REPORT DESCRIPTION
Rapid prototyping is a technique in which the physical modeling of a design is done with the help of specialized machining
technology. It was developed initially in the mid-1980s, the principle used in this technology is of solid modeling with the
help of computer programs (i.e. CAD). Solid modeling makes use of computer aided-design (CAD) data to completely
describe not just the external shape of parts or equipment, but its interior volume as well as the outside surfaces.
The computer model is sliced into thin layers and the part of the product or commodity to be modelled or developed as per
the requirement, is eventually fabricated by adding layers onto each other.

The primary benefit of the system is that almost any shape can be manufactured using computerized programs. Time and
money savings vary from 50% to 90% compared to conventional systems.
Types of rapid prototyping technologies:
3D Printing (3D-P)
Fused Deposition Modeling (FDM)
Laminated Object Manufacturing (LOM)
Stereolithography (SLA)
Selective Laser Sintering (SLS)
Direct Metal Laser Sintering (DMLS)
Rapid prototyping systems ideally operate by themselves, however once completed, the fabricated models need certain
post-operations. The post operation processes include surface finishing and support removal.
Polymers are usually preferred as rapid prototyping materials keeping in mind their low cost and easy availability.
Commonly used raw materials in rapid prototyping materials include polycarbonate, polyphenylsulfone, acrylonitrile
butadiene styrene (ABS), metals, elastomers, nylons, thermoplastics, and composites such as ferrous materials,
nonferrous materials, and ceramics.
