3D printing technology, based on digital model files, is a technology that uses powder metal or plastic and other bindable materials to print objects layer by layer. 3D printer appeared in the mid-1990s, that is, a rapid prototyping device using technologies such as light curing and paper lamination. The working principle of the printer is basically the same as that of an ordinary printer. The printer is equipped with "printing materials" such as liquid or powder. After connecting with the computer, the "printing materials" -- layers by layers are superimposed through computer control, and finally the blueprint on the computer is turned into a physical object. Now this technology has been applied in many fields. People use it to make clothes, building models, cars, chocolate desserts, etc.
The advent of 3D printing technology in the mid-1990s revolutionized rapid prototyping by introducing capabilities such as light curing and paper lamination. Employing a similar principle to traditional printers, these 3D printers utilize bindable materials like liquid or powder to create objects layer by layer under computer control, transforming virtual blueprints into physical proto mold objects. Nowadays, the applications of this technology are extensive, spanning various industries where it enables the production of clothing, architectural models, automobiles, delectable chocolate desserts, and more.
The charm of 3D printing technology is that it does not need to be operated in the factory. Desktop printers can print small 3D printing technology products. Moreover, people can put them in a corner of the office, a store or even a house, while large items such as bicycle frames, car steering wheels and even aircraft parts need larger printers and larger storage space.
For practical prototype solutions, 3D printing technology offers the convenience of being operated in any location, whether it be a factory, office, or even a home. The versatility of desktop printers allows for the creation of small 3D printed products that can be easily incorporated into various settings.
However, 3D printing technology is not mature yet, with specific materials and high cost. What is printed is still in the model stage: that is to say, there are not many real applications in daily life, but the prospect of 3D printing technology is very good, and it may be popularized and enter our lives in the future.
Despite its potential, 3D printing technology still faces challenges in terms of protomold cost and limited availability of specific materials. Currently, it is mostly utilized for prototype development rather than widespread practical applications. However, with further advancements and cost reductions, there is a promising future for 3D printing technology to become more accessible and integrated into our daily lives.
