Back-to-basics Black PLA

4043D PLA Filament

$29.99 USD

No sparkles or fancy finishes here, just premium Natureworks Ingeo 4043D PLA with high quality black 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.

Back To Basics PLA

Recently purchased a spool of Proto Pastas Back to Basics black PLA. Had some parts to print for a piece of shop equipment. This PLA printed beautifully in every way! A good quality material will flow perfectly at PLA settings in my Printrbot Play. No hassles at all. Ran 210C on the Ubis13s hot end, 70C on the build plate. I've purchased Proto Pasta products in the past and I will continue to do so. Thanks you guys, keep up the good work!

At first I was nervous to go to Protopasta because of the price, but in all honesty, it’s really worth it. I’m relatively new to the 3D printing universe, but this is the place to get really good quality filament, and I’m really looking forward to purchasing it’s monthly subscription service
