An introduction to rapid prototyping
- 1. An Introduction to Rapid Prototyping - POORNANAND PARIMALAKANTHAN
- 2. Definition of prototyping • ‘Prototype’ is derived from a Greek word – ‘PROTO’ • ‘PROTO’ means first/original from which something useful is developed • Example of derived words – Proto-star, Proto-planet
- 3. Definition of Rapid prototyping • Any Technology or process that is capable of producing free form prototypes or physical objects from 3D CAD data is called Rapid prototyping 3D CAD Data Physical objects Rapid Prototyping
- 4. History – how things have changed Decade Importance / Theme 1960s How to do more 1970s -do- & Cheaper 1980s -do- & Better 1990s -do- & Quicker 2000….. -do- & ?????
- 5. Concept First Prototype Multiple Prototype α Protos β- Beta Protos γ-Gamma Prototype Launch Time Line Concept R P T Multiple Prototype α Protos β- Beta Protos γ-Gamma Prototype Launch New Time Line Time Compression thanks to RPT Classical PDC Vs. New PDC Courtesy : Dr. N.Ramani
- 6. Flexibility & Opportunity to improve design quality of a new Product 0% 100% Knowledge / Expertise of our own product ! First Proto α- Proto β -Proto γ -Proto Time 100% 0% (Key Result Area of RPT) Cost of Change ! Quality Paradox Courtesy : Dr. N.Ramani
- 7. Additive manufacturing Vs. Subtractive manufacturing Additive Manufacturing Subtractive manufacturing Technologies that build 3D objects by adding layer-upon-layer of material Technologies that build 3D objects by removing material Eg. – SLS, DMLS, SLA, FDM…. Eg. – CNC Milling
- 8. Different RPT processes 3D Printing Directed Light fabrication Direct-shell production casting Fused deposition modelling Laminated object manufacturing Shape deposition manufacturing Solid ground curing Stereolithography Selective laser sintering Direct metal laser sintering
- 9. Need for RPT • Compress the PDC timeline • Launch the product well ahead of competitors • Design frozen at an earlier stage of PDC • Drawings can easily be released for quotation to tooling vendors • Apt for small Vol. production • Design intricacy is not an issue at all • Speed (Crash test case study) • Acts as a tool between product designers and tooling vendors • Reverse Engineer almost anything
