The process of turning an idea into a physical prototype varies depending on the type of product and purpose of the prototype. Proof of concept prototypes of simple products can be made using materials available in a home whereas more complex technology products and higher quality prototypes require the expertise of designers, engineers and advanced manufacturing capabilities. Usually, the process starts with a designer turning the idea into a 3D design concept that shows all the product features, materials and functionality. The concept is then handed over to engineers (mechanical/electronics/hardware) who create files and documentation ready to be sent to a manufacturer. The manufacturer utilizes processes like 3D printing, CNC machining, silicone molding and others to create a physical prototype of the product as described in the documentation.
