Lots of hype –only a few viable application so far
• AM is not suitable for everything
• Important to know whereto use it
• Case studies are needed to show the way: No morechess pieces!
Case study: AM for joining bicycle tubes
1. Print wax patterns, make mould and cast
2. Print mould and cast
3. Print metal parts directly
4. Composite parts using AM tools
Case 1: AM wax patterns for investment casting
1. CAD/FEA2. Tool design3. Casting simulations4. Making master die5. Casting/Printing patterns6. Creating pattern cluster7. Building up ceramic mould8. De-waxing and sintering9. Making part (casting)10.Breaking mould11.Post-machining
Case 2: AM sand moulds
1. CAD/FEA2. Tool design3. Casting simulations4. Making master die5. Printing patterns6. Creating pattern cluster7. Building up mould8. De-waxing and sintering9. Making part (casting)10.Breaking mould11.Post-machining
Case 3: Direct AM
1. CAD/FEA2. Tool design3. Process simulation/CAM4. Making master die5. Printing patterns6. Creating pattern cluster7. Building up mould8. De-waxing and sintering9. Making part (printing)10.Breaking mould11.Post-machining
Case 4: Composite parts
1. CAD/FEA2. Tool design3. Laminate simulation4. Printing tools5. Surface preparation6. Laminating7. Vacuum bagging8. Finishing
Conclusions
• AM can be used in many ways to achieve thesame goal
• No need to set up a factorySmall companiesenter the market
• Knowing strenghts and weaknesses of AM is crucial for successCase studies are needed
