Motivation
 Metal additive
manufacturing is quickly
becoming an interesting and
viable business solution
 New approaches to
component design are
necessary to sufficiently
take advantage of the
geometric freedom that AM
allows

Benefit
more
from AM
Systematic
concept
design
Minimize
use of
material
New
functionality
Minimize
post-
processing
Optimize: topology, shape,
size
Take advantage of
geometric freedom
• Lattice structures
• Internal channels
• Internal cavities
• Part consolidation
• Optimize print orientation
• Self-supporting shapes
Simulation based design Properties of a
successful AM
product
• New functionality
• Lightweight, compact
• Short build time
• Single consolidated
part
• No assembly needed
• Minimal machining &
finishing
