Little tip for fixing the shape of the mold. Don't use just rubber bands! They'll apply an uneven pressure on the mold use pieces of wood or any hard material on two sides of the mold and then apply the rubber bands, then you'll get an evern pressure on the mold which will result in no imperfections of deformed parts.

Just came across your channel. Thanks for helping beginners become familiar with more complex topics. As an Imagineer, one of the things we saw a lot were people wanting to work on features that simply didn't have enough experience. Folks, these basics can help you become far more familiar with the dynamics involved in the entire process... And you will be able to show demonstrable ability to get and retain very fun and creative positions at great companies.
David D is awsome!...for the folks that dislike, well there is no cure for their ailments...whatever they may be....model building requires creativity, enginuity and a lot of common sense....as well as reading the instructions for resin handling....this hobby is not for you if you don't have any sense for using gloves if you have sensitive skin....OTHERWISE....David D aks PLASMO is one of the Best and shares his thoughts, skills and knowledge. and lastly his artistry....WOOT
Thank you Plasmo! This is one of the best tutorials on mold casting I have watched. You have me wanting to invest in a vacuum pump and start casting parts I have customized into parts that are not readily available. You always amaze and teach me something each time I watch your videos.
I can't believe I found you right before I started collecting "Angry Space Soldiers", I saw you making molds for "Bugs" from 2016 talking about blue stuff by random luck. This is awesome.
When you make 2 part silicone molds, try using acorn nuts to press locating pins in your clay. They are smooth and perfectly tapered so that they pull out cleanly and even if you use the water based separators they seem to very rarely, if ever, break. If you are still worried about breaking them, use the water based separators on everything else, and use some petroleum jelly on a cheap model paint brush to paint the jelly on just the locating pins before you pour your second layer. I have had some items that required a 3 or 4 part mold to be able to get all the details and using the acorn nuts for locating pins has been the best way I've ever found to work. Also, size the nuts you use to the size of the mold you are making. The larger the mold, the larger the acorn nut. Remember, you only need 1 acorn nut threaded on a 20-25mm long screw to press in all the locating pins in your clay. That way you can afford to have them ready in several sizes depending on your mold. You never want to have too small locating pins. One last thing. If you have vacuumed your silicone, try pouring it in a very thin stream, starting in a corner of your mold, and allow it to rise up around the part, that way, if you use the fine stream, you don't get bubbles trapped, and you don't need to vacuum the mold after you have poured it. The stream size for the parts you showed casting should never be larger than 1.5-2mm in diameter.

You are truly the master! Been following your channel for a long time, but every time you manage to surprise me. Your videos were one of the major motivators to start building models, and I've learned much from them.
Thank you for sharing this with us, I found it very easy to follow and very informative. I have some models I made that I want to cast and your video has given me everything I needed to know!
I regularly make silicone mould’s for fishing lures and use Lego to build my mould frames. The secret for making Lego frames is to carefully cover all the joins in plasticine. The silicone won’t leak out that way. Also, I use petroleum jelly as a mould release on the silicone when pouring the second half. Just brush it in VERY lightly.
You can make a very good vacuum chamber using a common pressure cooker such as is used in canning fruit and vegetables. Just put the proper brass fittings on the lid and you are good to go. Very safe and easy to do.
You sound like you're talking about pressure pot, used when casting the resin to eliminate bubbles in resin. Vacuum chambers aren't made with pressure cookers generally
@@matt9736 No, but; they can be. I've done it. If it will hold pressure, it will hold a vacuum. The same principle applies. Pressure cookers are readily available and cheap. A small amount of effort turns it into a vacuum chamber.
Be mindful that SLA/DLP resins often have chemicals that inhibit the curing of silicone, especially Platinum cure, that could leave your original and mold unusable without significant cleanup and loss.
What Nuke Dukem said. Tin-cure silicone usually works better for copying printed resin parts. Here's a video where someone experiments with casting copies of SLA resin models. Tin-cured work the best. ua-cam.com/video/RC9TgAO5mGo/v-deo.html

Seal the Legos with clay or petroleum jelly If you don't have access to a pressure or vacuum pot, you can reduce some of the bubbles with a thin pour at height. A vibrating table (or other agitating method) can also help. For casting, some people have used pressure chambers to crush the bubbles. I've never tried it with clear parts, so I don't know how effective it might be for that. For multi part mold making, I've used silicone lubricant spray
Really nice video! Two things I found when casting are - i/ 'Vaseline' - aka Petroleum Jelly, is an excellent release agent for making two part silicon moulds. ii/ Dusting the inside of your moulds with Talcum Powder - aka Baby Powder [and removing any extra with a soft brush], before pouring casting resin is an excellent way of making sure even tiny details and mould cavities get filled perfectly, for best quality reproduction.
Silicone mold release with Teflon is about $12 a can, you can buy it from your local industrial supply or even Amazon. You get a much finer consistent layer without having to fight with the sticky petroleum jelly.
@@Lord_Dakota it is bad for the small individual sculptors working for hours it is slightly immoral to recast for yourself but if you recast for commercial sale that is considered a fellony and is actually a pretty big crime it also breaks the copyright law so it is illegal
@@DD-bv9jl The small individual sculptor already got paid his salary by the big companies. You are only taking money away from a multimillion dollar corporation
Hi. Do you think vacuuming the urethane works better that using a pressure tank to get bubbles out? Most videos say vacuum the silicone mold and use a pressure tank on the casting resin. Thanks
Hi Plasmo, nice video and good explanation. I noticed you used a vacuum chamber to get rid of the bubbles in making the mold. However, there are some videos that recommend using a pressure pot to pressurize the resin in the mold for bubble free casting. However, I do not see you using a pressure pot for your casting. Bubbles will be created in the resin when the 2 parts of the resin are being mixed and stirring it will cause bubbles to form in the resin material; hence the need to use a pressure pot to get rid of the bubbles. Please advise should we use a pressure pot or vacuum chamber. Thanks
Mám na tebe otázku, co mám dělat když jsem chtěl vyšroubovat trysku na airbrusi ale zlomila se a část závitu zůstal v pistoli? Stalo se ti to už někdy?
Congratulations! Much better than the result I've got on my video, were I failed on casting the small pieces and ended up cheating and printing stuff on my Elegoo Mars printer (^_^) and I do use lego blocks, it is more fun and I can use some hardware store silicone to seal the gaps.
This isn't entirely true, economies of scale need to be applied. It's not wrong per se, but the cost is reduced when amortized across the total production/demand.
I am intrigued by the idea of casting jet aircraft afterburner exhaust nozzles, would you mind showing that process in more detail? I have not seen any one cover this before.
Consider punching a hole from the bottom of the side that's most difficult (like the wheels), and when they're cured, push some air in there with pressure. The piece should pop right out, because the silicone is expandable.
Hi and thanks for the tutorial. I have a question , is there any separator liquid I could use for a painted figure i want to recast without damaging the original figure (it is painted so i cannot put acetone on it) ?
Great tutorial mate thanks! It's the wheels I'm needing to do for a build! This new airfix Cromwell the wheels are wrong so needing to cast my Tamiya ones for it in resin!
I have figure resin from adalbertus 54 mm Wojna Polsko-Bolszewicka (Polish-Bolshevik War 1919-1921) but the problem was the figure only one body and 2 head, it was too bad if one of the heads was assembled to figure body and I think the way casting or molding was great idea 💡👍 from Indonesia 🇮🇩
Little tip for fixing the shape of the mold. Don't use just rubber bands! They'll apply an uneven pressure on the mold use pieces of wood or any hard material on two sides of the mold and then apply the rubber bands, then you'll get an evern pressure on the mold which will result in no imperfections of deformed parts.
Good tip Adam
I use paper tape
Yup, even two piece of thick card - just to stop the elastic bands digging in or distorting the corners/edges.
I use duck tape.
Use any hard part. Thin wood, plexiglass, something that will not bend by rubber band.

The results are amazing
Beautiful video thanks so much 👍
A vibrating cellphone to make bubbles rise to surface before inserting object to make mold of?
what is the difference of using 1 stage / 2 stage pump? is it still possible to create a bubble free silicon mold with 1 stage pump? thanks.
how long do you have to vacuum for, after you pour the resin into the molds? for the whole time it takes the resin to dry up (1 hour or more)?
Perfect, which kind of color do you use?
I wonder if an ultrasonic cleaning tank might vibrate air bubbles out? Or might it accelerate the curing of the silicone?
great work 😀👍🏻

Would baby powder work as a separator for the bilateral mould?

This and the fact that usually they're not made in large amounts. They're easy to make, but require quite a lot of work.
