3. Fundamentals 3D printing = additive manufacturing Elements
Both used for:
Product development
Production
Elements
3D-data driven
Automated
Add material
No tooling

4. State of the Industry Technology advances Material advances Standards
Diverse landscape
Material advances
Diverse range
Standards
Very few
Adoption
Tiny percentage

5. Where to Start

6. “Unlimited” Possibilities

7. Design for Manufacturability
DFM exists for 3DP
But fewer “rules”
Complications
Rules vary by tech
Rules for post processing
Rules for testing
Adjust for limitations

9. The Process Design for performance Design for time/cost
Clean slate
Design for time/cost
DFM for 3DP
Adjust for tech

12. Adjust for 3D Printing Anisotropism Selected material
Decide orientation
Modify for X, Y and Z load
Selected material
Use design freedoms
Technology limits
Modify features

13. Suggestions Evolution “Play” with design freedoms Use lag to prepare
Low-risk, low-demand apps
Modify/prototype existing
Mental “what ifs”

14. Conclusion Day 1 – when to use Day 2 – materials Day 3 – design
4 pillars
Day 2 – materials
Limited “flavors”
Day 3 – design
Clean slate
Free thinking
With light DFM
