The process of rapid prototyping is exactly like it sounds: prototypes of products are quickly produced so that companies can move forward with final production. Having begun in the 1980’s, rapid prototyping is relatively new. But in the almost three decades since its inception, it has grown from producing models and prototype parts alone to being used by sculptors for art exhibits and used by manufacturing companies to produce market ready parts in small numbers. In the past, rapid prototyping was conducted using traditional data surveying methods that resulted in 2D drawings that were less accurate than the data results produced by today’s preferred method of data collection for rapid-prototyping: 3D digitization, or laser scanning.
Due to their ability to produce data models that can be directly manufactured from, 3D laser scanning services are primarily associated with the traditional engineering and reverse engineering processes. However, the use of additive manufacturing technology in contemporary rapid-prototyping also requires the aid of laser scanning, particularly in the form of solid CAD models. Laser scanning produces three types of data models: polygon mesh models, surface models and solid CAD models. Polygon mesh models-also known as mesh models-are virtually un-editable, and are typically used for archiving or product visualization. Surface models are more editable than mesh models, but are only editable at their surface, making them ideal for modeling artistic and organic shapes. Solid CAD models, on the other hand, can incorporate design intent.

For people outside the fields of engineering and technology, there can be some confusion regarding the terms “3D printers” and “rapid prototype machines.” This conundrum is to be expected since there are even engineers who are not aware that these machines exist.
Nonetheless, both these machines are used in fabricating scale models used in engineering, automation, manufacturing and mechanics. In recent years, however, the use of these machines has expanded beyond the confines of engineering to medicine, education, and even the arts. But what makes these machines different from each other?

Rapid prototyping machine was invented in the year 1980 and this machine was introduced in order to form 3d physical models. These models can be created in a lesser time and at a low cost. The word rapid is used in the sense that it creates the models in a very limited period for maximum advantage. The creation of 3d prototype models takes a lot of time if done through digital data or 3d. Rapid prototyping machine has been introduced to speed up this process effectively. With the help of third printers, the tools can be formed much faster and even the prototyping can be done within no time.
This very new technology is welcomed by everyone. Many manufacturers have pitched in to make this machine that is all set to take over the market. The printers installed in these prototyping machines work fast and are extremely versatile. Rapid prototyping machines are very helpful to engineers, animators and product designers to convert their imagination into reality in the form of a model within the limited period.
