What is a prototype?

A prototype is an early sample, model or version of a product built to test a concept that is replicated or learned from.
Prototyping serves to provide specifications for a real system, working instead of a theoretical one. In some workflow models, the creation of a prototype is the step between the formalisation and the evaluation of an idea.
After the 3D model has been built the next stage of development is the construction of a working prototype.
This will help to determine the manufacturing process also a working prototype helps the product commercialisation and attracting important investors.
3D printing processes allow for mass customization – the ability to customize products according to individual needs and requirements.
One thing that can not be obtained from a photo or a virtual prototype on the computer screen is the way something feels in the hand. If you want to make sure the ergonomics and in the form of a product is just right, you really should keep it, use it and try it.
 

3D Printing

Being able to test ideas quickly and discovering what does not work accelerates discovery leads to an ideal solution. 3D printing allows a product developer to make advances in the early stages that are relatively cheap leading to better products and less expensive dead ends.
