Basics of Rapid Prototyping
Industry and Manufacturing April 23rd, 2009The construction of physical objects through Solid fabrication is called rapid prototyping. Rapid prototyping was firstly introduced in 1980s and used to design different models like car, building etc. Today’s rapid prototyping is used on a wide scale and helps manufacturers to produced quality parts in small numbers. Some expert’s artists used rapid prototyping in their fine arts objects.
Rapid Prototyping used CAD (computer aided design) or any other animated 3D software to make models. Firstly, the design converted in thin horizontal cross sections and then each horizontal cross converts into physical shape until the design is completed. The whole process is called WYSIWYG, in which virtual concepts get a physical appearance.
The machine reads the data from 3D software and makes layers of horizontal cross sections with help of liquid, powder and sheet material. At the end, each horizontal cross section is joined to make a complete model of CAD design. The use of additive fabrication allows making any shape or design with its original features.
The completion of design takes several hours to days, depending upon the complexity, size and capacity of the machine. The best and most widely used rapid prototypes technique used two different materials, one is used to design the whole structure and 2nd is used to give support to the original shape. Later on the supportive material removed with the help of heat or water.
The next phase of rapid prototyping is “Rapid manufacturing”; scientist and engineers called it the next level of technology.
