FLSUN offers two excellent desktop 3D printer kids, the SR and the QQ-S-PRO. Both printers have remarkable features. However, we are going to compare them based on extruder type, print size, and supported materials. We will base our recommendation on user skill level as well as project needs.
FLSUN SR
The FLSUN SR is a desktop delta 3D printer. It features a Bowden extruder, automatic leveling, and easy assembly.
Printing Speed
The FLSUN SR offers 200 mm/s high-speed printing. It is also equipped with three-axis linkage technology and a 3 x 48 W high-power stepper motor, which support the printer’s normal printing speed. Users will find that they receive instant high-speed printing but still maintain the molding precision quality.
Extruder
The SR features a dual drive Bowden extruder. It minimizes slippage and increases the force by which the filament is fed to match the printing speeds. The printer supports materials such as PLA, PETG, ABS, and flexibles.
Assembly
The printer comes preassembled and full assembly takes approximately ten minutes to complete. It is compatible with Windows, Linux, and Mac OSX. The recommended slicer software is Cura and Repetier-Host. Supported file types include STL, OBJ, and AMF.
Other Specs
The print size is Ø260 x 330 mm. The print volume is 260 x 260 x 330 mm.
With a high precision linear rail guide, the printer provides high printing accuracy, stability, and less noise.
It has a 3.5-inch touchscreen UI. The screen is connected to the printer via a spiral cable and attaches to the printer’s frame with a magnet. The UI is very responsive and easy to work with.
It’s very easy to start printing with the SR due to its automatic leveling feature. Users will find it’s a very quick process to get started. In addition, the printer offers a resume print option. If the power goes out for any reason, the printer will restart the project where it left off, saving time and materials. It also features a removable lattice bed. The bed is a coated lattice glass platform. It offers good filament viscosity and has a replaceable design.
FLSUN offers lifetime technical support following a purchase. Any contact will be responded to within 24 hours.
FLSUN QQ-S-PRO
The QQ-S-PRO is a high-speed Delta 3D printer. It features auto-leveling, a Titan extruder, and an all-metal structure.
Like the SR, the QQ-S-PRO features a print resume function for power loss. Both printers receive the same customer service.
The QQ-S-PRO feature an all-metal structure. It is made from high-quality metal, which provides more stability and gives better printing precision.
The printing size is Ø255 x 360 mm. It features a TFT touchscreen with multiple languages and full color. It is an easy-to-operate and user-friendly UI.
The Titan extruder offers more powerful extrusion. It features smoother feeding and no drawing. If the filament runs out or breaks, the printer will pause until it is replaced. This will save users time and materials.
The printer features an upgraded auto-leveling system. It is easier for users as well as more precise than manual leveling.
The print bed is a lattice platform. It offers excellent adhesion but at the same time, it is easy to remove completed prints.
The printer’s voltage is 110 V – 240 V. Users will need to ensure they have it on the right setting before beginning work.
The nozzle diameter is 0.4 mm. The printer works with 1.75 mm diameter filaments. Accepted filament types include PLA, HIPS, ABS, PVA, wood, and flexible filaments. The heated bed temperature is 0 – 100°C. Print speeds range from 30 – 300 mm/s but average at 80 mm/s.
The QQ-S-PRO works with Windows, Linux, and Mac OSX. It is compatible with slicers such as Cura, Repetier-Host, and Simplify3D. Supported file types include STL, OBJ, and AMF.
The printer features easy setup and is ready to print from the box in just around 20 minutes.
Our Recommendation
While it is clear that both printers offer excellent features, we must delineate between the two before users make a purchasing decision. The FLSUN SR offers extremely fast printing speeds, a dual drive extruder, and automatic leveling. We recommend this printer for beginners and those who have a lot of projects that they need to print quickly.
On the other hand, the SS-Q-PRO offers a Titan extruder, an all-metal structure, and automatic bed leveling. We also recommend this printer for beginners.
