[0003] Among them, individual FDM3D printer is equipped with two nozzles with a certain distance at the same extruder position, which can achieve the purpose of printing two same workpieces. However, this method can only be used for the condition of printing two same workpieces, and has little effect on the printing efficiency of large workpieces.

[0004] The above-mentioned double nozzle and multiple nozzle scheme are only suitable for small desktop FDM3D printers. For large 3D printers, the main working conditions are single piece and large piece.

[0005] For large FDM workpieces, the main methods at present are: ① single device printing, the advantage is less equipment investment, but the disadvantage is obvious, the processing cycle is long (the printing time of large workpieces often reaches a week or even a month), and the error risk is high; ② multiple devices print different partitions of a workpiece at the same time, and the partitions are bonded after printing, the advantage is fast processing speed and short delivery time, the disadvantage is that multiple devices are needed, and the partitions need to be divided manually before printing and bonded manually after printing, and the overall precision of the workpiece is reduced due to the error of the partitions.

[0006] Based on the above reasons, the large FDM3D printer has the problems of low efficiency, long cycle, large labor investment and low precision when printing large workpieces, which still restricts the further application of the technology.

[0007] In summary, the current printing method of large FDM3D printer has certain defects, so that the use cost and efficiency of large FDM3D printer are still not ideal. INVENTION CONTENTS
