The Flsun QQ-S Pro is an all-metal Delta 3D printer kit characterized by high print speed and great accuracy. The device ships mostly pre-assembled in high-quality packaging. The modular design lets you assemble it in 20 minutes or less. The stable metal frame reduces vibration, enhancing print quality even when printing at a high print speed.

The Flsun QQ-S Pro is an upgraded version of the Flsun QQ. Unlike its predecessor, it features a 32-bit motherboard instead of an 8-bit one. The powerful controller makes for stable and durable operation at high speed (up to 300 mm/s). The QQ-S Pro adopts a large glass-ceramic print bed coated with lattice composite. The quality coating allows for quick heating while reducing warping. Also, it enhances the surface adhesion. Once cold, the completed prints can be removed from the bed with ease.

Being a delta-style 3D printer, the Flsun QQ-S Pro bed never moves. This means you only need to calibrate it once. The leveling process is automatic. You’ll only have to push one button and the printer will do the rest. The auto bed leveling relies on a 6+21-point leveling sensor, which allows multi-dimensional leveling of the entire platform. According to the manufacturer, the calibration takes only 3 minutes.

The printer includes a useful resume function that lets you recover a print after a power outage as well as restart it after pausing the device.

The facilitated assembly process along with the auto bed leveling and print recovery features makes it particularly suitable for beginners. If you are a hobbyist or a maker looking for a fast, reliable and accurate 3D printer, the QQ-S Pro is also for you. Read on our review to learn more about its specs.

One user realized a vape stand composed of multiple interlocking parts. The model is made of PETG and has a layer height of 0.1mm. Before assembling the object, the user painted the parts to give the stand a post-atomic look. Here is how it looked before the assembly.

Print quality

The Flsun QQ-S Pro is a desktop delta FDM 3D printer that can print layers at 50 microns. Designed for speed, it is also capable of producing good quality parts with smooth finish fresh off the printer. The automatic calibration mechanism improves the final accuracy, while the smart resuming features reduce the risk of failures.

The Flsun QQ-S Pro comes stock with a 0.4mm nozzle, but it can also hold nozzles of 0.2 and 0.3mm in diameter for finer details.

The QQ-S Pro features a 3-axis linkage motion system aimed to increase the moving speed by 60%. It is engineered with motor cushion, graphite bearing, and quiet dual-fan, which make for quiet operation with a maximum noise level of 50 dB.

The QQ-S is an all-metal delta-type 3D printer with high print speed. It is made out of stainless steel structural components. Since there is minimal vibration of the print bed, the print quality is high.



The Flsun QQ-S Pro prints with PLA, ABS, HIPS, WOOD, PVA, Nylon, and other filaments.

It is engineered with a Bowden-style single Titan extruder that heats up to 270°C. The extrusion unit features a set of twin turbofans for effective cooling when printing with PLA-type materials.

The Flsun QQ-S Pro comes stock with a glass-ceramic heated bed with lattice coating. The bed can heat up to 100°C in less than 5 minutes. This lets you successfully print with the most common consumables.

To ensure high reproducibility, we recommend installing an enclosed print chamber. This way the print quality would not be affected by temperature fluctuations as a result of drafts and other factors.

The Flsun QQ-S Pro prints with generic 1.75 mm filament, giving you plenty of material choices.


Build volume

The build area of 10 x 10 x 14.17 inches (255 x 255 x 360 mm) lets you print small-to-large parts in one go and at a high speed. The final quality is always good, no matter the sizes.

Printer controls

The fitted full-color icon-based touchscreen makes you comfortably operate the printer in standalone mode. Indeed, the QQ-S Pro supports standalone operation via USB or Wi-Fi connection. 

The device adopts a 32-bit Robini mini motherboard with an independent MOS module.

The Flsun QQ-S Pro works with STL, OBJ, G-Code, and other file formats. It is compatible with the free open-source Cura Slicer as well as with the most common slicing software, including Simplify 3D.
