[Thomas] does a lot of interesting experiments with 3D printing and lately, he’s been using the free version of Fusion 360 to do topology optimization. He started with a blocky bookshelf bracket and let the software analyze the loads so it can remove pieces that don’t contribute a lot to the bracket’s strength. This uses less material, prints faster, and — [Thomas’] biggest goal — looks cool.
If you know [Thomas] you know he didn’t just hope the brackets would be strong enough. He made prototypes and destroyed them in testing. Despite being printed in a poor orientation for strength, the models held a good bit of weight.
