Large-Format Single-Pass Printing
The BIG-120X V4 is purpose-built for 3D printing large models in a single pass, eliminating the need to split designs into smaller sections and glue them together. This dramatically reduces post-processing time and produces stronger, cleaner results with no seams or alignment issues.
- 3D print oversized parts as one complete, seamless piece.
- Reduce post-processing and assembly labor significantly.
- Ideal for prototypes, props, fixtures, and large functional parts.
Built Into the BIG-120X
Electronic ControllerThe Duet 2 WiFi controller powers professional 3D printers with a high-performance 32-bit processor and quiet TMC2660 stepper drivers. It offers flexible connectivity, dual extruders, and external SD card support for a seamless printing experience. Key features include:
|
Griffin Print Head AdvancementsThe Griffin Print Head is the new standard across the printer lineup, featuring a custom Bondtech extruder and an innovative Modix hotend. Key features include:
Note: Use a high-temperature nozzle for temperatures above 300°C. |
Automatic Filament ChangerThe IDEX system serves as an automatic filament changer, allowing for seamless print workflows by switching between print heads when filament run-out is detected. This enhances efficiency by automatically swapping spools, reducing manual intervention during long jobs. Additionally, it maintains chamber temperature, preventing defects in partially printed models. |
Tilt Screen, Emergency Button & Frontal Power SwitchThis feature set is standard on BIG-Meter and BIG-120Z models, with optional availability for other printers:
|
Motion SystemExperience precision motion with HIWIN linear guide rails, Z-axis ball screws, reinforced belts, and NEMA motors, achieving travel speeds up to 350mm/sec. Key features include:
Mechanical position accuracy:
Print speeds (0.4mm nozzle):
|
Power and ElectronicsSupport for both 110V and 230V power supplies ensures compatibility. The Mean Well 24V 280W power supply includes protections against short-circuit, overload, over-voltage, and overheating, with a no-load consumption under 0.5W and an LED indicator. Key components include:
|
SoftwareUtilize the open-source Duet RepRap firmware and choose from popular slicers and 3D-printer controllers. Modix printers are compatible with:
Specific printer configurations are supplied in the customer zone. |
Clog DetectorPreviously an optional add-on and now standard with every printer, the clog detector improves printer reliability. Its custom high-sensitivity encoder detects:
The detector is a drop-in replacement for the existing filament run-out sensor. Two units are recommended for a dual-print-head configuration. |
Modular Design Built for Upgrades
The BIG-120X V4 features a modular architecture that makes it easy to swap components, add new capabilities, and keep pace with evolving 3D printing technology. Whether you want to add a second extruder, upgrade the hotend, or integrate new sensors, the platform is designed to accommodate future improvements without starting over.
- Swap or upgrade individual modules without replacing the entire 3D printer.
- Supports a wide range of community and manufacturer-developed upgrades.
- Protects your investment as printing technology and your needs advance.
Available Add-Ons
 Chassis & EnclosureThe chassis is made from solid 40x40 T-slot aluminum profiles with powder-coated laser-cut aluminum brackets and joints. An optional 3mm black Aluminum Composite Panel (ACP) enclosure is available for the BIG-60, BIG-120X, and BIG-120Z models, while it comes standard for the BIG-Meter and BIG-180X. |
 Super High Flow HotendOpt for the Super Volcano hotend for high-speed printing of large, robust objects, especially those requiring structural integrity like thick vase-mode styles. This upgrade, based on the E3D Super Volcano heat block and nozzles, features an 80W heater and thermistor, along with a CNC-made mounting bracket for stability and protection. This setup enhances efficiency, reduces vibrations, and improves print quality. Includes:
|
 IDEX Dual PrintingThe Modix printer features Independent Dual Extruder (IDEX) technology, allowing for intricate models with internal geometries and dense support layers, reducing post-processing and improving success rates for complex prints. IDEX is an optional add-on for Generation 4 printers, but included in this professional bundle, which consists of:
|
 Active Air FilterThe Modix Active Air Filter (MAAF) purifies the printer's chamber by capturing micro-particles and fumes during 3D printing. It features a multi-layer filtering system with a pre-filter, HEPA filter, and active carbon filter. Installing the MAAF is vital for health, especially when printing with materials like PETG and ABS, as harmful particles can be released. Users can control airflow speed to optimize filtration and cleaning. Replacement filters are needed every 3 to 12 months, with alerts on the front panel for timely changes. |
 Print Surface and Removable Magnetic BedThe Alcoa Mic6 milled cast aluminum plate provides a consistent print surface, complemented by an optional removable magnetic bed add-on for easy print removal. Modix printers feature a default PEI sheet that releases prints upon cooling, but the magnetic add-on allows for instant removal by bending the spring steel plate. This add-on includes an adhesive magnetic sheet for the aluminum bed and a dual-sided spring steel plate: one side is textured with PEI, the other is smooth and glossy. Key specifications include:
