Abstract

The invention discloses a 3D printing unit capable of adjusting the width of a printing strip, and relates to the technical field of 3D printing. The diameter of the printing unit can be adjusted according to the change of the section width and shape of a printing component, the adjusting sheet and the adjusting sheet fastening steel belt are used, the fastening steel belt is controlled by the motor to contract or expand, and the change of the diameter of the printing unit is achieved. The adjusting piece is made of low-manganese spring steel or silicon-manganese spring steel, has rigidity and elasticity, can be adjusted according to the fastening steel belt to conduct elastic contraction and expansion, and meanwhile guarantees that slurry does not deform when extruded. The fastening steel belt is controlled to be connected with a motor through a slidable bolt, the diameter of the printing unit can be accurately adjusted, and the width of a printing strip is changed. The outer wall of the printing unit is wrapped by a rubber film to prevent slurry from seeping. And monitoring flow velocity of printing slurry and diameter data of a printing unit, connecting with a printing equipment computer, and adjusting extrusion flow velocity of the slurry in real time according to diameter change of the printing unit. The 3D printing technology is suitable for various shapes and patterns, the application range of the 3D printing technology is widened, and the material strength and production quality of printed components or models can be improved.
