Was bedeutet „Additive Fertigung“?
Definition (Wikipedia):
3D printing, also known as additive manufacturing (AM), refers to processes used to
create a three-dimensional object in which successive layers of material are formed
under computer control to create an object. Objects can be of almost any shape or
geometry and are produced using digital model data from a 3D model

Primary Use Cases:
• Lightweight existing designs/concept
• Conceptual design development
Functionality:
• Mass target with maximum stiffness
• Minimum member size
• Multiple load cases
• Single part of an assembly
• Promote mesh to design
Topology Optimization
Shape Generator Shape Optimization
Optimizes the weight of a part based on:
▪ Given shape
▪ Forces
▪ Restricted areas
▪ Material
Topology Optimization - “Shape Generator”
Note:
Optimized for stiffness therfore itdoesn‘t matter if you put 1N or 100kN on the part. You ALWAYS need tovalidate the stress afterwards
Topology Optimization “Shape Generator”
„Given“ Shape Optimized Shape Parametric Design
7,3kg0,074mm displacement
9kg0,061mm displacement
4.1kg0,1mm displacement
Replacing material by a
dynamic lattice structure
▪ Predefined lattices
▪ „X“, „W“, „Bone“, ..
▪ Define custom lattices
▪ Optimize lattices based
on forces and pressure
Topology Optimization “Lattice Structures”
6,7Kg0,09 mm displacement
Optimize the Topology Using Lattices

Due to internal stress part structure may collapse during print or post
processing
▪ Identify issues before
printing
▪ Simulate internal stress
▪ Simulate deformation
▪ Simulate delamination
