High speed printing up to 600 mm/s on Ender-3 V3 printers with bimetal heat management to prevent thermal creep, keeping prints accurate at speed. Fast warm-up with a 60 W ceramic heater, delivering efficient heat transfer and reaching 300 C in about 40 seconds for quick readiness. Built for high temperature durability with all-metal components that withstand up to 300 C for stable, repeatable performance. High melt efficiency: the hottest section operates at 30% efficiency to ensure complete filament melting even when printing rapidly at 600 mm/s. Use scenarios - Rapid prototyping and functional parts on Ender-3 V3, reducing wait times for design iterations. - Printing high-temperature materials up to 300 C, such as ABS, PETG, or PC, with reliable performance. - Large or high-detail prints that benefit from consistent extrusion and reduced thermal creep at high speeds.
