Designer Finish + Engineering Performance for Every Printer!

A bright alternative to Carbon or Glass Fibers, Red 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.

Excellent, love all of your filamentments I have tried. Great also to have speciality filament. Keep up the great work.....pity I also have to pay UK customs or I would buy more .....but worth it

Matt Fiber

The matt fiber has a very nice hand feel and works well to hide layer lines. However I found it is best used for organic pieces that have limited chances to string. Continuous perimetets work great but if you have multiple perimeters in a later the matt fiber material loves to string hair fibers everywhere.
