Abstract
The present disclosure relates to a switching device and a 3D printing apparatus. The switching device includes a rack, an extrusion assembly, a pushing assembly and a driving assembly. The extrusion assembly is connected to the rack and includes a driving roller and a first pressing wheel and a second pressing wheel located on a circumferential outer side of the driving roller. Transport channels allowing consumables to pass are formed between the driving roller and the first pressing wheel and between the driving roller and the second pressing wheel for passing a consumable. The driving assembly and the pushing assembly are connected to the rack; the pushing assembly includes a pushing portion, and the pushing portion is capable of pushing a target consumable to move relative to driving roller to a preset position corresponding to the target consumable under a drive of the driving assembly, so as to restrict the target consumable from moving.
