Make molds with Blue Stuff!

[@JakeStaines]

One other cool thing you can do with this technique is 'float' reinforcing bars on the inside of your parts. For something like that thunder hammer, the haft will be really bendy with green stuff or really brittle with milliput. So just before pressing the two halves of the filled mould together, lay in a length of paperclip or brass rod right down the centre of the haft, it'll come out much more strong and stiff. For bonus points, sculpt some tentacles or cables, cast them in a two-part mould in green stuff with a thin florist's wire reinforcement, and when the putty cures they're basically poseable.

[@TheAll-InNerd]

That’s some solid advice right there JakeStaines! Thanks. 😁

[@adriannaranjo4397]

By far the *best* most in depth video about Blue Stuff. Most don't even show the failures or mention how making a two part mold sorta melts them together, your simple but effective methods really help demonstrate what to do and how to avoid messes

[@TheAll-InNerd]

Glad to hear it helped you out! 😁

[@Chaosmech]

You can also use Sprue Goo (leftover model sprues, cut up into small pieces and melted down with acetone) in these molds, but it's best used for very thin pieces. Otherwise, the acetone collects in one place and gives you big bubble cavities in two-part molds. I never thought of using Lego with Oyumaru to make the molds stay together, that's really smart! I found that one of the best ways to ensure the two parts of the mold could come apart later was to put the first half in the fridge for a while, then heat up the putty for the second half, slap it on, and throw the whole thing in the fridge again. The cold half of the mold resists melting long enough to get it back into the fridge where everything can cool down and the edges don't melt together nearly as much. Then, when it's time to peel them apart, I'd put them in my pocket to get them slightly warm and pull them apart that way. Easy peasy.

[@TheAll-InNerd]

That’s some solid advice man, thank you! 😁

Before pressing part into the Blue Stuff , you should warm it up slightly . Pressing it in cold will cool the blue stuff a bit ,some details will be not as sharp. I mean your molds are great , just another tip worth trying

[@YanniCooper]

Don't heat the blue stuff in a container you're going to eat or drink from ever again, remnants of your epoxy/resin will remain on the blue stuff and can be pretty toxic.

[@Ipsissimus]

I use the leftovers as chewing gum.

This might be another good use of my paint water jars.

i use milliput, and the best application is for bulky bodies (like Cities of Sigmar dwarfs), because you don't risk to lose details or to break them... they give you 20 pair of arms, 20 heads, and 10 bodies: it's my duty to make 20 models

Ive been really wanting to recast bakugan parts with this stuff im finally gonna try it.

[@Alf_Hairy-arse]

One thing I heard (but haven't really tried enough yet to 100% confirm) is to make "gates" on your two part moulds. Pick suitable areas of the bit where it will be easier to clean afterwards and press something like a paper clip in to the mould to create a channel (or channels) comings off of the part. When you press the two parts together, excess putty will hopefully be forced down these channels, rather than squeezing between the two moulds. Hopefully this should reduce mould slipping and give better results.

[@TheAll-InNerd]

That’s a solid advice! Thank you! 😁

[@kaffepuffen8627]

I've been waiting for this! Amazing as always!

[@twincast2005]

I had never thought of a Lego press before. It's ingenious! I usually cast with a 1::1 mix of green stuff and brown stuff in my blue stuff molds. And I've almost never had a use for sprue goo, but now I want to use an Oyumaru cast to make a Milliput mold and try to fill that with sprue goo. It's almost never an issue with recent character models anymore, but I hate mortals going into battle sans helmets, and for the longest time GW sold almost only helmetless character kits, so that was my top priority first use case for casting my own bits, followed by a bunch of pistols for the 2017 edition of Kill Team, and then additional bodies to not let all the extra weapons, heads, and often legs go to waste. And I'm excited for Warhammer: The Old World, very much including all the beautiful returning metal models, but I hate working with metal, and some are infamously top-heavy, to boot, so I'll most likely copy 'em all.

[@retributionangel5078]

You need to use releas Wax when doing double sided molds. Or at least use Kitch Oil like Sunflower Oil. If you do big parts like that TH-Hammer use a peace of Wire and lay it in the middel between 2 smal ammounts of Greenstuff when pressing it into the mold. So you end up with a more resistant Handelpart that doesnt flex or snap as easy.

[@TheAll-InNerd]

you can also mix greenstuff with miliput, first mix them separately then mix them together, it creates a much stronger putty excellent for parts. Another possible solution is epoxy glue, cures after 24 hrs but havent tried it myself, heard it can work.

[@TheAll-InNerd]

I’ve actually tried mixing them both and I had high hopes for the result it but it just didn’t work out for me. I used the Fine milliput then but it just came out as a sticky mess. I have to try it again sometime and use normal Milliput. 😊 Some epoxy can get hot when mixed right? That could be a problem with the blue stuff unless you make the milliput-mold. 😁

[@fraserskomorowski2311]

😂 That outtake. Great job of the methods. Not sure, but maybe isopropyl alcohol would work better to join two bits of milliput. It works well to smooth the stuff while sculpting with it.

silly question does blue stuff or other polymorph thermoplastic melt like other plastic when dipped inside aceton or other chemical that melts it?

[@TheAll-InNerd]

There are no silly questions! However I haven’t tried this but I know that people have used Blue Stuff with ‘sprue goo’ that contains acetone and they seemed to have problems with bubbles. Maybe it’s from the acetone eating into the blue stuff or just the sprue goo being unreliable.

[@kazuhasfriendsupremacy375]

One shop who sells stuff for cosplay and also Blue stuff recommended to me, that if I want to use hot glue gun, I should put the Blue stuff in freezer before I fill it with the glue. What do you think? Could this prevent the Blue Stuff from melting?

Whitemorph is cheaper but not a good alternative... It sticks while soft (When you're putting in the object to cast) and then solidifies without any bend or stretch, so getting your parts or cast parts out is near impossible

[@lart93]

​@@TheAll-InNerd quick question, would you happen to know the approximate temperature of the bluestuff once it's out of the water and soft to mold? I was wondering if I could use a filament enclosure instead of Legos because, well, I don't have any Legos and I can't seem to find any at reasonable prices. And I figured it can't be too hot since you mostly use your fingers to press it down. Let me know if you happen to have a clue, thanks!

[@TheAll-InNerd]

@@lart93 that should work fine as long as you have a few layer lines in the walls of your print. It’s a good idea if you have one size that you’ll use often. You could burn your fingers picking out the pieces when they’re as hot as they can be but not enough to melt plastic. Just maybe soften it a bit if it’s very thin. 😁 Good luck!

[@ginogenero7972]

Will 2-part liquid epoxy resin release after drying when poured into a one-sided Blue Stuff mold? 🤔 Or will the chemical heat cause the Blue Stuff to soften and stick?

[@TheAll-InNerd]

My guess is that the chemical reaction will get too warm and melt the blue stuff. I don’t have that much experience with resin but I know that it’ll get warm when curing.

[@ginogenero7972]

@@TheAll-InNerd Thank you for your quick reply. I suspect you're right even though I have no experience with any of this, outside of construction epoxy, and it gets HOT. 🔥

Resin usually have a chemical reaction when the resin gets heated up and melt the mold. So I wouldn’t recommend using that with blue stuff.

[@XxMazAlmightyxX]

Great video! Definitely going to have to get some of this. Do you know if it reacts to plastic glue? Would sprue goo be a viable option for a cast?

[@TheAll-InNerd]

Since sprue goo has acetone in it I would make a test before doing something bigger. I’ve been trying to suceed with sprue goo myself but all the acetone I’ve tried have seem to be too potent så the plastic never really cures and gets hard again.

[@JakeStaines]

Sprue goo can work for one-part open-faced moulds (and I've never had a problem with the solvents damaging the thermoplastic) bear in mind that it shrinks a lot as it hardens because a high proportion of the volume is the liquid solvent that evaporates out. It's no good for volume casting as it leaves lots of voids as it shrinks. On the plus side it's excellent for copying relief details onto plastic parts as you can line the mould with the goo then press a blank part into it and it hardens pre-welded to the part.

[@ARVETDEG]

Question. Would you recommend me to use a one-sided mold or a double press mold for a sword? It's for a Uruk-Hai mini as sadly it fell, broke and got lost, so I'm missing a sword.

[@TheAll-InNerd]

I would recommend a double press mold. You could use a small piece of a paper clip or a wire in the middle of the mold to get a reinforced sword that hopefully won’t break as easy.

[@ARVETDEG]

@@TheAll-InNerd thanks so much!

I am thinking about using blue stuff to make small molds for hobby concrete. I am not sure of the process.

[@TheAll-InNerd]

Would that be much different than using Green Stuff or Milliput?

@@TheAll-InNerd ​I think so but not sure. The concrete is more fluid so I dont think having the mold in two parts as here would be a good way. And I am not sure if the mold lines will come off nice. I think I need to make the mold like one hollow piece so I can poure the concete down. That will propablly not be ideal for complex miniatures, but it doesnt need to. I have just ordered som blue stuff so I can try it out. Can you recommend some kind of clay to sculp something to make the mold around?

[@TheAll-InNerd]

Maybe some kind of silicone mold would work better then. There’s both a fluid 2 part mix and a clay that you can mix that hardens. The clay could be a bit hard to get your model/part out of tho if it’s deep in it.

Hey man! I've actually tested that out and I really had high hopes for it. I mixed it with 'Fine' milliput and it all just turned too sticky and gooey for my taste. 😅

[@YanniCooper]

For sculpting it can be great, and doesn't have to be 50:50 exactly... More GS will be stickier and give, more rubbery bits when cured, whereas putting in more milliput or Apoxie will give harder more brittle bits. For something with thin and fine details I might go heavier on the GS so the sword or whatever is less likely to break, but a shield doesn't need the flexibility.
