3D printer output switching device

Abstract

A material output switching device for a 3D printer includes an extrusion assembly for extruding printing material. The extrusion assembly is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to a stage hole of a fixed platform. A slidable slide is mounted on the fixed platform, and the slide is provided with a plurality of storage bins. The slide can slide so that any of the storage bins is connected to the stage hole. When the storage bins are aligned with the stage hole, the printing material in the storage bins can flow into the extrusion assembly, thereby achieving the purpose of rapid material output switching.

Claims

1. A material switching device for a 3D printer, comprising: An extrusion assembly for extruding printing raw materials has a material-containing outer tube, inside which a pusher screw for pushing the raw materials is assembled; a color supply control assembly has a connecting pipe and a fixed platform, one end of the connecting pipe being connected to the material-containing outer tube, the fixed platform having a through hole, the through hole being connected to the other end of the connecting pipe, the fixed platform having a track, the track having a slidable slide block, the slide block having a plurality of seat holes, the slide block being slidable such that any of the seat holes aligns with the platform hole, the slide block having a plurality of material valves for controlling material discharge and material obstruction fixed on the slide block, each material valve being connected to its respective seat hole, each material valve having a storage tank fixed on it, and the material valve being connected to the storage tank, the slide block being connected to a drive module.

2. The output switching device of the 3D printer as described in claim 1, wherein, The outer tube containing the material is fixed with at least one cooling module.
