Thanks for sharing!

Nice modeling techniques, but I'm not sure there would be any advantage to trying to 3d print it. If using liquid resin 3d printing (e.g. stereolithography or DLP) or laser-sintering of dry powder, you'd have to create drain holes and vent holes to get the uncured material out, then plug the two vent holes, which would require a lot of manual intervention to drain it out. In addition, stereolithography systems already have a mode to create an outer skin with interior lattice and the necessary drain holes, a process 3D Systems patented decades ago called "Quickcast". If using FDM (fused deposition modeling), those 3d printing systems already build all of their parts with a watertight outer skin and a lattice type core, and their lattice core is optimized to reduce material consumption while adequately supporting the top surfaces of the outer skin.. I could see 3d printing the Implicit Modeling version without an outer skin, preferably via stereolithography or laser sintering, but so far I just can't see using NX's Implicit Modeling for the interior lattice of an enclosed part.
