FLSUN S1

With a maximum printing speed of 1200 mm/s, an acceleration of 40000 mm/s² and a maximum flow rate of 110 mm³/s, the FLSUN S1 meets all the requirements to enable ultra high-speed 3D printing. The FDM 3D printer has a generous build volume of 320 x 320 x 430 mm and offers powerful components as well as innovative AI functions.

FLSUN S1 vs FLSUN T1 - Key Differences

Focus on ultra high-speed printing

► All-metal frame:

The S1 with its all-metal frame ensures maximum stability even at extremely high speeds.

► High performance:

The S1 is equipped with an extra light dual-gear direct drive extruder. It features a high flow hotend with a 0.4mm hardened steel nozzle rated for temperatures up to 350°C. An 80 W ceramic heating element reaches high temperatures much faster to heat and melt the filament more evenly.

► Powerful cooling fan:

A CPAP turbo fan works at an incredible speed of 40,000 rpm to evenly cool the printed layers. A single layer is cooled within 1 second to achieve smooth printing results!

► 36V closed-loop stepper motor:

Thanks to the closed-loop stepper motor, the S1 can withstand a wide variety of performance needs without any problems. The stepper motor, supplemented with a strain sensor and a control circuit, is incredibly precise and fast, making it perfect for ultra high-speed printing.

► Vibration compensation:

Innovative vibration compensation effectively reduces vibrations that occur at full speed.

AI-Support features:

The following AI-powered features will improve your 3D printing experience:

► AI Lidar Detection: Accuracy Calibration, First Layer Detection, Flow Calibration;

► AI Camera Intelligent Detection with Spaghetti Detection and Debris Detection; with the option of real-time monitoring as well as creating time-lapse photographs.
