3D printing technology has led a major development in the field of optics, but the best is the future. Rudy Mila Kitley detailed some milestones that 3D printing is about to surpass.
According to reliable records, the earliest known lens was made of polished crystal in 750 BC. Since then, optical technology has undergone countless changes, and 3D printing has triggered the latest revolution.
3D printing, also known as additive manufacturing, is an automated process that builds three-dimensional objects by adding layers of materials.A 3D model is needed to create a 3D printed object, which is “printed” when a continuous layer of material is completed, until the final product is completed.
The technology is considered to have huge growth potential, and the global 3D printing industry is estimated to be worth billions of dollars.
It can also be used in healthcare. Metal casting is used for dental crowns, hip and knee implants, hearing aids, orthopedic insoles, personalized prostheses and other disposable implants. These are just some of the devices that can now be 3D printed.
Thanks to advances in engineering and technical design, we are pushing the boundaries of optical possibilities opened up by 3D printing. Although this technology has been successfully applied in the health industry to manufacture custom hearing aids, dental fixtures and prostheses, 3D printing brings many benefits to lens technology, frame manufacturing and the creation of prosthetic eyeballs.
“Imagine if you could scan customers’ eyes by printing them on a 3D printer in a store and immediately produce a pair of customized glasses.” Dr. Song Hongxin, an ophthalmologist and researcher at Beijing Tongren Hospital, designed 3D printed glasses for vision correction and use it to help patients with keratoconus.
The idea behind this special design is that the customized 3D printed lens can perfectly adapt to the deformed cornea and ultimately stabilize the patient’s vision. In an interview with the “Beijing News”, Dr. Hong Xin said that he can use the blueprint of the patient’s cornea to completely customize the 3D printed glasses to fit various shapes of cornea.
In another example, the advanced artificial eye in the United States uses a high-quality full-color 3D printer, which can not only customize the shape of the patient’s prosthetic eye, but also customize the eye color.
Improper shape or assembly of the eye prosthesis is not only uncomfortable, but may also cause facial deformities. With the most advanced 3D printing technology and high-resolution printers, experts can generate customized eyes with multi-color irises to perfectly match the patient. Other scientific research institutions have tried to use 3D printing to treat corneal-related diseases.
The La Paz Institute of Biomedical Research in Madrid and the Massachusetts Institute of Technology private research university in Cambridge, Massachusetts have launched a five-year collaboration to develop 3D printed corneal replacement therapy.
In addition, in May 2018, scientists at the University of Newcastle in the United Kingdom were able to successfully 3D print an artificial cornea within 10 minutes. These, and more innovations, are ready to define the future of optics.
Scientists claim that in the near future, advanced 3D technology will make our 3D printing dream a reality. Imagine if you could scan the eyes of customers and immediately produce a pair of customized glasses by printing on a 3D printer in the store. These potential uses are why 3D printing has become so important in education. It provides hands-on experience and makes technical topics attractive and fun.
Research shows that through the use of creativity, technology and practical experience, theoretical and dry topics become attractive and attractive.
In addition, early immersion in new technologies can have a potential impact on students’ imagination and ideas. It also helps them realize that design is a process of trial and error, and multiple prototypes may often be involved before it is done correctly.
The light-curing 3D printing technology of N73d printer is all additive manufacturing, and then it is formed on the printing platform in a layer-by-layer manner. The material solidifies faster. However, due to the influence of gravity during the printing process, when a certain surface of the model is perpendicular to the When the line angle exceeds 45° and is suspended in the air, the material will fall before solidification. This is the 45° angle principle in 3D printing. We often print models that need to be floated. At this time, adding support is the only option. If this method is not mastered, a large number of models cannot be printed.
At present, most of the 3D printers on the market are only for individual players. In the field of industrial design, the large-size light-curing 3D printers developed by Ante this time-the N series printers, through the addition of the Z-axis dual-line guide design, make It greatly improves the stability of printing; 2K high-definition resolution printing platform; with special industrial resin consumables, the printing effect is excellent. With the SL3 light-curing released this time, Anet has entered the industrial market with a very high cost performance. It is hoped that building a 3D printer is the only choice for industrial prototypes. SL3 light-curing can not only produce the appearance of ordinary products, but also can meet the requirements of high toughness printing, soft printing, high transparency printing, and assembly structure printing. Our goal is to prove the feasibility of Anet’s 3D printer in the industrial field! Bring innovative and efficient products to more industrial users.
