    i know some of you have talked to me before about casting in colors, and i have used black dye, but i dont know how to get a silver color.

    i know i could mix white and black and make a grey color, but i was wondering if you could get a metallic dye to use, also can you mix different brands of dyes with different resins?

    I don't think there are metallic dyes or that it's even possible. Metallics, I believe, actually have metal in them and have to be applied uniformly to get a metallic look. Otherwise I have a feeling you'd get swirls. Anyway, just guessing on my part from the lack of any resin metallic dyes anywhere I've looked.

    Depends...if your using smooth on just don't use as much black.

    I'd personally go black then get a spray chrome over the cast. I also do recall that "silver" and "Gold" dyed plastics are pretty weak.

    I found some rust oleum silver spray at meijers (store like wal mart). Probably not like the best stuff out there but I bet it does a decent enough job to do as good as a silver dye.

    I'll do a test with it after the raining stops and post a pic if you'd like.

    I will ask my buddy what it's called, but to get a metal look it's actually a powder you put into the inside walls of the mold. once you pour it in the resin infuses to the powder and you have a metallic sheen to it. if you cut into it the inside would be the cast color, it's only on the surface, so no weakening of the resin. Fishdirt is right in that you'd get swirls if you mixed it into the resin. I haven't actually done this yet, but we've talked about it for an upcoming project where we're going to cast parts to look like bronze and copper.

    But painting it later is the easiest and cheapest way to get the look you want. I wouldn't try this copper thing I mentioned if my friend hadn't done it succesfully before.

    R!

    Shapeways do that sorta thing, they call it alumide.



    They also say that it makes the mold much weaker, so be careful with your ratios!

    For my silver casted parts, I use the Smooth On metallic powders. Just brush it on, remove any excess, then pour in the resin. I give my pieces a clear coat, to help protect the look. But it doesn't seem to be really needed, as the resin bonds with the powder well. Smooth on has a bunch of metallic powders besides silver and gold. And you can get some interesting looks, compared to which color resins you use along with which powder.

    Another thing you could try, is spray painting silver paint onto the mold first. Once its completely dry, pour in the resin, and it'll bond to the paint. I've tried it once, and got a mixed result.

    About Master Blaster's point: Alumide is WSF with aluminium powder mixed in, and hence is stronger but less flexible. But it's NOT metallic, not even close. It's really very obvious that it has speckles of silver 'dust', but it's nowhere near a metallic silver.

    Just my 2 cents, though i'm pretty sure anyone who's ever printed in Alumide would agree it's far from metallic silver. At best, with a stretch of the imagination, you could pass it off as 'metallic' gray. At best.

    Well I used the rust oleum silver. It made an almost perfect match to hasbro paint silver. Definitely silver but a dullish silver (like onslaughts shoulders from the universe line). I am waiting for a good cure before I hit it with the buffer. It'll work for me on a few things and is a ton cheaper then tiny bottles of hobby paint chrome I get.

    haha no. That's someone else.

    This is the rustoleum paint on top of black fusion(the cup) and white plastic fork. Pretty quick and easy. Little fusion on top and polish and it might look shiny (I'll do this shortly ).

    yep, almost a perfect match to Hasbro silver. It was only about 4 dollars for a big spray can.
