As large-format pellet (FGF) 3D printing continues to expand across industrial applications, printer stability, automation, and logistics efficiency have become key decision factors. This article provides a comprehensive comparison between the Kings FGF1800 and the upgraded FGF1800Pro, highlighting the technical improvements, structural differences, and practical advantages of the Pro version.
1. Build Volume Comparison
- FGF1800: 1800 × 1300 × 1300 mm
- FGF1800Pro: 1800 × 1200 × 1100 mm
While the FGF1800 offers a slightly larger build height, the FGF1800Pro focuses on enhanced structural rigidity and overall system stability, optimized for consistent large-part production.
2. Machine Dimensions
- FGF1800: 2662 × 1950 × 2610.6 mm
- FGF1800Pro: 2650 × 2000 × 2300 mm
Thanks to its optimized design, the FGF1800Pro significantly reduces overall machine height, improving transportation efficiency and installation flexibility.

3. Transmission & Structural Design
- FGF1800: Belt-driven transmission system
- FGF1800Pro: Sealed, dust-proof precision module
The sealed precision module used in the FGF1800Pro greatly enhances component lifespan, minimizes dust contamination, and improves long-term printing stability—especially important for continuous industrial operation.
4. Drive System & Motion Accuracy
- FGF1800: Standard servo motors
- FGF1800Pro: 18-bit high-precision servo motors
The FGF1800Pro achieves mechanical accuracy of up to 0.01 mm, delivering smoother motion control and higher repeatability.
(Note: final part accuracy may vary depending on material properties and shrinkage.)
5. Control System
- FGF1800: Klipper control system.
- FGF1800Pro: Self-developed CNC control system to achieve continuation of printing after the power is off, making it easier to update and have some convenient functions.
The in-house CNC control system enables power-off resume printing, easier system upgrades, and more flexible machine operation, significantly improving production reliability.
6. Printing Head Design
FGF1800: Motor is mounted on top of the printing head, increasing the machine height, so that the printer cannot be packed in a wooden box and must be loaded directly into a 40ft High Cube container.
FGF1800Pro: Inverted motor design reduces the overall height, allowing the printer to be packed in a wooden box and shipped in a 40ft High Cube container.
The redesigned print head allows the FGF1800Pro to be packed in a wooden crate and shipped in a 40ft High Cube container, reducing logistics complexity and shipping costs compared to the original FGF1800, which requires direct container loading.
7. Printing Bed Structure
- FGF1800: Aluminum platform
- FGF1800Pro: Aluminum + composite plastic platform
The upgraded bed structure supports composite base materials and enables ABS and PETG+Glass Fiber printing without heated bed requirements, improving material compatibility and energy efficiency.
8. Dryer & Feeding System
- FGF1800: Dryer for pellet drying only
- FGF1800Pro: Integrated dryer with automatic pellet feeding
The FGF1800Pro’s automatic feeding system supports connection with both small and large dryers, enabling uninterrupted, large-scale production.
9. Packing & Shipping Data
- FGF1800:
Packing size: 285 × 210 × 280 cm
Gross weight: 1745 kg
- FGF1800Pro:
Packing size: 298 × 223 × 253 cm
Gross weight: 1674 kg
Despite enhanced features, the FGF1800Pro achieves a more compact shipping profile and reduced overall logistics burden.
Conclusion: Why Choose FGF1800Pro?
The Kings FGF1800Pro represents a comprehensive upgrade over the standard FGF1800, featuring:
- Sealed precision transmission system
- High-precision 18-bit servo motors
- Self-developed CNC control system with power-off resume
- Automatic pellet feeding
- Improved printing bed structure
- Optimized machine height for crated shipping
These enhancements deliver higher reliability, longer component lifespan, easier operation, and more efficient logistics, making the FGF1800Pro the preferred large-format pellet 3D printer for industrial users seeking stable, scalable, and cost-effective production.
