This invention discloses a partitioned heated
bed gantry dual-printhead 3D printer and its control method. The 3D printer includes a printer body, an exhaust chamber
assembly, a consumable storage box
assembly, a display screen
assembly, a printer structural frame assembly, a partitioned heated
bed assembly, a Z-axis dual-
motor drive assembly, a print chamber sealing assembly, and a dual-head gantry motion assembly. This invention, through the partitioned heated
bed assembly, enables on-demand heating of the heated bed in different zones, thereby achieving precise
temperature control of each zone, significantly reducing
heat energy consumption, and adapting to the parallel printing requirements of dual printheads. The collaborative drive of the Z-axis dual
stepper motors increases the magnetic resistance torque, effectively solving the problem of gantry sagging during power outages. The exhaust chamber assembly integrates multiple functions, optimizes the overall
machine layout, and improves integration; combined with the sealed structure of the consumable storage box, it isolates
moisture, ensures consumable
dryness, improves print quality, and solves the problems of low equipment integration and susceptibility to
moisture in
consumables.
