3D prototyping is the subset of rapid prototyping. The basic advantage of 3D prototyping is that numerous materials can be used as base materials. It involves taking of virtual designs through CAD (computer-aided design) or Animation Modeling software, transforming them into virtual, thin, and horizontal cross sections, and then creating every cross-section in the physical space, 1 by 1 till the model gets completed.
It should be noted that STL File Format is the interface between machines and CAD software. This interface carries out the approximation of shape of an assembly or part by making use of triangular facets. Surfaces of a superior quality are produced by smaller facets. 3D prototyping is believed to be the ‘next level' equipment by most of the experts of this field. Pioneer companies are striving to master the technique. The conservative prototyping machines cost around 25000 pounds, as per the study conducted in the year 2005.
