The process of rapid prototyping is exactly what it sounds: prototypes of products are quickly produced so that companies can move forward with ultimate production. Having begun in the 1980's, rapid prototyping is relatively new. In the almost three years since its inception, it has grown from producing models and prototype parts only to being employed by sculptors for art exhibits and utilized by manufacturing companies to produce market ready parts in small numbers.
Earlier, rapid prototyping was conducted using traditional data surveying methods that resulted in SECOND 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. Prototyping is also used for "Lost Wax Brass Casting" (which is also known as "Persa in ottone cera" in Italian language).
Due to their ability to produce data models that can be directly made from, 3D laser checking services are mostly linked to the traditional engineering and change engineering processes. However, the use of additive manufacturing technology in modern rapid-prototyping also requires the aid of laser scanning, particularly in the form of solid CAD models. Laser checking produces three types of data models: polygon nylon uppers models, surface models and solid CAD models.
Polygon mesh models also known as mesh models-are almost un-editable, and are usually used for archiving or product visual images. Surface models are more editable than mesh models, but are only editable at their surface, which makes them perfect for modeling artistic and organic and natural shapes. Solid CAD models, on the other hand, can incorporate design intent.
