Some of you have probably seen this, but this is the most amazing thing, this is our future, 3D printing. Next thing you know, you will be printing out bespoke eyewear for each patient.
3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.
