Highlights
Ultra-high Printing Speed Saves Time
1200mm/s maximum speed and 40,000mm/s² acceleration, the printing speed is several times higher than that of ordinary 3D printers, the ultra-stable delta structure reduces printing vibration, and the printing accuracy and model details are very high.
Monitoring and Control
For the first time, more precise control and monitoring modules have been added, using advanced Microtac radar control and a WIFI real-time connection. With the visual operation interface, smart adjustment and monitoring can be realized on mobile phones and PCs to ensure printing quality and accuracy.
Simple Operation
The device self-checks to maintain the stability of the printer, and automatic leveling makes operation easier. The whole machine can be used within 10 minutes after delivery. It has a low printing noise of 55dB, a simple and easy-to-use operation interface, and the machine supports power-off continuous printing and vibration compensation to ensure smooth printing and quality.
High Applicability
The all-metal hot end can reach up to 350°C, and with the latest built-in temperature control pad, the temperature is always stable. The ultra-high temperature multi-metal integrated throat nozzle is suitable for ABS, ASA, PC, PA, PETG, PLA and other consumables. It also supports high-performance consumables such as PPS-CF, PPA-CF/GF and a variety of nozzle sizes.

FLSUN Algorithms 2.0
Advanced algorithms enhance filament detection and auto bed leveling, reducing print failures and ensuring a perfectly leveled first layer. Proprietary flow calibration and pressure advance algorithms enable precise extrusion, improving print quality and accuracy.
Uncompromising Quiter Fan
Operating at 55dB, the new cooling system delivers powerful performance to support high-speed printing, minimizing noise for a distraction-free environment.
Power Off Resume Print
Equipped with a UPS power supply, the S1 Pro ensures accurate recording of each movement. In case of power interruptions, the effector is zeroed to prevent the hotend from damaging the model, avoiding print defects.
Engineered for High Reliability
The FLSUN S1 Pro delivers expert-grade performance with a robust mechanical structure and high-quality components. Its modular design enhances maintainability by modularizing the effector, housing components, and moving parts, simplifying maintenance.
