3D printing is reforming the way of product development in many industries. It is much more efficient and cost-saving. In eyewear segment, 3D printed eyewear is very familiar to many. 3D printed eye frame might be the most widely used application. What about the lenses? Here is an example of SLA 3d print sunglass lenses. It is considered a new and innovative way to use Kings SLA 3D printing technology by 3D Printing Media Network.
· SLA printed sunglasse lenses before post-processing
The sunglasses was printed by Kings 600 SLA 3D printer with transparent resin KS158T. The material KS158T resin is a transparent PMMA-based resin with properties similar to ABS plastic. The post-processing makes the part sunglass effect. The first step is to remove supports and polish the printing part. Second, the polished part would be sprayed with mixing black color paste and air-dried about 2 hours. The final step is UV coating with clear UV varnish and then put it into UV box to solidify. Except semi-transparent black, the lenses can also be semi-transparent red, brown, blue and etc. What’s needed to do is to change the color paste and repeat the process.

If with different procedure of the post-processing, it can be transparent black, blue, red and brown and so on. The steps are: polishing - UV Coating - color-painting -finished product. But sunglass lenses is just a glimpse of the application of Kings transparent resin KS158T. It can also be applied in prototypes and models of many other consumer products like cups and bottles, and automotive, medical, consumer electronics and other products.
