High Performance, Easy Printing...It's World's Best CF!
 
Proto-pasta's High Performance Carbon Fiber HTPLA-CF combines engineering-grade performance with the ease and environmental-friendliness of PLA printing.  Since kickstarting the World's First 3D Printable Carbon Fiber PLA and our original HTPLA, we've wanted to combine the two for a "super-material".  Why is this material "the best"?
Compared to ABS, PET, and similar Polyester materials, HTPLA-CF has:
Easier and more reliable printing
No heated bed required
Lower processing temperatures, like standard PLA
Less warping and distortion when processing
More temperature resistance* for maintaining properties to higher temperatures
Most ABS, PET, and Polyesters get soft at 80C +/- 10C
HTPLA-CF maintains properties up to 120C or more (*when heat treated)
Higher strength and better strength-to-weight ratio for stronger parts with less material 
Improved surface hardness for less wear in abrasive environments
Less shrinkage and distortion for more accurate parts
Higher stiffness so parts hold their shape
Renewable biopolymer with low odor
Highly desirable black finish 
Compared to the Original Carbon Fiber PLA, HTPLA-CF has:
Improved toughness for less breaking when handling and easier processing
Higher HDT when heat treated for maintaining properties to higher temperatures.
Compared to HTPLA, HTPLA-CF has:
Improved surface hardness for less wear in abrasive environments
Less shrinkage and distortion for more accurate parts
 
HTPLA-CF, like Aromatic Coffee, is based on our High Perfomance HTPLA v2.0, so it prints easily and can be heat treated for higher temperature performance with a potential Heat Deflection Temperature (HDT) in excess of 140C (285F) depending on processing. We had good results when heat treating in an oven at 110C (225F) for an hour. We recommend leaving the supports on your parts, placing them on a non-radiating surface (like glass, ceramic, or composite), and letting them cool in the oven to minimize distortion. Parts must be baked above 60C for any crystallization to occur.
Available in 1.75 & 2.85 (3) mm diameter
500g 8" diameter spool only
Carbon Fiber is somewhat abrasive, so consider upgrading to a wear resistant nozzle for less regular maintenance.

In our experience, good results were achieved using standard PLA parameters and standard build surface preparation (blue tape or glue stick). No heated bed required.
