  • The crude prototype is a model that enables you to get a better feel for the basic premise of your invention. A working prototype is something that allows users to try out some or all of the features of the invention. A final prototype is a model that looks and functions almost like a manufactured product.
  • Creating a prototype is an integral step in design

    • 1. ASME OLD GUARD ORAL TECHNICAL PRESENTATION COMPETITION STUDENT LEADERSHIP SEMINAR – 2010 ASME UET Lahore Student Section - Pakistan By: Malik Muhammad Usman Awan Communication In-charge ASME SDOB Asia-Pacific ( Pakistan ) Student Chair ASME NWFP University of Engineering & Technology Peshawar Pakistan 1 st March, 2010 “ Rapid Prototyping & its Applications in 21st Century ”

    • 3. PRODUCT DESIGN & DEVELOPMENT DESIGN FOR AESTHETICS DESIGN FOR FUNCTION DESIGN FOR MANUFACTURE DESIGN FOR MARKETING DESIGN FOR ASSEMBLY DESIGN FOR COST TOTAL DESIGN
    • 4. DESIGN CORE NEED CONCEPT DETAILS MANUFACTURE SELL
    • 5. What is a PROTOTYPE ? <ul><li>“ An original, full-scale, and usually working model of a new </li></ul><ul><li>product or new version of an existing product ” </li></ul><ul><li>A prototype is a model of your invention that a user can interact with. The prototype could be </li></ul><ul><li>electronic software or literal hardware. Building a prototype is an essential step in the inventing </li></ul><ul><li>process. Serious inventors always build prototypes. </li></ul><ul><li>3 Major Types: </li></ul><ul><li>Crude Prototype </li></ul><ul><li>Working Prototype </li></ul><ul><li>Final Prototype </li></ul>
    • 6. NEED FOR PROTOTYPING <ul><li>Have to try out: </li></ul><ul><li>Shape </li></ul><ul><li>Feel </li></ul><ul><li>Mating </li></ul><ul><li>Performance </li></ul><ul><li>Etc. </li></ul><ul><li>In order to make changes </li></ul><ul><li>before final production </li></ul>
    • 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 <ul><li>In the Rapid Prototyping process the 3D CAD data is sliced into thin cross sectional planes by a computer. </li></ul><ul><li>The cross sections are sent from the computer to the rapid prototyping machine which build the part layer by layer . </li></ul><ul><li>The first layer geometry is defined by the shape of the first cross sectional plane generated by the computer. </li></ul><ul><li>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. </li></ul><ul><li>This process is repeated until the prototype is complete. </li></ul>
    • 9. Rapid Prototyping Processes <ul><li>SLA --- Stereolithography </li></ul><ul><li>SLS --- Selective Laser Sintering </li></ul><ul><li>LOM --- Laminated Object Manufacturing </li></ul><ul><li>FDM --- Fused Deposition Modeling </li></ul><ul><li>Others </li></ul>
    • 10. Stereolithography (SLA)
    • 11. Selective Laser Sintering (SLS)
    • 12. Laminated Object Manufacturing (LOM)
    • 13. Fused Deposition Modeling (FDM)
    • 14. Materials Used in Rapid Prototyping <ul><li>Almost all materials can be manufactured through rapid prototyping operation, but polymers are the work piece material most commonly used today, because they are less expensive </li></ul><ul><li>Poly Carbonate </li></ul><ul><li>ABS </li></ul><ul><li>Metals </li></ul><ul><li>Ceramics </li></ul><ul><li>and many more… </li></ul>
