I'm going to show you guys how to turn almost any 3d shape you have into a real object. I used a regular hot wire cnc. The hot wire cnc is that computer controlled machine that cuts letters out of eps or xps foam. I actually saw an instructable on this site about making a cheap hot wire cnc. Adding a turning table to a foam cutter cnc allows you to make any round shape like columns, vases, spheres, eggs. I'm going to show you how you can create complexe shapes using a turning table. My goal was to make two pieces of 3 meters Anubis. Anubis was a god in egiptian culture with human body and jackal head. I didn't make the 3d figure, I actually found it for free on the internet so I'm only showing you the technique I used to convert a 3d shape into a real life object.
Please vote my instructable in the "Make it real challange"... Thanks
Step 1: Cut your 3d shape to make it fit in your hot wire cnc
The first thing I did was to cut the 3d object in smaller pieces for two reasons: 1. it had to fit in my foam cutter cnc (that is 60 cm high); 2. I only needed the left half of the body for the next process, because, you'll see in a minute that I easily mirrored it.
Step 2: Rotate and render the 3d object using only paralel projection
Very important in this next process is to use "paralel projection" instead of regular "perspective" camera. The next step was to take each and every object piece, rotate it, and render it after each rotation. The program I used had a rotation tool that allowed me to rotate it by 15 degrees. So I rotate every piece 12 times clockwise and made images of it.
