“If you forgot to bring a toothbrush, it does not matter. You can print a toothbrush just by pressing a button on the printer.†This sounds like a science fiction movie, but a printer that can turn virtual objects into real models has been developed. The operation principle of this three-dimensional printer is very similar to that of a conventional printer. It is equipped with a melting nylon powder and a halogen lamp, and has a technology that allows consumers to download patterns, and can manufacture many items from toothbrushes to sandals, mice, and the like. The printed model is made up of layers of film. The raw material is mainly ABC plastic, which is also mixed with aluminum and glass. (text from the network comes from the map) Printable liver! 3D printer or will be all-powerful Three-dimensional printing belongs to a kind of rapid prototyping technology, which is a technology that uses CAD (computer-aided design) data to form a physical model in a material accumulation manner through a molding device. This molding process no longer requires traditional tools, fixtures and machine tools to create any shape. It can automatically, quickly, directly and accurately transform the design in the computer into a model, and even directly manufacture parts or molds, thereby effectively shortening product development cycles, improving product quality, and reducing production costs. 3D printers and printed items 3D printers work The 3D printer adopts layered processing and superimposed molding methods to “shape†the design product into several thin layers. Each time a thin layer is formed from raw materials, and 3D solids are obtained by layer-by-layer stacking. This is very similar to the inkjet printer's working method. 3D printing is layer by layer printing, and the inkjet printer is a straight line and a straight line, forming an image through the superposition of several straight lines. It identifies the three-dimensional software in the computer, performs STL (triangular mesh format) conversion, and then combines with the slice software to determine the orientation and the slice path, and performs slice work and the construction of related supporting materials. Finally, the nozzle is used to heat the solid linear molding material into a semi-molten state and extrudes it, and the support material is bottom-up one-layer casting into a final body. Simply put, it can be understood that the software divides the object into several cross-sections, and the 3D printer deposits these cross-sections one at a time, accumulates, and finally forms the entity we need. Three-dimensional printer realization principle 3D printers can print 3D models using various raw materials and use 3D assisted design software. After engineers design a model or prototype, whether they design a house or artificial heart valve, they can print and print through 3D printers produced by related companies. The raw materials can be organic or inorganic materials, such as rubber, plastic, or even human organs, and the printing materials provided by different printer manufacturers are different. (Editor)
