Proto Pasta – Matte Fiber PLA (HTPLA)

Proto Pasta – Matte Fiber PLA (HTPLA)

Each Spool is 500g and comes in 1.75mm & 2.85mm


The look of Carbon Fiber without Carbon Fiber. Instead, Black Matte Fiber HTPLA uses plant fibers for a similar texture and sheen.  Great for both artistic and technical parts with no special hardware required!

Designer Finish + Engineering Performance for Every Printer!



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.


Tips & Tricks

In our experience, good results were achieved using standard PLA parameters ranging from 210-230C nozzle with standard build surface preparation (blue tape, glue stick, or BuildTak). No heated bed required but up to 70C okay.  Some shrinkage will occur in the heat treating process, so dimension critical parts may need to be scaled appropriately (as much as 2.5% in our experience).

For this improved the performance, your prints should be baked in an oven until you see a change from translucent to opaque with reduced gloss.  This visual change indicating the improved performance! We've  seen the change take place in 5-10 minutes on thin walled parts but can take an hour or more.  We've had good luck in a quality, at home convection oven at 110C (225F).  Parts will get very "floppy" before becoming more firm, so please leave supports on your parts or support them and bake them on a flat, non-radiating surface (like glass, ceramic, or composite).
