Sketchbot Prototype Sculpt, Phase Two

As work continues on the sculpt i've learned to NOT over bake Sculpey! However, I did manage to get my carve on and was quite studious in fleshing out the volumes, using two 8" metal files and an X-Acto knife. I then applied a second - and extremely thin - layer of Sculpey, smoothing out as much as possible.  I had to break this into two sessions, as it was getting difficult to keep my detailed work pristine while working on the various parts.  I'll continue on with the bottom half, beefing up the right leg and leveling the character.  The Sharpie paint marker is more for size and thickness reference - i really didn't plan on having him be able to hold other objects other than the customized ones I'll be creating for him.

I've posted more pics up on the Sketchbot Flickr set.

Sketchbot Prototype Sculpt, Phase One

I finally had time on Friday to begin a sculpt of the Sketchbot prototype. In addition to creating a 3d model in the computer, I believe it's equally - if not more - important to execute a traditional sculpt that will allow me to better visualize the forms and volumes, and get a feel for how the object will hold up in real life. Having not actually sculpted since taking a figure sculpting class back in college, I decided to just dive in.

I printed out a size template and used the old cardboard reference trick. I had a pretty good idea how to lay out the underlying armature, however, I think I underestimated the amount of aluminum foil I should have used below the clay layer. I did wrap the thicker wire of the arms and legs with thinner gauged wire so that the Sculpey would have a surface to stick to. (not shown here, once I was rolling I ended up doing less documenting and more sculpting!)

I used an entire(!) box of Super Sculpey just to flesh out the form and ended up baking it longer than instructed because the thickness of the clay was greater than 1/2" at some points. (Next time, I may consider using Styrofoam or balsa wood shaped closer to the actual shape.) The sculpt looked fairly burnt in areas and is rock hard. I hope I'll be able to adequately carve and sandpaper this down a bit. I also need to further explore the "Firm" variant of Super Sculpey that air dries and would most likely have been a better base layer to use. In any case, this first attempt was beneficial in helping me figure out different ways of translating the 2d concept into a 3d form. Stay tuned for more updates!
