  "account": "Prusa has introduced a new 3D printing filament called Prusament PETG ESD, which is made with carbon-fiber and carbon-nanotube (CNT) fillings. This ESD (electrostatic-dissipative) filament is designed to protect static-sensitive electronics such as Raspberry Pis, ESP32s, and similar devices. The company aims this filament more towards electronics manufacturing rather than hobbyist use, but it is priced more affordably at $56.99 for a 1kg spool compared to Prusa's non-ESD PETG Carbon Fiber filament which costs $56.99.\n\nPrusa is not the only company offering ESD filaments; 3DXTech and Polymaker have been in the market before, but Prusa is the first to combine carbon fiber with carbon nanotubes to enhance ESD properties. Alongside these benefits, Prusament PETG ESD provides improved dimensional accuracy and minimizes warping.\n\nWhile many other filaments are considered safe for electronics enclosures, such as PLA, PETG, and ABS, Prusa positions this new filament as more suitable for production use rather than hobbyist projects. It can replace costly CNC-machined ESD trays and fixtures, and can be printed on-site with minimal lead time. This not only reduces manufacturing costs but also enables a quicker production process, benefiting both larger businesses and smaller-scale manufacturers.\n\nAlthough Prusa has not released a detailed datasheet about the filament's strength, they claim that it offers increased stiffness and reduced toughness, similar to their Prusament PETG Carbon Fiber filament. However, they note that the amount of carbon fiber in PETG ESD might differ from PETG Carbon Fiber, as the latter is primarily designed for strength rather than electronics manufacturing. Prusa utilizes its own 3D printers for its production needs, including printing its own components using the Prusament PETG ESD filament. This filament is not the first or only ESD option on the market, but it is currently the most budget-friendly choice. When its strength profile is independently tested or released, it may prove to be a more cost-effective alternative to Prusa's own PETG Carbon Fiber filament in specific scenarios.",
  "summary": "Prusament PETG ESD is the cheapest ESD filament on the market, while being carbon-fiber reinforced, something the competition doesn't have.",
