The original is still the best! World's First Carbon Fiber PLA filament was kickstarted by ProtoPlant nearly 5 years ago. Others try, but can't match the quality and ease of printing experience afforded by this product. Available at a cost low enough for everyday printing, this Proto-Pasta filament is truly unique.
This is an abrasive filament we suggest you use a hardened nozzle, or reinforced brass nozzle.
