Beginner Sculpt, Mold and Cast with photos Begins Batarangs


I picked up a ton of materials from Monster Makers a few years ago to start making my own Halloween masks. After spending a long time on my monster mask sculpt, I was always afraid to go to the molding phase and risk losing my clay sculpt. So for a couple years, I just let the sculpture sit there in clay form, not quite finished.

After joining this board, and reading hundreds of threads and years worth of posts, my creativity, interest and desire to keep working and experiment with all the material I have laying around was peaked.

So last week I decided to just throw together a quick little sculpt of a Batman symbol, similar to the Begins batarang, and then take it through the whole process to get a feel for it.

1.) Sculpted the symbol with MonsterMakers oil based clay.

2.) Clear coated and built a mold box with cardboard and duct tape.

3.) Poured UltraCal

4.) Removed mold, pulled out clay (cleaned up further after this pic was taken.)

5.) Poured latex, let cure

6.) Pulled latex, carefully brushed light powder on, then filled with stupid latex foam sealant (just for fun, but didn't work as I hoped.)

7.) A few coats of Plasti-dip. Needs to be trimmed around the edges. (I think I pulled a little early maybe, as it created an ugly fold on the front of the bat as you can see.)

Overall, it was a fun little experiment, and didn't take much time or effort. I learned that plain cardboard isn't good as mold walls, since it absorbed a lot of moisture and was mushy when I removed it. Also determined the latex foam sealant stuff is no good for what I hoped, won't use that again. And learned a lot about general timing and the properties of these materials.

I cast another latex copy a little thicker and let it cure longer yesterday, and it came out looking really nice. I'll plasti-dip it tonight.

This is pretty basic, and not that good, but I noticed several other beginners had been asking questions and posting about molding and whatnot, so I figured it might be fun to share my experience on something real easy.

That's cool,but what you really want for something like this is a silicone mold.

Sculpt it like you did and clear coat it.
Then,instead of ultra-cal(which is good for latex),you use RTV silicone.

Now your clay piece will come right out of the mold,and probably completely in tact.
Then just clean the mold,and now it's ready for resin pulls.
You can also do hard shore urethane pulls as well.

Thanks, yeah I ordered a small kit of silicon products to test with.

This was really just a test product to get used to ultracal and latex since I have a lot of it. And I figured it would be fun to have little soft rubber batarangs that can be tossed around without damaging anything. :)

For the real thing, I'll sculpt a better quality batarang and spend more time cleaning it up, then definitely do silicone with resin castings.

Since I eventually want to finish up my monster Halloween mask, I figured it would be good to at least test the ultra-cal and latex before doing the whole mask.

Of course, after reading about doing jacket molds, I might be better off doing that for the full mask. Honestly, I'd love for the final mask to be in silicone, so I'm still not completely ready until I figure out exactly what I need.

Here's a few pics of the Monster sculpt as it sits right now. Still needs smoothing and skin texturing tweaked though.

The middle of the mouth between the tusks will eventually be open to the wearer's face, worn similar to a cowl. Then the wearer (me) will have custom dentures and makeup to blend in with the inside of the monster's mouth. Kind of a mouth-within-a-mouth effect.

I'm a bit concerned with undercuts around the mouth area and lips though, so I'm still tweaking that.

dude that sculpt looks great, and even though your rang didn't turn out you still learnt some important lessons.

awsome work dude. :up
