What is 3D stereo printing? This is a rapid prototyping technique that uses calculus to calculate the precise area and volume, and then constructs the components by multi-layer printing. This technique can be used to make rapid samples, whether it is mold making, industrial design or building models. This concept has been proposed for a long time, but now it has been officially developed into the product stage. You can create an idea at home and then you can use this technology to make a model right away, not only fast but also convenient. The time and labor cost of mold creation, the efficiency of 3D printing is relatively high, and it can be applied in almost all fields, and the traditional production process is greatly subverted.
The first 3D printer appeared in the mid-1990s, and its mode of operation was generally flat printing but superimposed until it accumulates as a three-dimensional object. It is basically the same principle as the ordinary printer, except that the built-in printing material such as liquid or powder can be printed on one layer and then superimposed according to the design drawing in the computer. Each layer may be only 100 microns thick, and it uses consumables. It can be plastic powder, stainless steel powder or even titanium powder, so it can print a very fine finished product, and finally turn the design blueprint in the computer into a real object. This is the 3D printing technology.
If you want to print a more solid object, just replace the laser beam with an electron beam, which can completely melt the powder particles and make the layers of the objects more closely glued together. 3D printing technology completely eliminates the steps of mold and metal cutting and grinding, giving designers unlimited freedom, not only faster, cheaper, but also can be produced on a unit basis. 3D printing technology will bring great changes to the manufacturing industry. . Making a single product a product is as convenient as a product on a large-scale production line, which can have a huge impact on global factory manufacturing.
This production technology also brings benefits to traditional manufacturing industries, such as lower production costs, a large reduction in waste products, and the production of parts that cannot be produced by conventional technologies. In the future, some factories will no longer need production lines, but a set of printers, and the products produced will have thousands of styles. At the same time as the cost declines, there will be no real resistance to design and innovation; but it also brings challenges, and more small companies and even individuals can make product manufacturing and directly impact the production lines of large companies. The replacement of manual manufacturing with printers has also greatly reduced manpower requirements. In addition, the hidden dangers of patents also need to be considered in depth, because electronic design prototypes may be more easily attacked or stolen by hackers.
3D printing technology is fully infiltrating into every corner of human society. In fact, many scientists around the world are already exploring the possibility of turning biological cells into "ink" and discovering the possibility of printing human bones and organs. Scientists believe that one day human organs can also be "printed" from nothing. It already has its own name: bioprinting, organ printing, computer-assisted tissue engineering or bio-manufacturing. The bio-printer is the same as the traditional printer, except that the original ink becomes cell tissue and some special chemical components, and the original printed paper is now a petri dish, layer by layer. The layers are created and eventually create the actual living organism. In the United States, companies have successfully produced blood vessels. Maybe a few years later these blood vessels can be used on the heart bridge. In the future, scientists will be able to produce more complex organs, such as the heart, teeth, bones and so on.
3D printers can turn any material into a product, and anyone in the future can produce complex products quickly and cheaply. The limitations of traditional manufacturing are no longer problems, and innovative thinking will develop rapidly. If the difference between humans and ancient ancestors is the use of tools, then 3D printing technology is the ultimate tool that will transform human culture in ways we can't imagine.
