The S1 Pro is built for speed, reaching up to 1200 mm/s with a peak flow rate of 110 mm/s. Its high acceleration of 40,000 mm/s reduces print times significantly, making it ideal for large-scale projects and rapid prototyping.
Large Build Volume
With a print area of 320mm x 430mm, the S1 Pro can handle sizable prints, making it suitable for engineering parts, functional prototypes, and creative projects that require more space.
Advanced Material Compatibility
Beyond standard filaments like PLA and PETG, the S1 Pro supports high-performance materials such as PPS-CF/GF and PPA-CF/GF. This allows for the creation of parts with high mechanical strength and chemical resistance.
AI-Powered Precision
Equipped with FLSUN Algorithms 2.0, the printer features auto bed leveling, spaghetti detection, filament clog detection, and advanced extrusion calibration. These enhancements improve print quality and reduce the risk of failed prints.
Quiet and Efficient Operation
Operating at just 55 dB, the S1 Pro runs quietly without compromising performance. It also features intelligent zoned heating for energy-efficient temperature control.
Practical and Reliable
The printer includes a HEPA and activated carbon filter for improved air quality, a built-in filament dryer, and power loss recovery to prevent print failures. With a 95% pre-assembled design, setup is quick and straightforward.
Designed for both professionals and hobbyists, the FLSUN S1 Pro combines speed, reliability, and intelligent features to enhance your 3D printing experience.
