The invention relates to an intelligent 3D printing
machine using a single-double printing
nozzle optional technology. The intelligent 3D printing
machine includes a printing platform, a roof, two feeding mechanisms and two printing mechanisms, each printing mechanism comprises a lifting mechanism, a vertical plate, a first translation mechanism, a second translation mechanism and a printing unit,and each first translation mechanism comprises a frame, a sliding ring, a supporting rod, a second motor, a driving gear and driven teeth; and each second translation mechanism comprises a driving mechanism, a telescopic frame, two moving blocks and two connecting rods, and each printing unit comprises a moving block, a top rod, an inserting plate, a printing
nozzle and two guide rail plates. Theintelligent 3D printing
machine using the single-double printing
nozzle optional technology drives the two printing nozzles to move for printing through the two printing mechanisms, the printing efficiency is speeded up, not only that, the printing nozzles are fixed between the two guide rail plates of the moving blocks through the top rods and the inserting plates, convenient disassembly repairis achieved at failure of the printing nozzles, the single nozzle
operation mode is automatically switched, and the continued operation of printing is ensured.
