I love gyroid infill and tree supports for #3DPrinting. There’s something super cool about how organic/nature-inspired it looks, and it makes me wonder what other kinds of innovations there will be on the purely software side of 3D printing?
“Ironing” or “neosanding” is another one that just seems so smart and purely thought up and implemented in software. Fuzzy sides is another. Just so many ways to utilize the existing hardware in interesting ways!
