Faster than ever!

The Flsun S1 is currently at the forefront of fast 3D printers available on the market thanks to its impressive top speed of 1200 mm/s and acceleration of up to 40000 mm/s² . These parameters guarantee exceptional speed of work, enabling projects to be completed in a much shorter time. The manufacturer has designed the printer so that even such high speeds do not negatively affect the quality of the final print.

Filaments ready for work

The device is distinguished by a built-in filament dryer, which allows proper preparation of the filament for the printing process. It allows the fiber to be maintained in optimal conditions , eliminating moisture problems, which is especially important when working with hygroscopic materials. It is also a convenient solution for storing filament.

Lidar sensor

Equipped with an intelligent Lidar sensor, the S1 printer is able to detect problems with the first layer of printing, as well as optimize printing precision and the level of filament flow. In addition, Lidar is used in the automatic leveling system of the work table.

AI camera

The integrated AI camera allows you to remotely track printing progress in real time , as well as create time-lapse photos and videos. Additionally, this camera detects printing problems and informs the user if any errors occur during printing.


The printer has an intelligent camera.


Efficient cooling and precise stepper motors allow the printer to operate at high speeds.

High-performance fan

The printer uses an advanced system with a powerful fan operating at an impressive speed of 40,000 rpm to effectively cool prints. It is able to cool one layer in a second , so even when the printer is working quickly, it provides excellent results.

Powerful stepper motors

Stepper motors in a 3D printer are crucial for precise and stable printing. Their task is to ensure accurate positioning of the print head, which is the foundation for high-quality prints. Closed-loop stepper motors that S1 has are distinguished by extraordinary efficiency and allow it to achieve the highest precision .
