The 3D printing industry has seen rapid advancements in speed, precision, and user-friendly features. Two standout models in the high-speed desktop 3D printer segment are the FLSUN S1 Pro and Bambu Lab X1C. Both claim to redefine efficiency and quality, but how do they stack up against each other? Let’s dive into their key specifications, performance, and innovations to help you decide which suits your needs best.
1. Speed and Performance
FLSUN S1 Pro boasts a staggering maximum print speed of 1,200 mm/s with an acceleration of 40,000 mm/s² and a flow rate of 110 mm³/s, making it one of the fastest consumer-grade 3D printers available. For example, it prints a standard boat model in 17 minutes, compared to 31 minutes for the X1C. Larger models, like a "Colonel" figurine, take just 1 hour 59 minutes on the S1 Pro versus 3 hours 54 minutes on the X1C1.
Bambu Lab X1C, while slightly slower in raw speed, emphasizes AI-driven precision with features like a laser radar for automated calibration and real-time error detection. Its CoreXY architecture ensures stable high-speed printing, though it prioritizes multi-material and multi-color capabilities over sheer velocity.
Verdict: The S1 Pro dominates in raw speed, while the X1C balances speed with advanced automation.
2. Build Volume and Design
The S1 Pro features a massive build volume of 320 x 430 mm, surpassing competitors like Creality K1 Max (300 mm³) and Bambu Lab X1E (256 mm³). This allows users to print large models without splitting. Its delta structure, full-metal frame, and linear rails enhance stability during high-speed operations.
The X1C offers a more compact 256 x 256 x 256 mm³ build volume, optimized for precision and multi-material workflows. Its enclosed design with aluminum and glass panels ensures temperature control for materials like ABS and nylon.
Verdict: The S1 Pro wins for large-scale projects, while the X1C suits precision and multi-material tasks.
3. Material Compatibility
Both printers support a wide range of filaments, including PLA, PETG, ABS, ASA, and carbon/glass fiber-reinforced composites. However, the S1 Pro stands out with a 350°C all-metal hotend and a heated chamber (up to 50°C), enabling reliable printing of high-temperature materials like PA, PC, and PET17.
The X1C supports similar materials but shines in multi-color printing (up to 16 colors with AMS integration), a feature absent in the S1 Pro14. Its active carbon filter and closed-loop cooling system also enhance safety during prolonged use.
Verdict: The S1 Pro excels in high-temperature materials, while the X1C is ideal for multi-color applications.
4. Software and User Experience
The S1 Pro introduces FLUN WORLD, a cloud platform for remote monitoring, error alerts, and automated bed leveling. Its upgraded FLSUN OS and ORCA-based slicer optimize toolpaths for ultra-fast printing17. Noise reduction to 55 dB (from 67 dB) also improves the user environment.
The X1C leverages Bambu Lab’s AI ecosystem, including a 5-inch touchscreen, neural processing units, and integration with Bambu Studio. Features like spaghetti detection and real-time camera monitoring (1080p) cater to both beginners and professionals.
Verdict: The X1C offers a more polished, AI-driven experience, while the S1 Pro focuses on streamlined cloud control.
5. Price and Value
The S1 Pro is priced at $999 (limited-time offer), positioning it as a cost-effective choice for high-speed, large-format printing.
The X1C retails at $1,499+, reflecting its premium multi-color capabilities and advanced automation.
Verdict: The S1 Pro delivers unmatched speed-to-price ratio, while the X1C justifies its cost with cutting-edge features.
