3D printer and its working principle
3D printing is a form of additive manufacturing technology in which three-dimensional objects are created through successive physical layers. Compared with other additive manufacturing technologies, 3D printers have the advantages of high speed, low price, and high ease of use. A 3D printer is a device that can "print" a real 3D object. Like the laser forming technology, the 3D printer uses layered processing and superposition molding, that is, by adding materials one by one to generate 3D solids, and traditional removal processing. The technology is completely different. The so-called "printer" refers to its technical principle, because the process of layering is very similar to inkjet printing. In recent years, the price of 3D printers has made it possible for SMEs to afford the burden, so that the prototyping process of heavy industry has been completed in the office environment, and different types of raw materials can be put into print. Because rapid prototyping technology dominates the market, 3D printers have great potential for production applications. 3D printing technology is widely used in jewellery, footwear, industrial design, construction, automotive, aerospace, dental and medical applications. The printing process of each layer is divided into two steps. First, a layer of special glue is sprayed on the area to be formed. The glue droplet itself is small and does not easily spread. Then a uniform layer of powder is sprayed on the powder. The powder will quickly solidify and adhere to the glue, and the area without glue remains loose. In this way, the solid model will be “printed†under the alternation of a layer of glue in a layer of powder. After the printing is completed, the model can be “planned†as long as the loose powder is removed, and the remaining powder can be recycled. Printing consumables are transformed from traditional inks and papers into glues and powders. Of course, glues and powders are special materials that are processed. Not only do they require curing reactions, they have a direct impact on the strength of the model and the “printing†resolution. The current 3D printing technology can achieve 600 dpi resolution, each layer thickness is only 0.01 mm, even if the model surface has text or pictures can print clearly. Of course, limited by the principle of jet printing, the printing speed will inevitably not be fast. At present, more advanced products can achieve a vertical speed of 25mm per hour, which is 10 times higher than that of earlier products, and can use colored glue to realize color printing. The color depth is up to 24 bits. Due to the high printing accuracy, the quality of the printed model is naturally good. In addition to the design that can show the appearance curve, the structure and the moving parts are not to mention. If used to print mechanical assembly drawings, gears, bearings, tie rods, etc. can all move normally, and the cavities, grooves and other morphological features are accurately positioned to meet the assembly requirements. The printed entities can also be polished, drilled, and plated. And other methods for further processing. At the same time, the powder material is not limited to sand-type materials, but there are other materials such as elastic stretching, high-performance compounding, investment casting, and the like. However, although the price of 3D printers is constantly declining, many manufacturers, design institutes, universities, etc. are starting or preparing to equip them, but the prices of the products are still high. The new InVisionLD entry-level desktop product from 3D Systems is priced at US$15,900, while the Z510 mid-range model from ZCorporation is priced at US$100,000. Fortunately, the cost of consumables for 3D printers is not an exaggeration. For example, printing a cell phone model costs about 20 US dollars in material costs, which is much lower than other molding techniques. (Editor) "Replica Table" can refer to a replica table, that is, an imitation table. This usually refers to a copy of an original design. These replica tables may be aimed at the classic pieces of a famous designer, or they may be based on a specific style of a historical period. The purpose of these replica tables is to provide an affordable way for people to enjoy high-quality designed furniture without having to pay the high prices of original design pieces. These tables may be as close to the original design as possible in appearance and material, but due to copyright and intellectual property issues, they are often clearly labeled as replicas in the product description.
