In celebration of the Grasshopper beta release for Rhinocerous 3D OSX, (which just came out of beta this past year) I decided to do a quick 2016 remix to try out some selective patterning techniques this time with a voronoi pattern. Blending of surfaces is done in Zbrush by hand masking important details
It prints fine at this scale, but going too much smaller than this size (50x50x50mm) may have spokes that are too thin to print.
I sliced the file with Simplify3D at 0.2mm layer height, 0.4mm nozzle at 55mm/s print 150mm/s travel, no support. Printed in PLA.
Added a generated voronoi intersection on the surface of the object, then made curves from the intersections, and pipes from the curves.
both the density and thickness can be changed independently. other models and surfaces can be intersected that are not voronoi.
The first test involved thickening floating sections to match pipe thicknesses, and only create intersections with voronoi where the remaining surfaces would have been.
model is then taken into brush, where the mesh is recalculated as one with the dynamesh tool. areas are masked off where detail needs to be preserved, and the entire model is smoothed leaving mechanical features intact.
