What is 3D scanning and why is it needed?

To start a project I often will create small maquettes or clay sculptures. To enlarge these using digital processes I use 3D scanning and CNC Milling. I talk about my process quite a bit in my new book 3D Technology In Fine Art and Craft: Exploring 3D Printing, Scanning, Sculpting and Milling. 
Let me enlighten those who are new to my process.


I had a company that came in and scanned John for me. There is a new video of that scan in the previous post. I can't wait to get to work on this. I can do a lot of things int he computer that are harder to do with the real clay. The first thing I did was enlarged the dog.  I'll play with both of these - the dog and John until I get it the way I want it. There is no reason to put a lot of detail in this part, it is proportions I'm after. The detail will come when we get the foam back.

The foam acts as an armature for our clay.  I'm tickled to get started.

Waiting on the scans

I decided to scan John with a different scanner, actually a scanning company that has been working with me on another project will be scanning the small clay figure of John. I'm patiently awaiting the scan of the maquette. I have some things that I want to do on the sculpture in the computer.  After that, it will be sent to my enlarging company where they will enlarge John and his dog in urethan foam.  Here is a video showing the CNC milling on the March Hare for the recent Alice in Wonderland sculpture. It is fascinating to see  how it works.

Once milled the urethane foam of John will be shipped to my Houston studio, where we can begin the wonderful process of bringing the sculpture to life. Meanwhile, we have been dismantling the Alice in Wonderland sculpture so that we can repurpose the clay. You can say that John will have a little Wonderland in him. We now have room for John, and are just waiting on the scanning company. Can't wait to get him here.
