Our most popular exotic material, Proto-pasta Carbon Fiber Composite HTPLA is a combination of milled carbon fibers and high-performance PLA. Resulting 3D prints made with our Carbon Fiber HTPLA are demonstrably more rigid, providing excellent structural strength and layer adhesion with very low warpage. The embedded carbon provides a beautiful light matte gray finish with a slight sheen, resulting in 3D prints with exceptional accuracy, finish, and performance!
What is HTPLA and how does it work?
Protopasta HTPLA is PLA that can be heat treated for higher temperature resistance compared to standard PLA. Heat treating changes the material structure from amorphous to crystalline. While amorphous structures change drastically near their glass transition temperature (Tg), crystalline structures maintain useful properties above Tg and towards melting (Tm). Thus, heat treating greatly increases the useful range as seen by the difference between Tg and Tm in the DSC results below.
