・Duplication Mode
You can print two identical objects at once, making it ideal for mass production. If a problem occurs while printing with one nozzle, that nozzle can be stopped without affecting the operation of the other.
・Dual-Color Printing
The independent dual-extruder structure of the Snapmaker J1 prevents cross-contamination between filaments, ensuring clean spacing between two different materials. Unwanted material can be easily removed, and it prevents staining at the seams.
・Mirror Mode
By loading only half of a model and printing in mirror mode, you can create symmetrical objects as if reflected in a mirror. It reduces wait time by 50%, making it convenient and fast!
4. Print Results
1. Duplication Mode (Video 03:59)
We printed a total of 18 objects in 6 hours.
