Lamenter Posted February 9, 2010 Share Posted February 9, 2010 A simple tutorial for using Silicone Putty as a mold for greenstuff castings (ie: small details rather than whole models). Silicone putty is great for this because it's extremely fast setting (about a minute), captures detail really well and greenstuff won't stick to it at all. In this example I made a very long purity seal from greenstuff (it'll be used on my Grey Knight conversions), sculpting it on a piece of plasticard. So here I sculpted a long flowing seal onto a piece of plasticard. http://www.masteroftheforge.com/files/images/siliconetutorial/purityseal.jpg The silicone putty comes in two parts, both of which are of, well a putty consistency (obviously). http://www.masteroftheforge.com/files/images/siliconetutorial/sp1.jpg Take two small equal sized amounts. They are very easily mixed just using fingertips and takes probably no more than 20-30 seconds. It's not exactly messy, but you'll want to wash your hands afterwards. http://www.masteroftheforge.com/files/images/siliconetutorial/sp2.jpg It hardens very quickly, so as soon as it's mixed into one colour, press it onto whatever it is you are molding, being careful to sort of spread it over the piece so as not to capture air bubbles. http://www.masteroftheforge.com/files/images/siliconetutorial/sp3.jpg Give it a minute to set, and pull it off. It captures details very nicely (you can see my fingerprints on the putty in the photo above). Whilst normally on larger objects the mold has some flexibility, on small pieces like this there really is none. It's very easy to cut and will break if you use too much force, but the beauty of this material is that Greenstuff will not stick to it at all, so there's no need for any kind of release agent. http://www.masteroftheforge.com/files/images/siliconetutorial/sp4.jpg When making the cast a soft mix of greenstuff is highly recommended (ie: at least twice as much yellow as blue) and you'll need to press it into the mold with a wet (and preferably rubber) tool, otherwise it'll stick to the tool and be pulled right out of the mold. Pretty simple to use and easily found in online stores or on ebay. I paid about £20/$30 for 500g but most people won't need this much unless molding a lot of stuff.

wizard12 Posted February 9, 2010 Share Posted February 9, 2010 nice, I thought of learning how to cast resin to make greenstuff molds but this is far better. Link to comment Share on other sites More sharing options...
ShotgunFacelift Posted February 11, 2010 Share Posted February 11, 2010 How long is the drying time on this kind of epoxy? I found a vendor here who sells it in bulk and I'm wondering if its feasible to use this as a GS replacement. Link to comment Share on other sites More sharing options...

It retains flexibility, so it would make an absolutely terrible Greenstuff replacement. It's for making molds. Link to comment Share on other sites More sharing options...

Grand Master Tchezzarus Posted February 14, 2010 Share Posted February 14, 2010 Could you give some name/brand of this product, so I could try to find some back home. Thanks, Tchezz. Link to comment Share on other sites More sharing options...

There's no brand name on the pots. I got mine from ebay (search silicone putty). EDIT:now available from blu-stuff.com Link to comment Share on other sites More sharing options...
Tyron Posted February 15, 2010 Share Posted February 15, 2010 Is this stuff good to make molds for whole models? And if not can you link to something that does please? :pinch: Link to comment Share on other sites More sharing options...
Lamenter Posted February 16, 2010 Author Share Posted February 16, 2010 Is this stuff good to make molds for whole models? And if not can you link to something that does please? :D no not really. The small size if the molds means there isn't enough flexibilty and also the drying/curing time is so quick it's not possible to really work on cleaning up the shape of the mold. For molding whole figures I'd suggest silicone rubber which starts as a two part liquid. There are lots of guides out there on how to use this stuff, though I'll post my results when I make my own casts soon enough. Link to comment Share on other sites More sharing options...
Beornric Posted February 17, 2010 Share Posted February 17, 2010 Thanks for this I hadn't thought this stuff would be a good idea, but I can see it has it's uses now. Here is a company that sells the silicone you were asking about Tyron: http://www.mouldlife.co.uk/?pageid=prodshow&prodid=300 Link to comment Share on other sites More sharing options...

Lamenter Posted March 4, 2010 Author Share Posted March 4, 2010 How can we make a mould of say, an MK8 chestplate? Certainly something that would require a two piece mold. I'll try and do a tutorial when I start casting my own components. Link to comment Share on other sites More sharing options...
Lestat Posted March 4, 2010 Share Posted March 4, 2010 Is silicone putty the same as the stuff dentists use for taking molds of teeth? From the pics, it kind of looks like the stuff you use to affix fake fangs at Halloween (the vampire fangs that fit like caps over your own teeth) Link to comment Share on other sites More sharing options...
templarboy Posted March 24, 2010 Share Posted March 24, 2010 Could resin be poured into this mould? Is the silicon flexible? Flexibility would make pressing the green stuff into the mould more difficult wouldn't it? Very cool regardless! Link to comment Share on other sites More sharing options...

I see no reason you couldn't use resin, but there's no flexibility in molds on the such a small scale. Link to comment Share on other sites More sharing options...

The Damned Posted March 30, 2010 Share Posted March 30, 2010 I've been trying to make greenstuff molds of my old metal legion of the damned shoulder pads and haven't had any luck. Do you think the silicone would be a bit better for this? Would it stick to the metal shoulder pads if I skipped the greenstuff part? Thanks for the tutorial!

The Nameless Posted May 26, 2011 Share Posted May 26, 2011 As The Damned has mentioned, my green-stuff molds have really been failing me and i think this is an amazing idea that will really make awesome molds, thanks Lamenter! Link to comment Share on other sites More sharing options...
