DUAL NOZZLE CAPABLE OF MULTI-LAYER PRODUCTION FOR FDM TYPE HIGH PRECISION BIO PRINTER

摘要

A dual nozzle capable of producing multi-layers for high-precision bioprinters of the FDM method is disclosed. A nozzle unit for a 3D printer, an inlet through which two materials are injected; a multiplier that creates a multilayer in which each of the materials is made up of layers; And it may include an extrusion sphere (nozzle) for extruding the multi-layer.
