1. ADDBasics (2015) 3D-Printing Prof. Jouni Partanen Aalto University

2. Gartner Hype Cycle for Emerging Technologies

3. Medical Applications Pre-surgical planning Inert Implants
Salmi M et al., ”Patient specific reconstruction with 3D modeling and DMLS additive manufacturing.” Rapid Prototyping Journal, 18: , 2012.

4. 3D-Printing – objects are made out of slices
Stacking up 2D images you can make 3D objects
Conceptually simple process – great for automation

5. 3D-Printing Technologies – Stereolithography
The mirror steers the laser beam to image one slice of the object
Photocurable polymer
Part moves down
New layer is recoated

6. 3D-Printing (Rapid Prototyping) in Product Development
Commonplace technology since 1990s
Automotive industry
Aerospace
Consumer Products

7. Design for function

8. Aerospace: Boeing

9. New Opportunities – Weight Optimization
In 3D-Printing, complex objects can be made as easily as simple ones – ”complexity comes for free”

10. Dentistry Applications
Invisible teeth aligners

11. 3D-Printing can change the world:
3D-Printing as Production Concept
(10 – 20 year horizon)
Currently 3D-Printing is minute fraction of total production
Global network
Local manufacturing
Fast, cost effective
design change

12. Future Local Spare Part Production
Potentially dramatic reduction of spare part inventories – spare parts are kept in digital form and printed when needed
Electronic delivery to service locations
Spare part printing at home
