FLSUN S1PRO

Based on the progressiveness of Delta kinematics technology, it can achieve ultra-high speed printing and accurate printing quality at the same time.

Excellent delta structure:

Three axis parallel structure, high-performance track, high-strength carbon fiber parallel arm, self-developed low center of gravity lightweight tool head, fixed hot bed

Effectively reducing abnormal vibrations during high-speed printing, the movement path of the print head is smoother and more precise, resulting in better printing quality and accuracy


Excellent quality compensation algorithm:

Self developed flow adjustment algorithm, directional optimization vibration compensation algorithm, closed-loop motor control algorithm

More precise flow control, eliminating errors caused by mechanical vibration, effectively improving print quality


Stable and easy to maintain:

The structural characteristics of a delta inherently determine its ultra-high structural strength, stability, and ease of maintenance


Stable body strength:

All metal body frame, high-strength wire rail, high-strength parallel arm, fixed hot bed

Minimize the shaking of the body and the loss of key structural components during use to the greatest extent possible; Reduce maintenance needs


Modular and easy to maintain:

Modularization of effectors, modularization of upper and lower shell components, and modularization of moving parts

Significantly reduce maintenance difficulty

Core points of S1 Pro upgrade

Silent cooling solution

Introducing a new heat dissipation solution that provides greater airflow to ensure print quality while significantly reducing noise, from the original 67dB of S1 to around 55dB (at a distance of one meter from the device, without adding a muffler); High speed printing and quietness are no longer contradictory

Better printing quality

By optimizing the closed-loop motor algorithm, slicing algorithm, and fan cooling, the accuracy, surface smoothness, and detail performance of the printed parts have been improved, enhancing their strength; Significantly improve the overall printing quality

More perfect first layer effect

Dual optimization of hardware and leveling algorithm for better leveling effect, ensuring perfect first layer for every print

FLSUN OS system fully upgraded

The software system has been fully upgraded, with faster response speed and smoother operation

UI improvement and simplification, more intuitive and convenient operation

WiFi connection optimization, increased transmission speed, and more stable connection

V2.0 version slicing software

S1 Pro paired with the all-new FLSUN Slicer V2.0

This version is developed based on ORCA and has been optimized for slicing paths and parameter tuning to better match FLSUN ultra high speed printers. It can ensure that S1 Pro provides excellent printing results while printing at ultra-high speed, meeting users' dual expectations for high speed and high quality.
