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! 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.
