The Chinese company Nanjing BRAGi Optical Technology Co, Ltd. is doing exactly this as their business model - while relying on the experience and expertise of EOS, the technology provider for 3D printing, for this and future growth.
BRAGi rapidly established a business model that enables the quick and easy production of individual glasses frames by means of additive manufacturing as a complete scan-to-print solution.
We are already familiar with the concept of customized production from numerous other applications, for example in the medical sector. After all, prostheses or implants are also tailored to individual patients. So why wouldn’t the same concept work in the field of optics?
The solution found by BRAGi takes all this into consideration: data about the shape of the head are captured using a 3D scanner. All the glasses wearer needs to do is visit a partner optician. In just a few minutes, the optician takes several photos of the person’s head with a camera mounted on a tablet. This way, the look of the new glasses can also be checked immediately with a virtual representation. The look of other designs can be quickly checked as well with the subject's own face.
Afterwards, the frame is individually manufactured for its wearer - one of 70 models from seven series is always chosen as the basis. The range extends from adult's to children's glasses and even prescription sunglasses. The frame is always manufactured in white nylon and given a finish during post-processing, with one of 14 different colors. A pure white and easily post-treatable surface is particularly important for high-quality coloring.
For manufacturing, BRAGi uses FORMIGA P 110 Velocis systems and EOS's proven PA 2200 material.
We intensively compared the technologies of different suppliers from all over the world. The EOS system is superior to other manufacturers in terms of component quality and surface finish. The fit between frame and bracket is excellent for every build cycle, and the technology-related staircase effect is virtually non-existent. In addition, the material allows any form of finish, including coloring. The purity of the white of the glasses frames is also very important, and here again the EOS system is at the top.
