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

Design approach
#DTT17
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
