HOW GOOD is Molding and Casting with "Blue Stuff"?...

[@douglasfree1664]

I suggest making a Lego frame to make neat square molds.

[@undeadch1cken523]

Agreed Lego is ideal for this

[@p1xelspaceship997]

That's a great idea I'ma have to try this

[@danlotroth9231]

Any frame at all. Plus talc on the edges of the molds to help releases from the cast.

[@timomatic6226]

Can confirm. I do the same, and it works faaaaar better. Also the amount of putty you put in makes or breaks the result. Also pressure. You can try using rubber bands or clamps to keep pressure on the blue stuff. But both the right amount used in both cases is definately a learning curve.

[@thescourge286]

Yes to everything here, i do the same on a small lego sheet, make a frame i even layed the smooth lego parts on it so it doesnt get those lego tabs/bumps in my Oyumaru/blue stuff molds.

[@andrewharris2087]

50 50 miliput greenstuff mix, and clean the excess off the mould before pressing together. Cast in a small lego box for no mould expansion when casting the original piece.

[@thelobsterclause9010]

From what I remember watching tutorials with this stuff, the secret to 2 stuff molds is to use toothpicks to provide channels for the extra material to go out of when you squish the two halves together

[@mikaelpeterson6567]

I second this. I've been using bluestuff for over a year now and have replicated a squad of Primaris marines amongst loads of other things. Channels out of pipe/rods that you remove before the actual casting makes all the difference and avoids like 90% of all flash.

[@zramirez5471]

Couple things: 1) No free form molds - either build a frame or use dowels, but you need a single piece mold that you can cut in half so that the alignment is maintained. 2) MOLD RELEASE AGENT - vaseline or something similar that won't interact with your part medium. 3) Liquids are easier that solids; solid material will frequently require relief cuts/holes in the mold for air to escape to avoid bubbles and imperfections, but for liquids like resin you may have to hit it with a heat gun to eliminate bubbles. In order to best reproduce GW parts, you would really need to make a mold of the whole sprue and use a spin-down style mold impregnation; all the hard stuff is done for you that way. Die making is a pretty insane art of its own.

[@13legomania]

If you don't mind my replying on an 8 month old comment what do you mean by "spin down style mold impregnation"?

[@blairbird8022]

I was half expecting a Goobertown Hobbies insert with Brent explaining why the plastics stuck together.

[@IvantheMenite]

Make a small mold case for the blue stuff before pressing the part in. I use plastic card or popsicle sticks. This helps with keeping a consistent thickness beneath the part as well as controlling the amount of blue stuff you use. A 2 part mold needs registration marks for the 2 halves to meet together the same way each time.

[@ivandeoz]

yep, i do the same, but for the casing i use legos. also i use something flat and sturdy, like more legos, to pres the second part of the mold more even.

[@teagancombest6049]

Also make sure your bottom half is completely cooled before making the top half or you will trap your piece in the mold and ruin it.

[@stoffhimel]

if you want to cast something like the wings, get some casting silicone. make a 2 piece mold, and measure out how much casting material you'll need. with sufficient pressure on both sides of the mold, you'll only have to do minor cleanup.

[@fjalarhenriksson]

yeah thats what i intend to do on larget flatter pieces like the tracks sides on a leman russ. smaller parts can be done this way but for large flat ones the bluestuff will not work

[@B1-997]

i think to help figure out how much material you need, weigh the piece you're using then get the same weight of material you want to use?

From the small amount I know about UV resin I think your problems with it's curing might have come from the blue stuff mold's blue color. The color and opacity of the mold can affect how evenly and easily the UV light reaches the resin. This can cause some areas to cure unevenly or take forever to cure if the mold is absorbing or blocking a significant amount of UV light.

[@TommyWashow]

this is likely correct cause the UV flashlights that are sold arent true UV and dip a bit into the blue usually 405nm for curing resins and UV is everything lower than 400nm so the blue stuff probably likes the blue light or something im no scientist wheres brent

[@invaderzim1964]

Resin 3d printers use photo resin but cure in layers that are fractions of mm. I would suggest trying adding a little, cure, repeat. This way the entire thing would be cured throughout

[@Allan_Lugia]

I´ve tried using a 2part bluestuff form shining Uv-light though.. epic fail.. can i get bluestuff? but without the blue?

[@OngoGablogian666]

@@Allan_Lugia I used "Oyumaru" with UV resin and it worked well. Just the smell was cancer to me and a few bubbles from the reaction being too fast. In the end i decided transparent silicone moulds may be best with UV resin because the moulds were more precise and less likely to be deformed.

[@LeftOfToday]

A trick that might apply to this is to stick the resin/mold into a clear or metal bowl filled with water after the initial curing. I use a silver pet dish (super cheap) for the reflective properties and it's helped in some cases where the resin didn't want to harden.

[@peterrobson9920]

One great medium for making recasts is your old sprues..simply soak in acetone and once soft use them,they take a while to set but once they do they work a treat

@@ThatGuy-eu2vt I get that, but tbh I have no interest in buying second hand unless everything is still unpainted and on the sprue. I play a lot of Warhammer video games, got all the DoW games/addons but 3 as well as TWW1+2 plus most of the dlc. But as for tabletop.... I don't really have any interest in the game itself. But building minis, converting painting, crafting etc... That appeals to me. I'd rather start from scratch than try and make something out of someone elses botched attempts. Don't want to deal with stripping paint, broken minis or any of the multitude problems you deal with second hand. That being said, I have seen job lots for bits on ebay that would be worth buying. And a 3D printer IS within my price range, especially when you compare it to the long term cost of buying from GW.

[@kookieslayer]

I found that type of molding putty is great for 1 sided stuff like shields or duplicating resin bases. Making a good 2 sided mold requires a lot more practice. I would highly suggest using some beads or something around the part to make indents that are easy to use to allign both halves of the mold. I t's still hard to get good results because the putty is still flexible when cooled down. So when you push your halves together it deforms the inprint...

[@teagancombest6049]

That's why you use a mold case. The plastic cap to a bottle works pretty well, or you can make one, that will hold the bottom half of the mold stable while you press them together. Also make sure you have made registration marks in the bottom half before molding the top half so that it goes on in the correct orientation and stays there. I copied some horns from Rotigus and they came out pretty good on my first try. It is better for more organic shapes than like armor or thjngs that need to be clean and exact.

[@hmmm348]

Referred to this channel by a friend. I liked your realistic expectations, given recasting would require a lot of trial and error/experience for everyone in the beginning. Just sets a good standard for beginners and doesn't leave us feeling like we're going to be attempting the impossible.

[@alejandroacevedo2521]

[@richardmcadams3493]

I use sculpting tools to push epoxy into the mold details then bulk out the main body of the piece. I like apoxie sculpt because you can use isopropyl alcohol to brush away the excess flash or to thin it significantly before putting the two halves of the mold together

[@Telmach]

I've dabbled with recasting. I've found success with two part silicon molds. I use a lego box frame and press an even layer of plasticine clay into it. I then press the model on it's sprue or custom venting into the clay up to the part's mold line, and poke keying holes in the corners and voids. I mix up silicon and pour from a height in one corner of the mold box. Once it has set, I disassemble, leaving the model in the silicon, but cleaning all the clay off. Then you just flip it over, rebuild the box, dust the silicon with very small amount of talcum powder, the pour another batch of silicon over it to make the other half. Important note, you will think that you screwed up and didn't put enough talc and the mold fully bonded. Which yes that might be the case, but also even if you did everything right, the mold will still be challenging to separate. Your forearms will be burning by the time you get your sprue out. If you do it often enough, you'll start to look like a gorilla, it's good fun.

[@jr3nton]

its amazing for wall pieces or taking reliefs off sector mechanicus to build buildings, for really detailed stuff use gsw acrylic resin to pour into your moulds (:

also start from the middle of what you want and press outwards so you don't get bubbles press mould over the top of what you want.

I imagine multiple thinner layers of UV resin would work great, build it up over three or four pours.

[@ZeonZz-Swe]

You could always warm the blue stuff up with a headgun, that way you can keep it softer for longer and you don't get water disturbing the mold. Maybe even make two way molds easier by having the upper mold "melt" ontop and get into crevices.

[@teagancombest6049]

Nope that would just result in a stuck together single block of plastic if you heated the top while it was on the other half of the mold. Even if your top half plastic is too hot, it will reheat the bottom half and stick together.

[@Rodrigomezcua]

@@teagancombest6049 I remember making silicone molds way way back, and to avoid the second part sticking to the 1st one the suggestion was always to use vaseline. I think it should work the same with blue stuff

[@wezab]

Back in the day I used a mould system that allowed me to reproduce figures. It used a clay like heavy sand and two wood frames into which the bottom was filled, the model pressed in along with some match sticks and then the top half filled. The two halves were then separated and the original taken out. The halves were then joined together, there were dowels that ensured a match to both halves, and once joined the match sticks were pulled out leaving a vent and pouring spout. It then heated pewter in a crusible, (Thank god for gas) skimmed the dross and poured the pewter into the mould. Give it ten for cooling and lift the top half off. The positioning dowels forced you to lift vertically so the pewter sprue did not wreck the mould. Usually the cast would require some filing and voila I got a new gun or horse. The point is, for full shaped casts you need liquid going into a mould. The whole thing is on its way out with 3d printers and if you can't afford one but you have a mate who can, you can get them to print for you for the cost of a beer and the resin.

My suggestion is if you still have some of the shields on the sprues, chop them up so you have an injection cast. then use the blue stuff (like everyone is suggesting in the comments) with a Lego frame. make sure you use 2 half’s and keyframes for alignment with part of the sprue as close to the edge as possible for a resin injection. You want a long set time to keep the temp down (24 to 48hrs) If you feel adventurous you can use melted sprues as you media for injecting but you will have to find the sweet spot of the melting point and be in a well ventilated room.

[@zid_just_zid]

Great info for someone getting in but id recommend watching some more vids because there is a lot of depth that can be went into to perfect the usage of this mold making material :) I had some prior experience with two sided silicone molds before trying bluestuff/oyumaru that really helped me get good results for two sided stuff. Using legos for a box and a masher to get good even contact against the whole part, making the first side using clay with the bit embedded(like 2 side silicone mold making) and adding keying/registration so the two sides will locate properly against each other. A side effect of using the legos is that the molds get right angles and are a lot easier to clamp together, ive used green stuff to recreate bits but also pourable 2 part resin. Replicated a bunch of bitz for a friend of mine so he could complete both options in a necron sniper/whatever-the-other-option-is-kit. Last one sided bit i did was the front of a Space Marine Terminator torso that had gone missing, had another one so whipping up another was pretty quick and easy, i did however from experience know that one sometimes does not get it perfect on the first go so i actually did three molds and three green stuff pressing, picking the best result to use.

I've done it with Milliput, and mixed it a load with water to 'paint' into the mould for the fine detail. When that's set you can add in regular Milliput mix to fill out the mold. Works well for stuff like head recasts, but I'd never try getting something like those wings from it.

[@Hurricanelive]

For every 10 press molds I attempt I get perhaps 1 or 2 that are worth working with. If it has thin bits, strands, ropes, chains, anything that has multiple layers you can't get around I don't even bother unless I remove those bits, press mold the main torso or whatever and the bits, then replace the odd bits. The right amount of putty and a sold fit mold with possibly some weight on the top to result in the least amount of mold line and flash is a must. I would tell people to practice to the point you fill the mold flush to where it isn't too much but not too little and don't be discouraged if you end up wasting half to 3/4ths of your first putty mix kit.

[@nicolelavigne1700]

The UV resin might be having a harder time to cure because the blue stuff is blue and not totally clear. UV resin needs clear molds so you can shine light through all sides. The blue stuff is not totally opaque though so you might be able to flip it over and shine light through the bottom of the mold, though it might be slower. You can also get more powerful UV lamps than the little flashlights (like lamps for gel nails) and that might help as well. I've never used it, but the blue stuff looks exactly like Oyumaru (from Japan).

[@DustyTheKitty]

Been using this stuff for a couple years now, great for older miniatures with lower amounts of detail (squats!), have found Milliput combined with paperclips for added support really get a good end result as it's set in 6 hours or less and there's no shrinkage. Just gotta really push the epoxy into all the little details (sculpting tools at the ready!) and to not use too much of it when doing a two part mold otherwise things can really warp. Also use vaseline to keep new molds sticking together and Lego blocks to make frames to control how big/tall the mold should be.

He got the parts to add a few special weapons squads, extra heavy weapons teams, sniper squads, a extra command squad and 2 extra infantry squads. He did have to duplicate some lasguns too, but again they are simple parts. Certainly worth the money for him. Oh he used some epoxy from a DIY store, but i'm not sure which brand.

If not 2/4 of either epo or green stuff, 1/4 of JB Quick weld, and 1/4 of whatever you didn't use for 2/4's. And blue stuff casting is very tricky, those wings you made were so close i would try it again, in frame to fit (lego's are nice) and find a nice weight so when you put your top piece of oyumaru/blue stuff on it has a little weight on top to keep it all in place.

Wear gloves when using the UV light, preferably with long sleeves and any exposed skin covered. That's a cancer flashlight, which is why UV curing is usually done in an enclosure. Please be safe!

[@literallycanadian]

Depends heavily on the UV light. Many of these UV curing devices operate on the high end of the UVA band, at around 395-405nm, which is actually in the visible light range and not that harmful, particularly at the levels in most flashlights. The biggest danger is actually looking into the flashlight with it on, because its so low on the spectrum you can't see it well, and thus can damage your eyes because they don't see it as bright and know to blink.

[@Pottan23]

As opposed to the gigantic ball of unchecked nuclear fusion in the sky overhead. You know they're from australia right? Them walking to the car on a sunny day is probably more harmful than a small UV flashlight.

[@FourKits]

Those little hand-held UV lights use LEDs that emit in the UV-A range at very low intensities and pose almost no harm (long term exposure can still cause problems) when used occasionally like the typical hobbyist would. You get more exposure from 10 minutes in the summer sun than you would get from a day using one of those little handheld UV lights, just don't go staring directly into the LEDs. If you are curing resin on a regular and daily basis then definitely go for an enclosure.

[@Born_Stellar]

ahaha! for the light??? no. wear gloves because resin is some really bad stuff. you can develop an allergy to it over time if you get enough exposure. Will probably give you cancer about 1000x faster than uv light as well!

I found out that keeping the boiled water in a thermal flask (while you aren't using it / to top up your water container with blue stuff) is really great idea, other wise you might need to run your kettle often, as as soon as the water temp drop, it becomes a bit more difficult to shape the stuff.

[@Syrkyth]

Hmm, maybe a hotplate on low with pan of constantly boiling water with a floating small tinfoil pie pan? It might keep the Bluestuff very soft (hmm, maybe even liquefied - bad if it never reset) while you make your mold. You could always go the old school route and just run with liquid latex reinforced with cheesecloth or fiberglass. Not reusable but for the price difference vs material purchased . . .

Worked great for duplicating the special legion insignias on rhino and land raider doors that forge world sells so i didn't need to buy a bunch for all my vehicles.

[@scryptogram5686]

highly recommend polymorph, its like blue stuff but you get basically a bucket of it

[@RossFlack]

I use a small heat gun to heat up the blue stuff. Then cover what I'm moulding. I then let it cool sometimes I will pop in the fridge especially if I'm making a two-part mould. It will not stick to cold blue stuff. Sometimes I will use thermoplastic pellets to create a stiff shell. I avoid casting materials that generate heat as it will soften the blue stuff and make it warp or worse stick to the material you cast.

[@Finn-pe7uj]

Do you use the pellets on the outside of the blue stuff mould, or to cast with?

[@RossFlack]

@@Finn-pe7uj on the outside to prevent the bluestuff from warping the layer that the plastic pellets form is like a removable shell.

[@Finn-pe7uj]

@@RossFlack Thanks Ross. Do you prefer this method to using, say, a bottlecap or a lego mould case?

[@RossFlack]

@@Finn-pe7uj on bigger molds this helps use less blue stuff. But if the bottle cap is easier for you do that.

[@Finn-pe7uj]

@@RossFlack thanks! What is the biggest thing you'd attempt to cast in blue stuff?

if the water is too much of a problem you can try using a heat gun - difficult to handle but very clean and very fast once you get the hang of it.

[@outofthisworldmodelsandmin898]

I tried this myself using epo-putty, as seen on the plasmo video. That putty is so worth it. This is an easy method for making small replacement pieces for models/figures. Thanks for the video! This method isn't as popular as it should be. -John

[@tonygreenfield7820]

I have tried using a pourable 2 part resin and it worked well for simple push molded (one sided) parts. However when i tried to make a two sided mold (ie push the part into the first blob of blue stuff, let that cool and set and then push another blob of blue stuff to make the other side of the mold) i had to cut a pouring channel into the the cooled down blue stuff. When pouring the resin in, it seemed to go ok but on every test, the resin didn't reach the far end of the mold Plus the resin had a tendency to spill out the sides. A friend suggested that an air bubble was forming in the mold stopping the resin from filling the mold properly so i cut in a series of extra channels to help the resin spread throughout the mold but so far this is still not working to produce a decently molded part. This is odd because i have some experience in making RTV rubber molds and casting in both white metal and in resin. Oh well i will havr to keep experimenting and at least the blue stuff is reusable.

[@leesaunders5357]

thankyou for showing how hard it is to use ,you got a sub from me,looking forward to watching your future vids and catch up on old.

[@markus_glevera]

More hard - is making thin details. I bought 2 box of immortals/dethmarks, and used green and blue staff, I made 10 immortals and 10 dethmarks. The problem was with legs. I used wire inside green staff legs. It was interested experience))

[@szabosandor8806]

My expeirence: Use a lego frame. You can put the 2 part mold better with a frame and for 1 part mold you can press in harder without deforming the mold. For the water use a paper towel. Take out quickly wrap it in one for a second and then make the mold you have enough time. For 2 part mold cut air wents where the excess milliput can go so no extra 1-2 millimeter layer will be between the 2 half. Fill the milliput into the halves from one corner and spread it all over the mold so there will be no air bubbles. Then push together both halves (with air went to escape the excess)

[@clymdodds1020]

I have some reservations regarding your test methods and the benchmarks your setting in relation to high heat high pressure injection moulded originals. BUT we love short cuts. Blue is used in the industry for quick rep. There are issues with arrow head flashing. It’s not a universal fix it. But it has applications...

[@Nigelius]

While plasmos video is really good I’ve had limited success making full bits. I’ve found initially I got quite a lot of squeeze out and even with putting less in I got a lot of slightly misaligned bits. Definitely something to practice on, so don’t expect amazing results first try. For press molds blue stuff is great, I’ve managed some nice pieces using greenstuff, milliput and even gently coaxing unbaked sculpey out of the molds.

[@teagancombest6049]

If they're misaligned you need more registration marks. 3 is the minimum but more is better. Also completely cool your first half before adding the top of the mold. I like to put mine in the fridge first so it's really cold and doesn't get heated up by the top half and stick together.

[@Nigelius]

@@teagancombest6049 Thanks for the tips. I feel like I’ve been doing that and still get sub optimal results. A fully formed bit but slightly misaligned and chunky mold lines. I have a fairly adequate thunder hammer mold so I may mess with different putties and being as conservative as possible with the putty.

[@teagancombest6049]

@@Nigelius yeah I mean that's kinda just how press molds work. They're not ideal for everything. I play nurgle so pieces being chunky and sloppy doesn't bother me, in fact it could even be a bonus. I made 2 horns for my converted nurgle Ghorgon from the Rotigus horns and even the owner of my LGS said he couldnt tell they were milliput. So it works for organic shapes and textures. I haven't actually tried doing like armor or something that needs precision.

[@Nigelius]

@@teagancombest6049 Good to hear it’s working out for you. I have been using it more for organic pieces like Wolf heads and paws for my space wolves. Smaller bits that I can sculpt larger areas of fur around. So far I have a cast of Bjorns Wolf pelt which allows me to add heads and paw pelts to other green stuffing and a thunderwolf head cast which may form a substantial piece of pelt.

[@commandermcnash5137]

Hi there, so far as it goes I have managed to duplicate 2 units of tyranid warriors and one squad of Chaos Space Marines and I am currently working in a (nurglite) Venomcrawler, in the Tyranids case it helps they are biological entities, so all the imperfections could be disguised through a bit of additional sculpting and texture, for Chaos, it's actually quite good if you want Nurglite units as it actually makes the units less sharpie which is something Papa Nurgle approves, otherwise just work with some metallics and a bit of extra details so the cloned minis look like battledamaged possesed metal, which actually looks great if you want daemonic Word Bearers or gritty battleworn Iron Warriors (which is what I did). By the way, it is better if you just put little bits of milliput instead of a lot, for starters you will save lots of material and also the work of flashing out all the stuff. If you have a cook keep some water boiling near so you can save some time and always have hot water, immerse the blue stuff in a pyrex glass, help yourself with a stick. You can also use some sculpting tools to help you push the blue stuff close to the borders of the model bit when making the mold, try always to use two side molds as this actually helps you calculate better the amount of milliput you are using, besides it will make both sides of the bit you are cloning fit better. After you have made the first part of the mold immerse it in cold water to help harden the blue stuff faster, let a bit of moisture in the side which is going to make contact with the blue stuff which is going to be the second part of the mold, once applied and pressed immerse the whole mold in cold water so both sections dont get fussed. You can always fill any recess with more milliput instead of adding an excess of the stuff Don't bother with pointy bits, you better sculpt them with green stuff as its more resistant and flexible instead of the pasty consistency of the milliput. I think I will try some necrons and space marines, if anything I can make the necrons rusty like they are coming back after aeons of entombement and I can use the same trick I did with the Iron Warriors with the space marines so they look like they have been through a long campaig, maybe desert warfare this time?

[@markc1793]

If, like me, you don't have a model shop anywhere near you and you're put off by the cost of the "blue stuff", just get the generic stuff from Amazon or similar, just search for Oyumaru it's the exact same stuff, you heat it up in water, push things in it to make a mold etc.. but it's a lot cheaper and normally it's cheaper for more of it, the only "downside" if you can call it one is that it normally comes in a load of random colours.

A trick for thin plaster molds is to add a piece of paper kitchen towel to the back of the mold. This gives them some much needed strength.

[@mattthrower7391]

I've used blue stuff for a while.. replicated many figures and parts.. what i've found is, mixing GREEN STUFF and Milliput 1:1 gives the best epoxy material. Dries quicker and stronger, can be quite tough to mix the two.

[@Velcraft]

Yup, stuff gets removeable and rigid enough in just under two hours, but only gets fully cured in 24-48hrs. Premix the blue-wrapped Milliput part with blue part from GS, then premix the yellow with the clear-packed part. This way it's easier to mix together.

[@mattthrower7391]

@@Velcraft Never thought of that! I premix both which probably takes the same time thinking about it haha. But i'll give that a go.

[@valegorn]

frames will help, especially if you have a way to squeeze the putty into the mold. Also, I've found Blue stuff is great for more organic stuff (like Orcs or Bugs), not so much for things with crisp clean angles. If some have figured out a way to make it work, sweet, but from what I've found is blue stuff was my gateway drug into silicon molds.

[@SilentSooYun]

Blue Stuff makes much better molds if you first build a frame box around it. It helps keep the Blue Stuff from over-compressing when you're pressing the two halves together, and also helps keep the molds aligned. Doesn't have to be complicated, either: I use some old Legos. Very versatile!

[@Amdor]

If you use UV resin with Blue Stuff try to use flashlight for a moment, then turn it off, wait a bit and repeat. otherwise it can melt blue stuff, and it could mix with resin.

[@FourKits]

If the water is a problem then try softening it with a double boiler like you do with chocolate.

[@teagancombest6049]

Yeah the idea of using hot water in a bowl is a bad one, you need to keep it hot so a double boiler or just sticking it in a pan of water boiling on the stove is ideal

[@Primal2229]

Ive been using the no name version of Blue Stuff for a few years now and mold quality comes down to the more familiar you are with it over time. My first molds were shit. Warped, air bubbles, lots of missed details. Now Can feel when its hot enough for a clean mold or a sloppy one, know how to press it onto avoid air bubbles, how to do two piece and single piece molds to the point even painted details now show up. Kinda cool when making a mold of the JoyToy salamander shoulder and getting the emblem in the mold and in the resin to basically trace with paint. Silicone is better in a lot of ways there is no question there but blue stuff is ideal for one off molds and cheaper in the long run. Silicone molds have tear out and generally just degrade overtime where the only use becomes getting chopped up for chunkies to be used as filler in a new mold. Blue stuff you remake it.

[@warbanda]

I mix greenstuff and miliput it works well 👍

[@Interzone88]

Make a lego box. To make the part I pack the bluestuff mold gradually with green stuff. I fill the mold by adding small amounts of green stuff and pressing it hard into the walls of the mold with a dental tool. You get a better impression and less flash. For two part molds I pack each half seperately and then press them together.

if you put it in boiling water on the stove so the water stays boiling and pull it out you will get a longer working time and it will get crisper detail

[@Molikai]

The main probelm I found with blue stuff - when you peel them apart to remove the original? It distorts the mould. And as you've discovered - it has no 'overflow' method for excess moulding material.

[@hightde13]

On an odd side note, if you can, it would be interesting to see you try that plaster stuff from Jakie's Not another Crap Kit. It seemed to set a little harder. Nice video! Thank you!

[@Allan_Lugia]

As one who already have tried this using: Grenstuf, Greystuf, Both takes good details, issue with correct among in the mold, so my miniature always gets to thick. +2-3 mm to much. miliput Black/white/yellow? all 3 takes good details, black and white more than yellow for reasons?. but i find them way to brittle, AND sticky. it get everywhere.. i kinda hate it. Greenstufworlds acrylic resin Stone-cast? ( it works the same way as acrylic resin). I am not sure if i didn´t let it dry long enough, but the small spikes on the wings you used just cant survive, also working with so think layers... it kinda breaks all the time. UV-resin. Melts the bluestuff, if its more than 4-5 mm thick when poured.. sadly, it does works wonderful. All this above is combined and tested with Blue stuff. You can use gresstuffworlds 2part silicone, and UV-resin for one sided forms/molds. It works amazing, and the details are fantastik. However i am waiting on being able to afford 2-parts epoxy, for making a dobbelt sided form, with silicone. ( maybe in 2-3 months, i am able to test it). But i will make the typical Lego box and make a 2 part form/mold with a hole in it. And then pour 2parts-resins into it. This should work. Also have you tried using Miniature Hobbyist idea of sprue gue? ( recycled Gw plast, with acetone), it seems very durable but due to the process it seem to lose details. I am trying to figure out if it could be avoided... Now.. I have seen that the 2-part silicon can stand indirect heat. so i where thinking of heating Gw-Gue/plastik and maybe even the mold to the plastick melting point, and either pour it into the form... or find a pressure delivering system(not that i think ill succeed with my current knowledge). But this should be much more effective and a better more durable quality. This is as far as I´ve come with the same though process as you have.

[@sandtable8091]

I've had some success, and failures of course, in making stuff for WW2 vehicles. Spares such as tank bogie wheels, odd lengths of spare track links and jerricans are pretty straight forward. Larger items like turrets are just too thick and heavy. I've tried some tank commander figures at head and shoulder level which have been fine but whole figures are prone to huge failure rates. Not impossible but very hit and miss. It requires you to pick a very simple pose.
