I’ve been interested in Voronoi diagrams for a long time: I really like the organic cellular structure they create.
I ran across a set of pluigins for Maya called SOuP that allow for the ‘shattering’ of 3d mesh via a Voronoi algorithm. I set about to writing a Python script I could apply to any volumetric polygonal solid in Maya to apply this shatter (the by-hand process is over on my Mel Wiki), and this vase was the first usable version I came up with: I modeled the smooth “interior” section of the vase first, and then generated a slightly larger version which I ‘shattered’, and booleaned the two together. It is now a trendy art-piece in my bathroom window. For the pics with the blue-glow, I just dropped a small LED in there .

Note, it is not water-tight: Just for fun I filled it with water: There’s still some sloshing around now inside the print…

• Printed with ‘natural’ PLA on Makerbot Replicator, using “medium” settings in Makerware
• Extruded at 210 deg, HPB off
• 2 shells, 5% infill
• Printed in about 5.5 hours, weights 85g, which works out to $1.91 in filament cost (for a $45 spool).

I had some other experimental prints dealing with Voronoi shattering that led up to this one, which you can see in the below image:

• The print on the far right was my first attempt:  That was 12 hours in, before the printer stopped extruding  But it shows off some of the cool infill patterns and support materials:  It was a little over 3″ cubed, had it finished.
• The print 2nd from the right printed successfully:  I did a full volumetric shatter on another smaller cube.  I duplicated the object in Maya:  One of the objects I did the process where I convert the wireframe to a polygonal solid via blobby-particles.  the other object I strategically deleted different Voronoi chunks, and then merged the two together.  The final version looks like random polygonal volumes held together by spider-webs.
• The remaining prints are unrelated, but make a nice backdrop

I recently ran across a post showing what looked like (to me) “low poly wireframe 3d-printed jewelry”.  Inspired me to try something similar on my Makerbot Replicator.  Half an hour of modeling later in Maya, 51 minutes of printing (PLA), and I came up with the below design.  Just a conceptual prototype of what could be in the future.  I spray-painted it two-tone black\red so that it could be reversible.  My lovely wife graciously let me photograph it on her neck:  Wouldn’t fit on mine

I got it in my head to try a ‘simple bowl’ print, and generated the below model in Maya.  It started out as NURBS, I slapped a lattice on it to get it into the desired shape, then converted it to polys for export.   It’s about 4.5″ wide, 5.75″ deep, and 2.5″ high.

The final product I painted two-tone with spray-paint:  The outer shell is a rubberized spray, I wanted to see how much it would ‘fill in’ the printing ridges.  After four coats, it had just started too.

The inside was sprayed with a bright cherry red.  None of the surfaces were sanded, but I think I’ll try that finishing method on the next one I print.

The whole thing took a bit over seven hours to print on my Makerbot Replicator.
