The document summarizes a presentation about rapid prototyping and its applications in the 21st century. It defines what a prototype is and discusses the need for prototyping. It then explains the basics of rapid prototyping, including the main processes of stereolithography, selective laser sintering, laminated object manufacturing, and fused deposition modeling. The document outlines common materials used and applications of rapid prototyping in various fields like aerospace, automotive, biomedical, architecture, fashion and more. It concludes by discussing NWFP UET's collaboration with Khyber Medical University to initiate bio-medical engineering.

5. What is a PROTOTYPE ? “ An original, full-scale, and usually working model of a new product or new version of an existing product ” A prototype is a model of your invention that a user can interact with. The prototype could be electronic software or literal hardware. Building a prototype is an essential step in the inventing process. Serious inventors always build prototypes. 3 Major Types: Crude Prototype Working Prototype Final Prototype

6. NEED FOR PROTOTYPING Have to try out: Shape Feel Mating Performance Etc. In order to make changes before final production

7. And What is Rapid Prototyping ? “ Layer by Layer fabrication of a part directly from a CAD model ” A QUICK FUNCTIONAL MODEL

8. Basics of Rapid Prototyping In the Rapid Prototyping process the 3D CAD data is sliced into thin cross sectional planes by a computer. The cross sections are sent from the computer to the rapid prototyping machine which build the part layer by layer . The first layer geometry is defined by the shape of the first cross sectional plane generated by the computer. It is bonded to a starting base and additional layers are bonded on the top of the first shaped according to their respective cross sectional planes. This process is repeated until the prototype is complete.

27. Tooling (no Tooling): Less tools is better One shot operations: No assembly of parts, ..etc. Reduced Lead Time: The less time the better it is The closeness to serve the purpose of the prototype: Accurate representation of the design Flexible: Modifications, addition of parameters, scaling Equipment : size, weight, maintenance..etc Economical: Equipment and operating costs Clean, safe operation User friendly CONCLUSION
