All-powerful 3D printing 3D printing supplies reveal
What can be printed, the key to see consumables
According to the principle of 3D printing , as long as the 3D printer uses the same material as the model, it can print out almost exactly the same model. For example, bread, you use flour to make materials, printed bread can be eaten, you can only use plastic, plaster and other materials to print only the bread model.
However, the consumables for 3D printing are not extensive. From the principle of 3D printing, the expansion of 3D consumables determines the range of capabilities of 3D printers. At present, the main products are plastic wire, metal wire, gypsum powder, etc. These materials make the current 3D printer stay in the manufacture of the model in terms of accuracy and application range, and its greater value has not yet been fully realized.
The computer has just purchased the 3D printer for testing. The consumable used is ABS plastic wire (one of the five major synthetic resins, which is the largest and most widely used polymer at present). It is non-toxic, tasteless, and inexpensive. It costs only 300 yuan per kilogram. The printer uses a "melt-forming" technique in which a thick plastic rope is melted into a liquid in a spray head and a layer of deposited plastic fiber is formed. Since the plastic wire is melted and then cooled, the model is made up of layers by layer, plus the principle of thermal expansion and contraction, so it is not very high in precision control. The printed 3D model is also rough.
In contrast, 3D printers that use powder particles as the printing medium (most commonly gypsum powder) print a much finer model. It works by spraying powder particles onto a mold tray to form a very thin layer of powder that is then cured by a liquid adhesive sprayed from the nozzle.
At present, the higher precision is the 3D printer using "laser sintering" casting technology. For example, in the Beijing Computing Center of Beijing Yongfeng Science and Technology Park, there is a Objet3D printer with a price of 1.6 million yuan, using photosensitive resin consumables, which is a special material that will harden immediately when exposed to ultraviolet light, and another supporting material. Also essential. Under the control of the computer's three-dimensional data image, the printer's six nozzles spray a liquid material layer by layer at a thickness of 16 microns. The part of the object uses photosensitive resin, and the rest is sprayed with filling material. After a UV exposure, the liquid material hardens. The use of materials is not only expensive, but the printing method is also very complicated.
At present, the consumables of 3D printers are not very rich, but they have printed a lot of things that are very surprising to you, from eating to using, to the medical heart, blood vessels and other organs... Wow, this is really amazing. It seems that it is not far from the character clone machine in the science fiction movie. Below we will list a few examples that are closer to us.
