2. Key Features
The Snapmaker 2.0 Dual Extrusion 3D Printing Module enhances your 3D printing capabilities with several advanced features:
- Multi-Material Printing: Combine different materials in a single print, such as PLA and TPU, for functional parts with varied properties.
- Multi-Color Printing: Produce prints with two distinct colors, adding visual complexity and detail to your models.
- Dissolvable Support Printing: Utilize dissolvable support materials like PVA for complex geometries and hollow structures, resulting in smooth surfaces and high dimensional accuracy.
- Breakaway Support Printing: Employ breakaway filament for supports that are easy to remove without extensive post-processing.
- Quick-Swap Hot Ends: Hot ends can be easily removed and replaced in approximately 5 seconds, facilitating material changes and maintenance. The Luban software automatically recognizes the installed hot end and suggests appropriate printing parameters.
- High-Performance Extruder Gear System: Features a 7.5:1 planetary gear system combined with dual extrusion gears for reliable and precise filament feeding.
- Optimized Cooling System: Incorporates a 4-fan cooling system to ensure consistent temperature control and improved print quality, especially during dual extrusion.
- Various Nozzle Sizes: Supports different nozzle sizes (e.g., 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm) for optimizing print speed and detail, allowing for fine details or faster infill.

4. Setup and Installation
This section outlines the general steps for installing the Dual Extrusion 3D Printing Module onto your compatible Snapmaker 2.0 machine. Refer to your Snapmaker 2.0 main unit manual for specific instructions on module replacement.
- Unpack the Module: Carefully remove the Dual Extrusion 3D Printing Module and all accessories from its packaging. Verify that all components listed in the packing list (refer to Image 4.1) are present.
- Prepare the Snapmaker 2.0: Ensure your Snapmaker 2.0 machine is powered off and disconnected from the power source. Remove any currently installed 3D printing module or tool head.
- Install the Dual Extrusion Module: Align the Dual Extrusion 3D Printing Module with the mounting points on the Snapmaker 2.0 linear module. Secure it in place using the provided screws or locking mechanism.
- Connect Filament Tubes: Attach the filament guide tubes to the module and route them to your filament spools.
- Load Filament: Insert the desired filaments into the respective hot ends (left and right). Follow the on-screen prompts on your Snapmaker 2.0 touchscreen for filament loading.
- Power On and Calibrate: Reconnect power to your Snapmaker 2.0 and power it on. The machine will detect the new module. Proceed with the calibration process as guided by the Luban software or the machine's touchscreen interface. This typically includes bed leveling and nozzle offset calibration for dual extrusion (refer to Image 4.2).

5. Operating Instructions
Operating the Dual Extrusion 3D Printing Module involves preparing your 3D models and managing printing parameters within the Snapmaker Luban software.
5.1 Preparing Models for Dual Extrusion
- Software: Use Snapmaker Luban software to prepare your 3D models. Luban provides specific settings for dual extrusion printing.
- Assigning Extruders: Within Luban, you can assign different parts of your model or support structures to specific extruders (left or right). This allows for multi-color or multi-material prints.
- Material Profiles: Select appropriate material profiles for each filament used. Luban will automatically adjust printing parameters based on the recognized hot end and material.
5.2 Printing Process
- Slice Your Model: After assigning materials and settings, slice your 3D model in Luban. This generates the G-code for the printer.
- Transfer G-code: Transfer the generated G-code file to your Snapmaker 2.0 machine via Wi-Fi, USB, or other supported methods.
- Start Printing: On the Snapmaker 2.0 touchscreen, select the G-code file and initiate the print. The machine will perform any necessary pre-print checks and begin the dual extrusion process.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your Dual Extrusion 3D Printing Module.
- Hot End Cleaning: Periodically clean the nozzles and hot ends. Use the provided wire brush to remove any filament residue. For stubborn clogs, refer to the Snapmaker support documentation for hot end disassembly and cleaning procedures.
- Filament Path Inspection: Check the filament guide tubes and the path within the module for any obstructions or wear. Ensure smooth filament feeding.
- Module Cleaning: Keep the exterior of the module clean and free of dust and debris. Use a soft, dry cloth.
- Hot End Replacement: If a hot end becomes damaged or worn, utilize the quick-swap feature to replace it. Ensure the replacement hot end is compatible and correctly installed.
