Prusament PEI 1010 is our self - made 3D printing filament. Josef Prusa was not happy with market filament quality, so we made our own. We're the only 3D printer maker with in - house filament production. Every step of manufacturing is closely monitored and tested. Check every spool's parameters at prusament.com. This filament is great for aerospace, automotive, and industrial parts due to its high durability and stability under thermal stress. It's made of premium materials and guarantees ± 0.05 mm precision, with high - temperature and chemical resistance. Scan the QR code on the spool to view all details online. Note: It's not for Prusa MK, XL, and MINI series printers as they can't reach the required printing temperature. Check your printer's capabilities. PEI 1010 is a highly resistant polymer, flame - retardant, and resistant to gamma radiation. It can replace aluminum alloys in industrial use. But it needs a Prusa Pro HT90 or a printer with a heated chamber (min 90 °C) for printing. Also, it absorbs moisture easily, so dry it before each print and store it in a dry box during printing. Printing settings: Nozzle 410±10 °C, Heatbed 150±10 °C, Chamber temp 90 °C +, Recommended print sheet: Textured / PA Nylon, PrusaPro HT90 Printhead: High Temperature. Pros include exceptional mechanical properties, high strength - to - weight ratio, etc. Cons are high working temperatures, moisture absorption, strong adhesion to PEI surface, and large prints may warp.
Using Prusament PEI 1010 filament is a great way to create high - performance 3D printed parts. First, make sure your printer can handle the high temperatures. It's not suitable for Prusa MK, XL, and MINI series printers. For other printers, set the nozzle to 410±10 °C, the heatbed to 150±10 °C, and keep the chamber temperature at 90 °C or higher. Use a textured or PA Nylon print sheet. The PrusaPro HT90 printhead should be set to high - temperature mode. Before you start printing, dry the filament as it easily absorbs moisture. You can use a dry box to keep it dry during the printing process. After printing, be careful when removing the part as it has strong adhesion to the PEI surface. You may need a separation layer. If you're doing large prints, be aware that they might warp. Store the filament in a dry place to maintain its quality. Also, you can check the parameters of each spool by scanning the QR code on it.
