ADVANATGES DRAWBACKS
LBM-Very complex internal cavities-Highest precision -lowest roughness
-High energy Thermal Stresses-Slowest Technology
EBM-Kenic energy + Preheating lowerThermal Stresses-Faster than LBM
-Complex internal cavities not possible-Rougher texture and less precise than LBM
LFM/EFM
-Highest speed-Large parts possible with smaller hardware-different materials can be used in thebuild direction
-Rougher texture and less precise than both LBM and EBM-Lack of powder bed limits geometrical complexity-No ability to influence material properties through the layers

Driver Application
Monolithic Construction Reducing the quantity of componentse.g. monolithic burner, 3D dimensional position flexure
Flow Optimization e.g. heat exchangers, laminar manifoldse.g. conformal cooling applications
Miniaturization Very complex high functional parts can fit in very small areae.g. internal cavities with fin structures on the inside of 0,2 mm
Add Functionality Making the geometry more complex to fulfill an additional function will in most cases reduce material and thus cost
Mass reduction Light weight honey comb/lattice structures to reduce weight and optimize strength to weight ratio
First Proto of a MiM-serial ProductionVery small complex products
e.g. Aluminum Housing / Casee.g. fixture/bracket
Design Rules
28/10/2015 Metal Technics 3D 13
1) Avoid Downfacings
Design Rules
28/10/2015 Metal Technics 3D 14
2) Orientation: Accuracy and Roughness
Design Rules
28/10/2015 Metal Technics 3D 15
3) Orientation: Accuracy and Roughness
- X/Y accuracy up to +/-50µm
- Z-direction accuracy up to +/-100µm
- X-Z and Y-Z surfaces have roughness Ra 4-5µm
- X-Y down facing surfaces have roughness Ra 6-7µm
Design Rules
28/10/2015 Metal Technics 3D 16
4) Use material friendly design techniques
Design Rules
28/10/2015 Metal Technics 3D 17
5) Organic Designs:
- Organic designs are more easy to 3D print then designs with straight edges.
- Never work with 90°angles: tension concentrations causing cracks.
Design Rules
28/10/2015 Metal Technics 3D 18
6) Design Checks:
- Down facing surfaces in internal cavities > 45°?
- Channel diameter < Ø 8 mm?
- Sealed cavities?
- Are supports accessible for removal
