Prusa Releases New Carbon-Fiber and Carbon-Nanotube-Filled 3D Printing Filament

Prusa has introduced its new Prusament PETG ESD filament, which is filled with carbon fiber and carbon nanotubes to create electrostatic-dissipative properties meant to protect static-sensitive electronics. The company is targeting the filament toward electronics production rather than hobbyist use, offering it as a more cost-effective alternative to CNC-machined ESD trays and fixtures. While competitors like 3DXTech and Polymaker already offer ESD filaments, Prusa's version is priced at $56.99, making it cheaper than existing options. It is also reportedly the first to combine carbon fiber reinforcement with carbon nanotubes, which helps improve dimensional accuracy and minimize warping during the printing process.
