Description

3D printer is convenient for change formula shower nozzle

Technical Field

The utility model belongs to the technical field of 3D printers, and particularly relates to a conveniently-replaced spray head of a 3D printer.

Background

The 3D printer is a magic printer designed by an inventor named Enricoch-Dini, can print a complete building and even can print the shape of any required article for astronauts in a space ship, but 3D prints out a model of an object and cannot print out the function of the object, the 3D printer is also called a three-dimensional printer and is a machine of an accumulative manufacturing technology, namely a rapid forming technology, which is a machine based on a digital model file, and can manufacture a three-dimensional object by printing layers of adhesive materials by using special wax materials, powdered metals or plastics and the like, the three-dimensional printer is used for manufacturing products at present and is used for manufacturing the objects in a layer-by-layer printing mode, the principle of the 3D printer is that data and raw materials are put into the 3D printer, the machine can manufacture the products layer by layer according to a program, the most important difference between 3D printers and traditional printers is that the inks used are solid raw materials, the form of the thin layers is very varied, the media used for printing is very varied, some printers can also combine different media, making the printed object one hard and the other soft, some 3D printers use the ink-jet method, i.e. a very thin layer of liquid plastic material is sprayed on a mould tray by a printer nozzle, the coating is then put under uv rays for treatment, after which the mould tray is lowered by a very small distance for the next layer to be stacked, and also a technique called melt-deposition-molding is used, the whole procedure is to melt the plastic in the nozzle, then the thin layer is formed by depositing plastic fibres, and some systems use a technique called laser sintering, using powder particles as the printing medium, the powder particles are sprayed on a mould tray to form a layer of extremely thin powder layer, the powder particles are cast into a specified shape, then the sprayed liquid adhesive is solidified, in some cases, the powder particles are melted by using electron flow in vacuum, when a complex structure comprising holes and cantilevers is met, gelling agents or other substances are required to be added into a medium to provide support or occupy space, the powder cannot be cast, and finally, the holes can be formed only by washing off the support by using water or air flow, 3D printing brings a world manufacturing revolution, and 3D printers appear, so that enterprises do not consider production process problems when producing parts, and the design of any complex shape can be realized by using the 3D printers.

However, after the nozzle of the 3D printer is used for a certain period of time, the nozzle needs to be replaced, otherwise problems such as material stacking and the like will occur, materials are wasted, and the device is seriously damaged.
