8. Agreed categories 1. VAT Photopolymerisation 2. Sheet Lamination
3. Material Extrusion
4. Material Jetting
5. Powder Bed Fusion (PBF)
6. Binder Jetting
7. Directed Energy Deposition (DED)

13. Laser Powder Bed Fusion L-PBF
Fatigue life is worse.
Yield strength can be better
Hot Isostatic pressing (HIP) can improve fatigue life but reduces yield strength
HIP can improve density but has to start high with no linked porosity

14. Costs £6.18/cm3 for L-PBF (But full machine)
Recent stainless steel 316L £18.30/cm3

16. Powder 1/3 cost is raw powder Powder characteristics affect build
Particle size and distribution
Particle shape
Particle porosity
Bulk packing and Flow
Alloy composition
Interstitials
Cleanliness

17. Gas
