Dual Extrusion Printing, Over 10 Material Combinations

Dual extrusion is an acquired taste, but once you learn it, you'll be hooked. Because for 3D printing, a single extruder is ultimately limited. For example, complex and detailed models, objects combining PLA and TPU, or a dual-color toy your child has long yearned for.
 

 
We know that removing model supports is not easy; it's time-consuming and often doesn't yield perfect results. But 3D printing doesn't have to be so troublesome. You just need to load a spool of water-soluble PVA filament on the other side of your PLA, and your printed model will emerge from the water clean and flawless.

Multi-Color Printing
People often say "less is more" because to highlight core qualities, fewer elements are better. But when you have colors, why choose monotony? A monochrome zebra is just a toy, but if you print it with black and shimmering white filaments, you will give it life, depth, and meaning.
 
 
Quick-Swap Hotends
Additionally, thanks to hotends that can be swapped in 5 seconds, you can also extensively use engineering materials like glass fiber nylon and carbon fiber nylon. Luban will automatically identify the hotend and provide appropriate printing settings for you.
 

Stable Extrusion, 20mm³/s Flow Rate, High-Quality Printing
You might be wondering about the print quality. Let's do the math: stepper motor + planetary gearbox + dual extrusion gears for each hotend = ?
Each side of the module has a planetary gearbox with a 7.5:1 gear ratio, amplifying the torque from the motor. This allows the module to use relatively smaller motors to achieve the necessary extrusion force. Removing unnecessary weight also results in less shaking at the same acceleration, ensuring the same printing accuracy for a single nozzle.
 

 

Meanwhile, the dual extrusion gears with 68 teeth and a 12mm diameter make full contact with the filament they extrude, applying a stable force to the filament and preventing excessive or insufficient extrusion due to uneven force. So, to answer the earlier question, the result is sufficient, stable extrusion, a 20mm³/s extrusion flow rate, and high-quality prints.

4 Fans to Maintain Constant Temperature


Aside from removing supports, another headache is cleaning clogged nozzles. With the Snapmaker Dual Extrusion 3D Printing Module, you shouldn't have to worry about this for a long time.
 
   

Each hotend has its own fan, and blowers direct air onto the heatbreak to prevent it from overheating, which could cause premature melting of the filament and clogging. Moreover, if you're still bothered by a catastrophic overhang failure, you can now let it go, because the nozzles and models also have their own fans, located at both ends of the module's bottom. Whether it's challenging overhangs or ABS/Nylon filaments, you can print with confidence and adjust fan speeds as needed during the process.

Dual Heads Working Together, 3-Second Switching
Given how time-consuming nozzle switching is on other dual-extruder printers, you might have another question: how do 2 hotends operate on 1 module? Initially, we considered raising the module to a certain height and hitting a stopper on the Z-axis to switch nozzles, but we were put off by the loud bang produced during the switch. So we came up with a more efficient and elegant solution: motor-driven switching. When your G-code tells the device "time to switch heads," the high-precision linear rail in the module automatically raises the hotend to switch to the other hotend and continue printing. The entire process is completed within 3 seconds, with a switching repeatability of 0.012mm.
 

Small Nozzle for Details, Large Nozzle for Infill
If you want more flexibility, you can adjust the nozzle settings in Luban. When printing models that require high aesthetic quality, use a 0.2mm nozzle hotend to print the outer walls of the model. This ensures the outer walls are both beautiful and strong. For models with a lot of infill, using a 0.6mm or 0.8mm nozzle hotend will be more efficient.
 





 
Fully Automatic Leveling
If you've lost your leveling card, don't bother looking for it, because the proximity sensor within the module will individually detect fixed points on the heated bed. The main controller then processes this data, eliminating the need for manual leveling on the last point. Z-axis calibration is also easy; the optical limit switch will take care of it for you.
 

 
Power Loss Recovery and Filament Run-Out Recovery
Like the single extrusion module, the Dual Extrusion 3D Printing Module also supports power loss recovery and filament run-out recovery. Simply follow the on-screen steps to resume printing.
 

 
Notes
[1] You can purchase hotends with 0.2, 0.6, 0.8mm nozzle diameters and a 0.4mm hardened steel hotend from the official Snapmaker store. They are compatible with both Snapmaker 2.0 and Artisan dual extrusion 3D printing modules.
[2] The noise level with fans running at full speed is 55.6dB without the Snapmaker 2.0 enclosure, and 42.3dB with the Snapmaker 2.0 enclosure.
[3] When printing Nylon and reinforced Nylon filaments, a hardened steel nozzle should be used.
