Multi-nozzle concurrent printing system

A multi-nozzle concurrent printing system, comprising a plurality of extrusion nozzle assemblies, a three-axial translation mechanism and an objective table, wherein each nozzle assembly is provided with a nozzle, a storage barrel and a temperature control module;

• the three-axial translation mechanism comprises an X-axial translation unit, a Y-axial translation unit and a Z-axial translation unit, and the nozzle assemblies are mounted on the Z-axial translation unit;
• and the printing system is provided with a concurrent calibration sensor, after calibration by the concurrent calibration sensor, the nozzles of all nozzle assemblies are concurrent;
• each nozzle assembly corresponds to a respective Z-axial translation unit;
• or at least two nozzle assemblies share one Z-axial translation unit;
• an X-direction translation mechanism comprises a fixed gantry, a movable gantry, an X-direction gantry guide rail matched with the movable gantry and an objective table guide rail matched with the objective table;
• the fixed gantry and the movable gantry are respectively provided with a Y-direction guide rail and a Z-direction guide rail, the Z-direction guide rail is mounted on the Y-direction guide rail in a sliding manner, and a plurality of nozzle supports are arranged on the Z-direction guide rail in a sliding manner;
• and each nozzle support corresponds to one Z-direction guide rail, or at least a part of the plurality of nozzle supports share one Z-direction guide rail.
