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.

Protoplant PLA filament

good results so far with several different colors

it just works

The parts I've printed look molded. At 0.16 layer height the layers are hard to distinguish. I'm printing with a nozzle temp of 200 C with bed temp of 60 C on an Ender 3 Pro. I've had some adhesion issues with thin parts, but otherwise I've been pleased.

Great stuff- I like the environmental benefits too!

Easy to print on Prusa i3Mk3S+, looks good. I purchased this because ProtoPasta is in Washington, and because of the cardboard spool.

Great filament, great company

The basics black works great in my small hobby printer. Wish the color could be a little more on the matte side, but that is a limitation on the type of plastic. The only issue I have is that the cardboard spool grabs every so slightly on my spool holder and underextruded a little bit. A better drive motor or a direct drive (my machine has a cheap Bowden) will be un-noticeable.

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!
