StlWork Contest Entries

In order to show some of the capabilities of StlWork, we held a contest in October and November 2000, and asked the entrants to offer their own creations using StlWork.  Robert Beal won our October contest, with Jeff Demand and Andrew Werby receiving honorable mention. Jeff Demand entered again in November and is the grand prize winner for November. Scroll down to see each one.  Thank-you gentlemen for these efforts. 

Sterling Silver Face Ring.
The electronic model is a repeated section of a full head model which has been distorted and the details exaggerated both for effect and to compensate for detail loss in finishing. The wax was milled on a Unimat SL with the X axis mapped to a rotary table using a 0.6mm twist drill resharpened with a hemispherical end. After milling the  finger hole was bored and the wax parted off on a lathe. The wax model was then investment cast in sterling silver. Once cast the faces were pre polished and then the side bars were soldered on.

The Winner of our Oct. Contest: Robert Beal

"The method was as follows: I found a 3d model on the web. I imported it in to Rhino 3d and modeled the rest of the sign with the ShapeShaver logo in it. I then opened it in STL trans and converted it into a .stl file. I then opened it in STL work and generated all the cutting paths. The actual sign was cut out of 2lb. EPS The cutter is a .5" ball nose with 5" flutes. Cutting depth was 7" total." Robert Beal

Thirteen connected faces milled in wax on a Unimat SL

Honorable mention

 Jeff Demand says his faces were "machined on homemade Unimat SL conversion. The face3.stl file was cropped from one of the Amapi sample files. I scaled it with StlTrans to fit my machine and then used StlWork for rotation and tool path generation. It was milled in machinable wax  using a 1.0mm drill (worked better than end mill specified in .tap file) One sample as milled, the other smoothed and polished." 

Honorable Mention

" I started out with a scallop shell and a plaster casting of some kelp. I scanned these using a Roland MDX-15 touchprobe device, then brought them into Rhino as DXFs, where they were mirrored, tapered,  bent, and assembled. I exported the resulting  form as a binary  STL to STLworks, generated roughing and finish toolpaths, (separating these in Notepad),  then ran them on a MaxNC 10-2 CNC milling machine, using 1/4" and 1/8" ballnose cutting tools."
