Back-to-basics Natural PLA

4043D PLA Filament

$24.99 USD

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. 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.

Great, as always

Great filament at a really good price. I use it most of the time for prints that will bbe painted later. It's a fantastic base with no worries about color coming through.

happy with my purchase

the translucent filament looks great and prints nicely. doesn't smell as deliciously as my hatchbox does but can't complain. and the recyclable spool is a nice touch as well.

Great Filament and Cheap

This filament prints semi-transparent, you'll be able to see your infill or if you just have a thin wall you'll be able to see things that are close through it. It has a slight beige tinge and prints without fuss at 205C hot end/60C bed. I like the environmentally friendly take on this filament, using the cardboard roll (no problems at all with this on my Ender 3) and no pigments.

Unexpected surprise

My first time using proto-plant filament and I used it to print a case for a split keyboard. What's interesting about this filament is it's translucent, so it should pass through RGB quite well. I had to bump up the temperature on my hotend to 215 to prevent it from causing the skipper motor to skip, but after that it was smooth sailing. Really great value and awesome filament. The winds and cardboard reel are much better than I've seen from other vendors.
