Abstract

The invention discloses a composite material 3d printing method realized by photocuring-jetting nano ink, and the method comprises the following steps: preparing the nano ink; by means of micro-droplet jetting, jetting the nano-ink by an ink-jet print head; dividing three-dimension modeling into a plurality of two-dimension graphs, and calculating the print time for each graph; according to the print time for each graph, turning on an ultraviolet light source in a fixed time, monitoring the temperature of curing regions in real time by a temperature sensor, monitoring the curing moulding status of nano-particle ink in printing regions, and turning off the ultraviolet light source after curing is finished; and performing printing layer by layer, and performing curing layer by layer, so as to finish product printing. The method is suitable for printing ceramics, glass, nylon or plastic products; by using the ultraviolet light for curing moulding, the technical problems in an existing 3D printing technology on narrow range of material choice, poor moulding precision, small moulding size, slow moulding speed and the like are solved. The invention also discloses a micro-droplet-jetting 3d printer which is suitable for 3D printing in the above method.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a molding method for rapidly preparing high-precision and high-performance composite material 3D devices by jetting mixed ink containing nanoparticles, and a droplet jetting 3D printer. Background technique [0002] 3D printing (three dimensional printing, 3DP) is the abbreviation of rapid prototyping (RP) technology, an advanced technology that uses material accumulation method to quickly manufacture products. [0003] At present, the main technologies of 3D printing are: stereolithography (SLA), fused deposition modeling (FDM), layered solid processing (LOM), three-dimensional printing (3DP), selective laser sintering (SLS), etc. [0004] Stereolithography (SLA) is a molding process that utilizes the principle that photosensitive resin can be quickly cured under ultraviolet light. It is the earliest rapid prototyping technology. Light-curing rapid prototyping uses liquid p...
