    Default Plastic molding with Blue Stuff

    A cool video I came across on you tube. Useful for duplicating premium gondola or hopper loads. Maybe other stuff.

    It is kind of neat! I suppose if you had a bunch of small detail pieces to make it could prove useful.

    One could generate a prototype via Shapeways, then replicate it in cheaper materials, like say maybe for a tunnel portal - a big enough item that the Shapeways material cost would add up, but you really do need multiple copies.

    A lot of guys in my mecha-customizing groups have always had good things to say about Oyumaru, it's incredible how well it works. Gotta say though this vid made it look so much easier than the guys using resin and pressure pots to make their recasts!

    Wow the guy also has a video on photo etching. It looks tricky but totally something you could do at home.

    Yeah, I think that's why he showed up in my recommended feed. I had posted his etching video here before asking if it could useful for N scale. I haven't ventured into trying it yet, though.

    Great for replacing a missing roof vent for example... Also since it is reusable there is nothing holding you back from making a mold for just 1 copy of something.

    The blue stuff seems out of stock but there is an alternative called "Instant Mold 9001" -- not sure how it compares to the blue stuff.

    The company that makes Alumilite has been selling a blue clay for a real long time.

    Any material that doesn't react to the heat or chemicals in resin casting should do a good job for things you do not want to make a silicone mold of.

    Car modelers have even used aluminum foil for molding flat items. The foil is pressed against the surface and burnished into every crevice. Details as fine as the logo lettering on the sides of cars have been duplicated. If you use a super heavy duty foil the item to be duplicated can be thicker, like a door or car end. If a part can be made with a flat side or in two halves, it can be molded. The foil can duplicate very fine details, if you push it into every nook and cranny. A spray of mold release can help keep the foil from becoming part of the casting.
    Use what you know about the world to model…
    Learn from modeling what you don't know about the real world.

    I searched this "blue stuff" and one guy was using Milliput to make his parts.

    Maybe you can make us a short video. Or at least some pictures and an opinion on it.

    You'll probably be molding box trucks if I had to guess. Haha.

    Also, if you could let us know how long the shipping takes, it would be helpful. Thanks in advance...

    FWIW - it looks like the generic name for this is Oyumaru... looks exactly the same as "Blue Stuff" and Instant Mold...

    I have now used both the Blue Stuff and Oyumaru (http://www.ebay.com/itm/251271738205) -- both seem to be the same and work the same.

    Odd. There aren't any photos of completed projects in this thread. Wonder why that is?
