ADVANATGES DRAWBACKS
LBM
-Very complex internal cavities
-Highest precision
-lowest roughness
-High energy Thermal Stresses
-Slowest Technology
EBM
-Kenic energy + Preheating lower
Thermal 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 the
build 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

12. Potential
28/10/2015 Metal Technics 3D 12
Driver Application
Monolithic Construction Reducing the quantity of components
e.g. monolithic burner, 3D dimensional position flexure
Flow Optimization e.g. heat exchangers, laminar manifolds
e.g. conformal cooling applications
Miniaturization Very complex high functional parts can fit in very small area
e.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 Production
Very small complex products
e.g. Aluminum Housing / Case
e.g. fixture/bracket
15. 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
17. 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.
18. 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
