Matte Fiber HTPLA - Gray

Regular price $239.95 USD

Designer Finish + Engineering Performance for Every Printer!

A neutral gray reminiscent of concrete or stone.  Gray Matte Fiber HTPLA feels industrial, but uses plant fibers for texture and sheen.  Great for 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.

Great PLA

Love all the Proto Pasta I have tried. The matte fiber finishes are great for everyday prints. They don’t have that shiny plastic look like normal PLA. This is my new favorite stuff to print with.

Frickin’ Awesome

I normally only use the Ultimaker filament. A good friend suggested ProtoPlant to me and I loved the results.

Easy to use, amazing results.

Very easy to print with and the resulting print looked exactly as I thought it would. The fibers and matte finish help to hide the layer lines. Will be buying again!

Prints great, looks better

Love this filament for certain prints, has a unique feel and texture with consistent prints. Layer lines virtually disappear with the texture as well. People not familiar with printers have had no clue how I was able to create the objects.

Really Nice Filament

This filament works very well on my QIDI Tech printer. I use a glass build plate at 60 degrees, and print at 200-205 degrees. I really like the textured finish, and the matte surface appearance provides great contrast on the completed print. I'll be back for more matte fiber filament in other colors, and will be picking up some iridescent ice and some silver-smoke translucent as well (I tried these previously as sample packs).
