Back-to-basics White PLA

4043D PLA Filament

$3.00 USD $4.00 USD


No sparkles or fancy finishes here, just premium Natureworks Ingeo 4043D PLA with high quality white pigment. Master-batched and extruded in house to be your go-to basic PLA filament for a premium experience. Spooled onto cardboard spools to minimize environmental impact and maximize value. 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! Protopasta 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.

Punches far above its weight

I'm thoroughly impressed with this filament. Layer adhesion and "fusion" is excellent. No stringing, no fuzziness, and precise. Produces prints at par with more costly, pro-grade filament. All four prints in the attached imaged were done using Protopasta BTB PLA.
