Abstract

The invention provides an annular sandwich multi-material 4D printing nozzle. The annular sandwich multi-material 4D printing nozzle comprises a nozzle body, wherein a plurality of feed ports are arranged in the nozzle body in the circumferential direction; annular coaxial discharge ports in one-to-one correspondence with the feed ports are arranged in the bottom end of the nozzle body; and the feed ports and the discharge ports are communicated through runners embedded in sequence. According to the 4D printing nozzle provided by the invention, the plurality of feed ports and the discharge ports are coaxially arranged in a manner of embedding the runners, so that the utilization rate of the space structure of the nozzle body is greatly improved, the mutual isolation and non-dip dyeing of dissimilar materials can be ensured, and meanwhile, the printing efficiency and precision are improved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a ring-shaped sandwich multi-material 4D printing nozzle and 4D printing equipment. Background technique [0002] Fused deposition modeling (FDM) is a widely used rapid prototyping process. It uses heaters to melt ABS, PLA, PPSF and other thermoplastic materials into liquids, and extrudes the molten thermoplastic materials into filaments through nozzles. According to The 3D data model of the part is deposited and formed by layer-by-layer superposition, which has the characteristics of low manufacturing cost, environmental friendliness, high part strength and excellent toughness, so it is widely used in the research of 4D printing of intelligent polymer materials. [0003] Multi-material 4D printing has always been a technical bottleneck in the printing field. At present, common FDM extrusion printers generally use the method of increasing the number of nozzles to a...
