FLSUN S1 Pro - Ultra-fast Delta 3D Printer

Designed for enthusiasts and demanding professionals, the FLSUN S1 Pro redefines the standards of Delta 3D printers. It combines exceptional print speed with a large cylindrical volume, while offering broad compatibility with technical materials.

Thanks to its enclosed chamber, high-temperature components, and numerous smart features, it meets the highest demands of rapid prototyping and production.

This FLSUN printer is optimized to reduce noise levels during operation, limited to just 55 dB.

Features of the FLSUN S1 Pro

With its advanced Delta structure, the FLSUN S1 Pro focuses on pure performance. Speed, precision, print volume, and material compatibility: everything is designed to deliver a premium 3D printing experience.

Extreme Print Speed

The FLSUN S1 Pro reaches printing speeds of up to 1200 mm/s, with acceleration rates of up to 40,000 mm/s².

With its ultra-rigid Delta design and optimized motion control algorithms, it prints complex parts in record time without compromising detail quality.

Large printing volume

With a cylindrical volume of Ø320 × 430 mm, the FLSUN S1 Pro offers ample space for manufacturing large parts or multiple objects in a single print.

Its vertical structure allows for a reduced footprint despite the impressive print height.

Compatibility with technical materials

Equipped with a hotend featuring a hardened steel nozzle reaching 350 °C, a heated bed up to 120 °C, and an enclosed chamber maintaining 50 °C, the FLSUN S1 Pro is ideal for printing advanced materials such as nylon, PETG CF, PC, or TPU.

It thus meets the demands of professional users.

Innovations and performance with the FLSUN S1 Pro

The FLSUN S1 Pro is not just fast and powerful. It also integrates numerous smart features that enhance user experience, safety, and the reliability of every print.

Built-in artificial intelligence

The S1 Pro uses artificial intelligence to monitor filament status in real time, detect print defects (clogs, spaghetti), automatically calibrate the bed, and optimize extrusion quality.

These algorithms ensure reliable prints, even over long print durations.

Quiet operation

Thanks to a new optimized cooling system and quiet motors, the FLSUN S1 Pro operates at only 55 dB.

It is thus perfectly suited for shared work environments or home use, without noise disturbances.

Air filtration system

To ensure healthier air even when printing technical materials, the S1 Pro is equipped with a HEPA filter combined with an activated carbon filter.

This system captures fine particles and reduces odors, while maintaining a clean and safe printing environment.

FLSUN S1 Pro filament storage and active drying

Filament storage with drying

An integrated compartment allows to store and dry filament during printing.

Thanks to gentle and controlled heat, moisture is efficiently removed, ensuring consistent extrusion, ideal for sensitive materials like nylon or PETG.

Intelligent heated bed

The FLSUN S1 Pro automatically adjusts the bed heating to the size of the printed part.

This smart zoned heating feature saves energy and reduces heat-up time while ensuring optimal adhesion.

Our opinion on the FLSUN S1 Pro

The FLSUN S1 Pro is one of the most impressive Delta 3D printers on the market. Its maximum speed of 1200 mm/s in production significantly saves time without sacrificing quality. The generous volume of Ø320 × 430 mm is ideal for functional parts or large-format prototypes.

We especially appreciated the compatibility with demanding materials like reinforced nylon, thanks to the 350 °C hotend, 120 °C bed, and 50 °C enclosure. For comfort, the integrated AI (automatic calibration, defect detection, monitored extrusion) is a real plus for reliable prints.

The active filament drying and filtration system further reinforce its professional positioning. A machine we recommend without hesitation for advanced users or small series production.
