As an experiment Titans of CNC, the manufacturer and CNC educational institution, created an isogrid-style skateboard from a 50-pound slab of 6061 aluminum. Resident machinist Barry Setzer started by measuring a standard laminated skateboard deck, transferred the dimensions to Solidworks, then figured out how much material he'd have to remove for the aluminum piece to match the weight of the 3.4-pound laminated one. (In other words, if machined solid, the aluminum deck would weigh 15 pounds, so 11.6 pounds had to go. Enter the isogrid.)
Setzer then ran the design through Mastercam, then CNC-machined it into reality on a BVM 5700 vertical machining center, a high-end machine manufactured by DN Solutions.
Technically speaking, sure, it's not a classic isogrid in that both faces have been removed. But the end result is beautiful:
Impressively, they even machined in the "grip tape" to provide traction for the skater:
Part of the "fun," of course, was working out the hold-down for the milling process: How do you cut the part loose at the end without destroying it? Obviously they figured it out:
