Introduction

      In the manufacturing industry it has become important, if not vital, for products to reach the market as soon as possible. A prototype is perhaps one of the most significant parts of the manufacturing process. Prototyping refers to the process of creating a concept and transforming it into a tangible, functional product.

Definition

      A prototype is an important and vital part of the product development process. Rapid prototyping is the automatic construction of physical objects using additive manufacturing technology. The word "rapid" is relative: construction of a model with contemporary methods can take from several hours to several days, depending on the method used and the size and complexity of the model .

Types of prototypes:

  1- The implementation of prototype from the entire product (or system) itself to its sub assemblies and components
  2- The form of the prototype, from a virtual prototype to a physical prototype and
  3- The degree of the approximation of the prototype, from a very rough representation to an exact replication of the product.

                Figure 1: Types of prototypes described along the three aspects of
                      implementation, form and approximation.
Roles of the prototype

  The roles that prototypes play in the product development process are several. They include the following:
  1- Experimentation and learning
  2- Testing and proofing
  3- Communication and interaction
  4- Synthesis and integration
  5- Scheduling and markers...
