Matte Fiber can create beautiful, rigid parts that don’t even look 3D printed. Like wood, Matte Fiber does not bend much before breaking. Please don’t use excessive force when loading and printing. Matte Fiber also absorbs moisture like wood, and should be printed at the lowest possible temperature to minimize stringing, over-extrusion, and jamming.

So cool!

I was shocked to feel this filament and it felt rough like wood would be without sanding it. Printed a decorative pumpkin out on this filament and it turned out fantastic.

Great and easy to print

The product printed easily through my Anet A8. Definitely follow the temperature that Protoplant recommends. I had slight oozing which usually happens on machine from the material being a bit hot. The part it printed looked great and I'm about to buy a whole 500g roll instead of the 50g coil I got for one little print.

Both matte and iridescent

This filament is terrific, and with short layer heights the lines are nearly imperceptible. I ran this through a Prusa Mk3S+ at 205/60 and had absolutely no problems with an 18 hour print. I printed it twice and it was flawless both times, no special settings or hardened nozzles. There's notable stringing, more so than with other "traditional" Proto-Pasta filaments. The texture and appearance has both a nice matte fiber finish and a tiny bit of iridescence or pearlescence; it definitely has a shimmer when bright light hits just right. Overall, it's a really nice filament and serves well if you're looking for a woody aesthetic.
