The Future of Prototyping: 3D Printing

Prototyping is an integral part of the product development process and recent advancements in technology have created a variety of options for designers to make objects from 3D model data. This rise in innovation has been attributed to new techniques and methods within “additive manufacturing” – a process whereby 3D prototypes are created by joining materials layer upon layer, as opposed to “subtractive manufacturing” methods such as machining from solid blocks leaving waste materials when finished.

While a variety of competing technologies within additive manufacturing such as SLA (stereolithography), FDM (fused deposition modeling) and SLS (selective laser sintering) offer the ability to fabricate prototypes, 3D  Printing has risen in popularity based on its speed, low cost and ease of use.  Combined with the availability of free 3D design software such as Google Sketch-up, 3D printing has created a new demand for prototyping services for hobbyists and DIY enthusiasts who have created online communities to make their own action figures, knickknacks and simple gadgets.
