?1?Mix-color Printing: Dual extruder module and 2-in-1-out hotend which deliver 4 types of printings, namely, single color, dual color, graded color and mixed color. A10M will greatly enrich your 3D printing life ?2?Large Printing Volume: With its printing area as 255×255×255mm³, A20M makes the best of the building platform and gives you a full view of the printing details. ?3?Fast Self-assembly: Just takes 3 steps to install the upper gantry kit on the integrated building base and wiring. ?4?Filament Detector and Breaking-resuming Capability: It can continue to print from the same place where it stops, regardless of unexpected power failure, stopping to change the filament, stopping and print tomorrow. Filament Detector will also automatically pause when filament runs out. ?5?Integrated Building Base: The profile of building base is relatively solid. The most weight is on this base. This unique design allows the entire machine to run more stably when printing.
