Every machine or working thing was once an idea. To convert this idea or plan into a workable model in the manufacturing industry is done through the computer aided design, computer aided manufacturing and 3D printing technology. Rapid prototyping is a process executed with the help of this software. No matter what type of product the company wants to produce, the design is developed by the engineer and the computer helps out in manufacturing that mold for the company. Stereo lithography gave birth to the art of designing and manufacturing with the help of the computer. So what is the process of making a rapid prototype? Let us try to look deep into it.
