FLSUN S1: The Ultimate Review for the High-Speed 3D Printer
Introduction
The FLSUN S1 is a 3D printer specifically designed for users who require the highest speed and precision in their print projects. With impressive technical specifications, such as a maximum print speed of 1200 mm/s and acceleration of up to 40,000 mm/s², the FLSUN S1 sets new standards in 3D printing technology. In this comprehensive review, we take a detailed look at the features, build quality, and performance of this remarkable printer.
Technical highlights of the FLSUN S1
1200 mm/s maximum speed and 40,000 mm/s² acceleration
The FLSUN S1 is not an ordinary 3D printer. With a maximum print speed of 1200 mm/s and an impressive acceleration of 40,000 mm/s², it outperforms most competitors on the market. These speeds are possible thanks to the closed-loop control system that monitors and corrects the movements of the stepper motors in real time. This leads to a drastic reduction in print times without compromising print quality.
Large build volume of 320 x 320 x 430 mm
The generous build volume of 320 x 320 x 430 mm allows for printing large projects in one go. Whether prototypes, model parts, or larger components – the FLSUN S1 offers ample space and flexibility for a wide range of applications. The stable construction and precise calibration of the printer help ensure that there are no quality losses even with large prints.
Microtac Radar for precision control
One of the outstanding innovations of the FLSUN S1 is the Microtac Radar system, which monitors and improves print quality and accuracy. This system monitors the first layer as well as the entire printing process and makes automatic adjustments as needed to ensure consistently high print quality. This is especially useful for complex projects that require the highest precision.
All-metal hotend up to 350°C
The all-metal hotend of the FLSUN S1 can reach temperatures up to 350°C, enabling the use of a wide range of filaments, including high-strength and heat-resistant materials. The high temperature tolerance ensures that the printer delivers excellent print quality even with demanding materials such as nylon, polycarbonate, and carbon fiber filaments.
Build quality and technical details
Construction and stability
The FLSUN S1 is robustly built and weighs a total of 39 kg. The massive dimensions of 550 mm x 595 mm x 1030 mm provide a stable base that minimizes vibrations and ensures consistent print quality. The metal frame construction and precise workmanship contribute to the printer's durability and reliability.
Print bed and print chamber
The print bed of the FLSUN S1 consists of a PEI surface that ensures optimal adhesion of the first layer. It can be heated up to a maximum temperature of 120°C, which facilitates printing of ABS and other demanding materials. The printer offers the flexibility to operate either in an open or closed print chamber to meet different printing requirements.
Filament and extruder system
The FLSUN S1 uses a dual-gear direct drive extruder system that ensures reliable filament feeding. The printer supports filaments with a diameter of 1.75 mm and is equipped with an open filament system that allows the use of third-party filaments. This gives users more flexibility in material selection.
User-friendliness and safety features
Touchscreen and user interface
The FLSUN S1 is equipped with an intuitive touchscreen that allows for easy operation and control. The user interface is clearly designed and provides quick access to all important functions and settings.
Automatic self-diagnosis and error detection
The printer features a self-diagnosis system that performs a check of the main components before each print job. This minimizes the risk of print errors and contributes to the device's longevity. Additionally, sensors for filament roundness, filament clogging, and power failure are integrated, which monitor the printing process and take immediate action in case of problems.
Connections and connectivity
The FLSUN S1 offers several connection options, including USB and camera. The camera allows real-time monitoring of the printing process, which is especially useful for remote monitoring. Thanks to the USB port, print files can be loaded directly from the USB stick, which further simplifies operation.
Precision and resolution
With a layer height of 0.1 to 0.35 mm and a resolution of 0.1 mm, the FLSUN S1 delivers extremely precise print results. The high accuracy makes it ideal for detailed projects where every detail counts.
Shipping and scope of delivery
The FLSUN S1 is delivered in a sturdy package measuring 620 mm x 660 mm x 1100 mm and weighing a total of 46 kg. This ensures that the printer arrives safely and undamaged to the customer.
