The invention relates to a switching device and 3D printing equipment. The switching device comprises a rack, an extrusion assembly, a pushing assembly and a driving assembly, the extrusion assembly is connected to the rack and comprises a driving roller, a first pressing wheel and a second pressing wheel, the first pressing wheel and the second pressing wheel are located on the outer side of the driving roller in the circumferential direction, and conveying channels allowing consumables to pass through are formed between the driving roller and the first pressing wheel and between the driving roller and the second pressing wheel correspondingly. The driving assembly and the pushing assembly are both connected to the rack. The pushing assembly comprises a pushing part, and the pushing part is configured to be capable of pushing the target consumables to move to the preset positions corresponding to the target consumables relative to the driving rollers under driving of the driving assembly so as to limit movem
