View Full Version : Molding Plastic? (4 a Vandread prop)

Hi! I'm new around here and I hope you can help.
I'm doing Paiway for an upcoming con (I only have 2 weeks to complete this ><) and I'm having problems figuring out how to do her camera.

I've attached a picture of it.

I'd really want to put a real camera inside it and well take pictures but I think that's new possible unless I use foam but then it'll be too soft ><

Thanx in advance for helping. ^_^

You could try carving it out of a few layers of foamcore...which is light but strong. Or gatorboard, which is like foamcore only thicker and stronger.

Do they come in colors like that or do I have to paint them?

You'd have to paint it.

Molding plastic is possible but for a shape like that you'd need to use a vacuumforming table. http://www.studiocreations.com/howto/index.html

Gatorboard? Where can you get Gatorboard? They sell Foamcore at my school, but not Gatorboard..

Thanks so much! ^_^ That website really really helped!

But I'm confused as to what paint I should use after putting the plastic shape? I should also use some glaze at the end to give it that 'plastic glaze' look right?

BTW if I use styrafoam as the cast would it break when I put the plastic over it? I wouldn't want to lug a heavy cast around. ^_^ If styrafoam is not a good idea that can you suggest other materials to use?

styrofoam wouldn't be a good idea because the plastic needs to be hot when you shape it. What pros do is build or carve the shape, then make a negative cast of it, then fill the negative mold with plaster to get a permanent and solid cast. Then they pull the plastic over that.

Enamel (spraypaint) works well on plastic. Acrylic works too, but it can scratch so be careful. Yes, you should probably use some clear spray glaze at the end.

Gatorboard is available at some art supply stores.
