I would like to produce a tough print that can support weight and I’m interested to learn about FEM/FAI applications, which allow users to import STL designs and optimise internal lattices and skins for light-weighting, stiffness or flexibility. I have read about a new AutoCAD product called ‘Within’ <goo.gl/RheCg7> that allows users to import STL designs and optimize internal lattices and skins for lightweighting, stiffness or flexibility. However, the software is not available as a demo, or for purchase. I’m trying Z88 Aurora <en.z88.de>, but am finding the learning curve steep and am not sure how well suited it is for conventional 3D printing. Does anyone here have experience with this type of optimisation software and how to apply it for printing with Lulzbot printers (TAZ 5, in my case).
Grateful for help.
