D PLA resin extruded into filament and spooled onto cardboard spools to minimize environmental impact and maximize value.
• Finishing Variety - With the option to heat-treat, wire brush, or polish this filament 1.75 gives you plenty of different choices to give your finished product a different look.
• Environment - Friendly Material Spools - Many filaments are wound onto wasteful plastic spools because it's cheap and easy, but cardboard is sturdy enough for single use, saves shipping weight, and is easily recycled when done! Proto-pasta filament is first dried, then extruded without moisture using air cooling for exceptional quality. Minimal waste, no water use, and no additives because less is more when meeting basic needs.
• High Quality - Proto-pasta offers only U.S-made, high-quality 3D printer filament PLA. Using only premium materials with a focus on craftsmanship this PLA 1.75 is one you can trust to get the job done.
• Easier to Use - This PLA Filament 1.75 mm has been flow-optimized and has less moisture than standard PLAs to help avoid heat soak and to keep mass flow up. This combination of features makes it easier to use than most standard PLAs.
