So what am I doing wrong? The plan was a two-part mold. I used a silicon release spray between the layers, but didn't allow it much time to dry. Would this render it useless, and allow the two sides to bond? Too much spray? Here's another resin figure I made. The mold was stuck with this one too, but I eventually pried it apart. Sculpts not very smooth, the resins full of bubbles, and I don't own an airbrush. It's all fun though!
The first layer definitely needs to be completely cured. Not knowing what kind of silicone you're using I'd say make sure it's a "Universal Mold release". I usually don't let the mold release dry for any certain amount of time and when I think there's enough I give it another good spray, so I doubt there's too much. I've even heard of people using straight vasoline in between layers, just don't get it on the actual piece. That silicone looks pretty hard too... softer silicones are better for 2 parters. BTW, cool sculpts and hand-paint all the way!!!
I was wondering the same. They're all cool, but I'd love to see more pics of the one on the left. Too bad the starfish guy broke. Looks really good.
dude, use silicone RTV ( blue in color) for your mold, it will last forever and is super durable. Make sure youre adding the corect amount of side B to the Silicone, too much can cure it to fast and cause the silicone to get brittle. also, if you want to make a "split" or 2 sided mold, use playdo , it can be removed from your sculpt pretty easy.
Cliff, Lokash, thanks for the help. So play-doh is good? first sculpt I did was with paperclay, embedding it in ceramic clay to make the mold. Unfortunately the moisture of the clay reactivated it. Next sculpt was wax, and I used an oil-based clay.... same problem Now it's supersculpey with the oil-based clay, that sticks too but is managable. I'll try and hunt out the japanese equivalent of the play-doh for the next attempt. Jcrazy, melek_taus, here's the other figure in his half-finished state. I was working with wax, but the texture combined with waxes malleability was just too much for my current skill level. I do like it, so will try again in sculpey.
I use this green "clay" sold at Tokyu Hands for my two part molds, and it seems to work well. It has the texture of playdoh. I don't have the packaging, and can't remember the name, but it comes in a big block with the other clay, and has yellow lettering.
These guys are so great! I have used the smooth on stuff before. The molds are real sorft and easy to handle.
I mean to say to use playdo for the first half that you submerge your sculpt in when doing a 2 part mold.
Don't worry, I understood that. I'll be hitting up Tokyu Hands this weekend for new supplies. I'll post some pictures again if things work out this time.
Yodobashi and Sakuraya have some decent oil-free clays that are good for making bases for latex molds. I also use Vaseline between layers and I haven't had any problems splitting them. Oh yeah, and don't forget to key your halves (i.e. make indentations in one side so the two halves will fit together well). Your sculpting is looking good! Love the starfish guy!!!
thanks for all the kind words, and to all the people who helped me out. This time around I went with the Vaseline, or Waselin as they call it in Japan. Worked perfectly! Now to buy something to paint it with.
Those look awesome. Like Cliff said...Universal Mold Release and sulphur-free clay. Use a brush to spread the release and then spray another layer on everything. Also sealing your clay helps. +1 on the Smooth On products.
The ol' rub technique in action. It really does a good job showing off all the imperfections in the mold...but whatever, He's a starfish controlled mutated zombie- a little battle damage is to be expected.
