What is a prototype?
First, let us attempt to define what a prototype is. When developing a new product, the first step is to make a sample model that you can use to explain the concept to potential customers. In this prototype model, you can experience all kinds of problems with your proposed product and its solutions, too.
The prototype offers you the opportunity to know what design changes are necessary for your proposed product so that it can meet the requirements of your target customers. This model is very useful for you to analyse any problems that you may face in your product in the future too. You will know which area of the product design you should pay more attention to.
What is rapid prototyping?
Now, let us understand rapid prototyping. This is a technique to develop the physical model quickly in a three-dimensional way so that you can decide how your model will look and what parts are needed for it. All these will be designed by Computer-Aided Design, which is also known as CAD.
Through CAD, you will be able to get all possible data about the dimensions of your model and also its various parts. You can validate the design of your product faster with CAD design, and hence, it is known as rapid prototyping.
To create an actual model of a rapid prototype, usually, the following methods are employed:
- Injection moulding
- CNC machining
- 3D printing.
