3. 3d Model to Real product 2d Draft  People + Machine
3d Model  CNC + Machine: 3d printing, Machining, Laser cut

4. 3d Printing Add + 더함 Good: Easy, Any shape, Prototype
Poor : Rough, Slow, Material, Property

5. Machining Remove – 뺌 Good: Material, Precision
Poor : Machine able shape, Very slow, Chip loss, Expensive

6. Laser cut Divide – 나눔 Good: All thin 2d shape, Fast, No tool cost
Poor : Expensive equipment, Heat effected

7. Real product to 3d model
3d Scanning: 2d + depth = 3d, Outside surface, Fast / Area
CMM: Precise, Point
CMM :

8. Digital to Mass Production
Digital model
CNC machining
Die and Mold
Die-casting, Forging, Stamping, Plastic injection

9. Summary Industry 4.0 : Digital = Real world
3d model to product : printing, machining, laser cutting [CNC control]
3d model – Mold – Mass production

10. Digital manufacturing
CNC machining: -Remove
3d Printing: +Additive
Metamorphic: ~Forging
