Silent Stepper Drivers & Topology Optimization

Stefan will soon be on a 3 week holiday trip to Japan and talks about his preparations in terms of camera equipment and Tom presents his latest 10-25mm f1.7 lens he recently bought. Both discuss if YouTube is a suitable platform for their podcast and if they should release their show as audio-only. Stefan made a discovery how STL files can become inaccurate if they are exported in the wrong coordinate system. Both talk in depth about the meaningfulness of topology optimization and lattice structure. Since Stefan recently received a Cetus3D Mk3 and is annoyed by it's noise he asks Tom to explain if implementing silent stepper drivers is hard and expensive and why they didn't become a standard in current-gen 3D printers.
