Supporting structure and slicing
Depending on the predictability of internal structures, these design tools can be further divided into two sub-categories.
If internal volumes are predictable, that is if you have already decided on the shape and geometry of their shells and if you know where you want to add them, cellular structure featured software (i.e., Within Enhance) generates multi-scale features and lattices at acceptably high speed.
If these internal volumes are unpredictable, that is when you have to run programs to locate specifics areas based on structural or functional (or other) requirements, then topology optimisation software are best suited: HyperWorks is a good example.
Both Hypwerworks and WithinEnhance are flexible enough to generate density variations in a single component
