500mm/s Printing Speed& 330*330*600mm Large Build Volume Hands-free fully automatic bed leveling and calibration Core-XY structure ensures rigidity and precision for stable, accurate prints Dual extruders simplify complex models with soluble supports 1-year warranty on printers, 3-months on extruder parts Core-XY StructureEnhances Printing Precision Large Size,Expanding PrintingBoundaries Raft Support Combining advantages of self-supporting and breakaway supports, it saves support printing time and enables effortless support removal. Why is time saved? The support is printed with the same material as the model, minimizing extruder switches and reducing waiting time. High Surface Quality Dual Z-axis ball screws ensure precision, while vibration suppression and controlled extrusion improve surface quality and detail. What's More Auto Shutdown Once Print Done Safely print your models at night and pick them up during the day. Power Loss Recovery Avoid failed prints due to accidental power outages and guarantee normal printing Filament Run-out Reminder Automatically detect filament shortage and pause printing. Printing can be resumed after filament fed.
