3 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

13 Topology Optimization 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 Shape Generator Shape Optimization

14 Topology Optimization - Shape Generator Optimizes the weight of a part based on: Given shape Forces Restricted areas Material Note: Optimized for stiffness therfore it doesn t matter if you put 1N or 100kN on the part. You ALWAYS need to validate the stress afterwards

15 Topology Optimization Shape Generator 4.1kg 0,1mm displacement 9kg 0,061mm displacement 7,3kg 0,074mm displacement Given Shape Optimized Shape Parametric

16 Topology Optimization Lattice Structures Replacing material by a dynamic lattice structure Predefined lattices X, W, Bone,.. Define custom lattices 6,7Kg 0,09 mm displacement Optimize lattices based on forces and pressure
