Designer Finish + Engineering Performance for Every Printer!

A bright alternative to Carbon or Glass Fibers, Yellow Matte Fiber HTPLA uses plant fibers great looks in both artistic and technical parts with no special hardware required!


Printed parts have a low luster, textured surface which creates a highly desirable contrast between light and shadow. Texture, color, and sheen can be somewhat manipulated by printer settings as well as post-processing. Printed parts can also be smoothed or weathered with paint for alternate aesthetics. The plant-based fibers lend well to adhesion of paint and other aesthetic coatings.


Based on Proto-pasta HTPLA, this Matte Fiber version can be heat treated to retain more stiffness to higher temperatures. Dimensional stability is improved compared to HTPLA without fibers. The plant-based fibers improve adhesion of glues and coatings. Performance is similar to Carbon Fiber HTPLA but processing of Matte Fiber does NOT require a wear resistant nozzle.


No special hardware or nozzles are required for this plant-based composite. This material is not overly brittle, but is stiff and will break under excessive load. It prints like PLA on non-heated beds. Suggested print temperature is 190-230C, but we had good luck with a slow 1st layer at 230C on cold blue tape and 210C thereafter for a balance of strength and aesthetic.

This material does absorb moisture and dry filament is recommend for best results. When saturated with moisture, this material oozes more readily. Lowering flow and/or temperatures can minimize oozing and improve detail, though higher temperatures are recommended for best mechanical properties. With higher temperatures, ooze artifacts can be removed post build.


This material can be shaved/carved with a sharp blade for a smooth finish. Experiment with weathering or other painting techniques for a unique look. Also, expect improved bonding strength with glue compared to plastic without fiber.

Protopasta Creates Beautiful Prints

I have printed a lot. I mean a lot. I’ve used filament from a lot of companies. The Matte Fiber HTPLA is beautiful. The layer lines are almost unnoticeable, the matte look is gorgeous, the strength (for certain parts, more on this) is better than regular PLA. Depending on how your slicer starts each layer you hardly need to do any finish work. I’m simply amazed. Now back to the strength. The strength for small parts, and I’m talking really small (printed with .25mm nozzle and less than 1mm thick) is not as strong as the non matte filament. So overall, it is amazing and it will be in my filament toolbox for when I need this type of material!


hides layer lines surprisingly well

The matte finish definitely looks great, but what I've found most most notable about it is that it makes the individual layers much less visible than with normal PLA or other more common filaments.

You need this in your life.

The color on all of the matte fiber HTPLAs are super-saturated. This yellow jumps out at you like a school bus. And the surface finish, even with thick layers, is just amazing.

A bunch of Samples...

Overall, I am excited about the products. I purchased a few composites and some matte products to test on my Prusa MK3. Save for the yellow matte material, they have performed well. For some reason, I can't get the matte to stay on the heated bed. I'm within the parameters for the material, but it won't stay put. Using a wide skirt helps, but only marginally. Otherwise, the quality is high and I'll be order more products to test and use for my prints.

I like the matte finish, but...

The matte finish is cool, but the parts are extremely brittle. Also, I was hoping to make a lampshade out of this yellow material but when a light shines through it it looks more orange than yellow.
