    I don't think I've ever seen this discussed on Radicons in the year I've been here... but it might warrant interest for those that do casts...

    HydroSpan 100 Enlarging Polymer - YouTube

    It's something called Hydrospan, it's used to make molds that can then be enlarged up to 60% when soaked in water for a couple of days.

    Looked like an interesting idea for TFW folks... based on a thread for using iGear's Rager (a nice Huffer sculpt) as a head for PCC Huffer... but it looked a bit small. This would fix it, no?

    Cool video mate.
    I have seen Radicons use it multiple times with good results. :)

    Interesting, I'd be curious to see someone do that to Kabaya Candy Kits.

    It's been brought up before but I think they made parts with not molds

    If you could make the mold out of it that's pretty awesome.

    The stuff is pretty much out of production or at least it was the last time I looked.

    It was amazing stuff while it lasted.

    It's still listed on a couple of sites:
    The Compleat Sculptor - HydroSpan
    Hydrospan Quart Kit

    Expand-it is also similar: Pink House Studios: Expandit
    as is Panocast-160: PanoCast 160 Increase Casting Size

    I bookmarked Expand-it a while ago, as it seems cheap. Just never had the balls to try it. =) Too short a shelf-life and never had a real need for it.

    Expand-It! I knew there was an alternate product, but I lost the name and couldn't dredge it up from Google to save my life.

    IIRC someone I knew tried ordering from sculpt.com and came up dry even though it's still listed, but that may have changed.

    I've moved on from casting to 3D Printing (and enjoying it MUCH more), so I've not been keeping tabs as much, but other than being a PITA to work with, it's an amazing resource, glad to see it might still be kicking around in one form or another.

    Yeah, it took me a while to find it again (my bookmarks are on my home computer). I know they had Shrink-It but I forgot the company name and had to use a little Google ninja skills to find it.

    HydroSpan is a little 2008 at this point, haha! (Anyone remember this custom?) Shapeways and 3d printers have really made an impact on the scene. I can't wait until 3d printers get around $500 for tabletop solutions (with good resolution, like this). That should cause the customization scene to change tremendously.

    Yup, it was probably a *little* early to bite still, but the 2 grand I dropped on my desktop is undoubtedly the best money I ever spent. SO changed my creative life in the last few months, it's insane :) 

    I can't even imagine how awesome things will be in another 5-10 years.

    I think it'll be the physical-things culture-shift equivalent of the Internet's effect on informaton and computing.

    It seems like you'd have to be at a certain level to pull this off.

    You do. The molding of the hydrospan is difficult. It's the consistency of a gummy bear when expanded, so that makes making a mold harder to do (for 3D parts, if it had a flat or bottom to it, it wouldn't be difficult). And since it will shrink back to it's original size after awhile when exposed to air, it's harder to do a two part mold. The way i've done it is make a one part mold of the hydrospan suspended in the mold box, then make a casting and clean that up to make my master. Lots of molding time, which is why I still haven't finished my project.

    Glad to know that there is other materials out there. I'll have to check that out.

    Randy!

    I agree that 3D printers are the future and are totally kick-ass, but this stuff is more for making an exact duplicate of something that already exists. For the transformer community, 3D models and printing are easier, but then you'd have to recreate parts (or a whole toy) in the computer. It can be done though!
