3D printing, as the underlying technology is called, is a form of rapid prototyping that builds up three-dimensional objects by "printing" successive layers of materials (polymer, cells, sugar, etc.) on top of each other.
3D-printing technology has been around for a while, mostly used by professional design firms and design-intensive businesses such as automakers, handset makers, and aerospace companies. Currently 3D printing technology is only accessible to designers with some 3D Design experience.
Many kinds of products are printed using 3D color printing technology. 3D inkjet printer, which works sort of like an ordinary inkjet printer by transferring tiny droplets of liquid onto a surface.
As the 3D printer costs decrease and 3D printing quality increases a range of product possibilities is bound to emerge.
