Comment on Shape optimized spoolholder
IMALlama@lemmy.world 6 months agoVery cool!
Evidently nastran is headless. Did you use a GUI wrapper/interface? If yes, which one?
Final question: is this object the typical x wall thickness and y infill part? Did you happen to check the weight of a solid and optimized part? There’s no doubt in my mind that this would save mass if it was a solid part, but if it’s fairly hollow I wonder if the extra walls actually resulted in a heavier part.

Inventor has a GUI for it. There are more options.
A slightly higher wall count for prints and the weight of the unoptimized solid is pointless in this instance as it starts with a larger slab and tell it to remove x% of weight. With the simulation result you either increase or decrease the x% removed setting and run it again till the load part strength is correct. Very basic in this regard but this was a quick design. How the spool is relative to the mounting points isn’t optimized. It was just me drawing something.
This particular part is 70g each with the filament being approx. 100mm moved forward (leaver length) and were simulated to withstand roughly 12kg and tested with 5.5kg+spool weights.
