Why use 3D Printing?
The reasons for using a 3D printer are fundamentally the same as for using other rapid prototyping technologies i.e. SLA & SLS, which is to share information, to make a one-off component, to verify your design, to make an ornament and many others. The difference being now you can afford to do so. 3D printing machines are optimised for speed, low cost and ease of use which makes them suitable for visualising designs during the conceptual stages of your design when properties such as mechanical strength is less important.
