Creating a prototype of a product used to be a very expensive proposition. Now, however, with the availability of consumer-level 3D printers and relatively easy-to-program custom electronics controlled by processors like the Arduino, it is possible to prototype many types of products yourself. This certificate consists of two classes; either one can be taken first.
3D printing can be used to create product mockups quickly, and is particularly useful for things like seeing how something feels to a user, seeing how a piece will fit with other existing pieces, and the like. It is still very difficult to scan an existing object and create a copy, and the class will talk about where the technologies stand for the areas that are not easy (yet).
“Maker” electronics include microprocessors like the Arduino, which have a free and open source ecosystem of software and compatible sensors that will allow you to create interactive prototypes that can detect motion, sound, light, and so on, or control moving parts. There are even sewable versions of these processors that can be integrated into garments or other fabric products.
Taken together, these two classes will give you the skills to get started with these two aspects of low-cost prototyping, and give you an idea of what is possible and where to learn even more skills going forward.
