2. History
Chuck Hull, Founder 3D Systems
Inventor of 3D Printing
1st 3D Printed Part: eye-wash
1984 - Stereolithography
1984 – Stereolithography (SLA)
1989 – Selective Laser Sintering (SLS)
1991 – Fused Deposition Modeling (FDM)
2001 - First desktop 3D Printer

3. Materials
Many many kinds of polymers
Steel, Aluminum, etc
Titanium Chocolate!
Multi-colored PLA filaments Sugar, etc!
Plastics Metals Foodstuff

4. Hershey’s Chocolate Printer

5. Overview of Techs
Type Technologies Materials
Extrusion Fused deposition modeling (FDM)
Any material that can transition from solid to
liquid and back to solid
Wire Electron Beam Freeform Fabrication (EBF3) Almost any metal alloy
Granular
Direct metal laser sintering (DMLS) Almost any metal alloy
Selective laser melting (SLM)
Titanium alloys, Cobalt Chrome alloys,
Stainless Steel, Aluminium
Selective laser sintering (SLS)
Thermoplastics, metal powders, ceramic
powders
Laminated Laminated object manufacturing (LOM) Paper, metal foil, plastic film
Light
polymerisation
Stereolithography (SLA)
curable liquid photopolymerDigital Light Processing (DLP)
Inkjet/Polyjet

6. So how do all these techs work?
Many different types of 3D Printing, but in essence they all
“add” material layer by layer. Thus: Additive
Manufacturing.

7. Subtractive Manufacturing
•Material = Free (or Cheap)
•Geometry/Shape = $$$
•Lot size dependent
•Fast(er)
•Design for Manufacturing
Additive Manufacturing
•Material = $$$
•Geometry/Shape = Free
•Lot size independent
•Slow (today) 4-10 mm/hr
•Manufacturing for Design
The Additive Manufacturing Advantage

9. 3D Printing at It's Best
•Material = $$$
•Geometry/Complexity = Free
•Manufacturing for Design
→Minimize material: Hollow
→Crazy geometry: no problem
→No compromises on design

12. Rapid Iteration & Prototyping
Extremely quick turn iterations allow for visualization, testing and feedback

13. Design Evolution & Optimization
FEA Structural Optimization Software for weight reduction.

14. Biomimicry
Extremely strong and lightweight structures
Bone structures, shell structures, honeycomb, organic trusses, etc

15. Part Consolidation
Fewer parts = less failure points, less assembly, less cost
Extremely complex assemblies reduced to single components
