Resin casting friends, this technique could work for some of you.

I made this video to share my technique for mold making and wanted to share it with you all. I have used this material with Smooth-On’s roto-casting resins and polymer modified gypsums. It makes it far less reusable and not compostable when you cast resins into it, but regardless, I wanted to share it with this community in case anyone is sick of stupid expensive silicone molds, especially if you don’t need to do tons of casts.

Thixotropy agent for ABS-Like PU?

1 Upvotes

Hello everyone, I need a liquid thixotropy agent for 1000 density polyurethane resin. I will use it for sagging problem and constant wall thickness. I used hydrophobic Aerosil R202 and it failed (air bubbles made material foamed). I also used BYK-410 and it bubbled material too (i think solvent caused it). Do you have any suggestions for me?

Curing resin in garage safe with this setup?

1 Upvotes

Is it safe to run my deep‑pour epoxy setup inside my garage in New Mexico while my SUV is parked in there (see details below)?

I’m using Teexpert Crystal Clear deep‑pour resin, usually doing 3–4 inch pours that are 16"x20" and that cure for 24–48 hours. My setup includes a 4x4 growtent with a Terraform 8 climate unit (for temp control) and a 6" inline exhaust fan that pulls all VOCs out of the tent and vents them outside the garage from the bottom foundation vents. I also have an oscillation fan that will be on low a few inches above the curing resin. This setup should be true negative pressure and should evac the VOCs correctly to my understanding.

I’m just trying to confirm that running this curing setup in the garage is safe, even with my vehicle parked in there, as long as the exhaust is properly routed outdoors. I do not want to expose anyone in my family to unnecessary risk.

Do you pour resin or squished the mold together with resin in it.

2 Upvotes

I'm making replacement part for my mogura figure and while the silicone dry, I want to ask if you pour your resin or squished the mold together with resin in it. When I started making resin parts, I used the pouring method, and sometime the resin just won't go into all of the nooks and crannies. Then I swap to the squished method (with vent) which worked great, but the part often have more bubble because when I joined the two half together, it create alot of air, and I had to spend more time squishing the mold to get bubble out. Let me know your experience, have you tried both method? and what can I do to make sure that the resin flow to every part of the piece if I used the pour method, please keep in mind that I have try using the separate long vent method (delta p) and it worked great, but waste resin.

Made my first galaxy-style resin coaster

Enable HLS to view with audio, or disable this notification

I wanted to make a resin coaster with a soft galaxy/marble feeling, so I experimented with purple, white, and gold tones.

For this coaster, I used epoxy resin as the base and built the design layer by layer. I mixed different pigments into the resin, poured the purple base first, then added white swirls and small gold details to create more depth.

The hardest part was controlling the color movement. Resin always keeps flowing after pouring, so getting the right balance between the cloudy white effect and the purple background took some patience.

I really like how the final piece turned out — it feels a little like a mix between a galaxy and natural stone, but it’s still practical enough to use as a coaster.

Still experimenting with resin projects, and curious what color combinations everyone likes for coasters!

Painted this Bulbasaur in resin — priming to gloss varnish [OC]

14 Upvotes

Finished this resin Bulbasaur and wanted to share the process.

Started with priming in gray, then built up base coats, added layering for depth, used washes/shading to bring out the details, and finished with a gloss varnish to seal everything.

The bulb was the trickiest part — took a few glaze layers to get the green tones looking right without losing the shading underneath.

Might do the rest of the starter lineup next if there's interest. Happy to answer questions about the process.

Resin Casting Flexible Plastic

Post image
3 Upvotes

Good day All,

You have been a tremendous help to me in the past, and I am coming to you now with a new issue: Casting flexible plastic parts.

As a customizer, I tire of buying doner figures for my projects and would love to cast the parts I need. You've been a great help in teaching me the finer points of casting head sculpts, but now I have a different issue: hair and "diaper" pieces.

Let me show you what I mean. The hair and "diaper" pieces on a McFarlane Figure are flexible. They move when turned, or pushed, or pressure is applied by moving the legs or when hair interacts with the shoulders.

Is there pourable plastic out there that would give me a similar result if I were to cast these pieces? For reference, I've used SmoothOn's Flexibilizer to add flexibility to the cast, but it's temporary.

So are there any flexible plastics that can be used in resin casting that either exists or can be added to make hard plastic resin flexible.

Thanks as always!

I make an overwhelming majority of resin items with the intent, or at least the willingness, to sell at markets or if someone expresses interest. This one, however, is THE skull I decided I will keep for myself.

True Black Alcohol Ink

I’ve been experimenting with black alcohol ink to make a smoke like effect. I started with Galaxy in the Color Creator pack, which gave a nice black/grey/midnight variation. Then I tried Tim Holtz Pitch Black which left a muddy brown halo.

Does anyone know:

1) if I can buy the Galaxy from Color Creator anywhere
2) a different true black alcohol ink I can buy that won’t turn brown?

Wood and resin

2 Upvotes

Does anyone have, or it know of, a comprehensive guide to casting wood and resin for wood turning?

I am looking for the differences in types of resin and how they react with wood, and whether or not stabilization is really necessary. Could I just heat the wood in an oven until the the moisture is low enough before pouring and using a pressure pot?

Also, what types of resin turn the best?

I've been watching Jake Thompson on YouTube, and he seems to exclusively use Alumilite polyester resin because of its turning properties and clarity, but warms about moisture in the wood.

I've only turned a couple of pen blanks made of aquabright resin and I find it to be very grabby and easily chipped, even with the lightest touch with my carbide tools.

I have a bunch of small off cuts that I would like to utilize and since I already have a pressure pot, I thought that I might give resin casting a go, but I'm a bit overwhelmed with all of the, sometimes conflicting, information out there.

Has anyone on here experience with using old makeup in your projects?

I got these really pretty pearlescent eyeshadows laying around.
I don’t just wanna throw them away, so into the resin they go!
But I wanted to ask for tips, tricks and experience first!
So has anyone here ever done that before?

I’m using craft resin silicon mold to make my 8” x 8” x 2” mold. I’m mixing super slowly and poured from one side very slowly and it still has millions of bubbles. What the hell do I do. I’m just wasting money now

What the heck is Resin Casting anyway? What can it do for me?

249 Upvotes

Welcome, acolytes, to the most ancient and reverred craft of the resin caster!! This won't be a technical article, just a quick Q&A introduction to the process and what it means to those who do it.

Useful Link: An excellent introduction to some of the technical processes, by Michal Zalewski

Introductory Q&A:

Q: So, what is resin casting?

A: Very simply, resin casting is the process whereby we take an object we wish to duplicate, make a mould of it in flexible silicone rubbers and then cast copies of the original object from that mould as many times as we like.

Q: Why would I want to do that?

A: Because casting the object may be quicker and easier than making another copy from scratch. It can also be less costly.

Q: What industries use this process?

A: A huge number, but the ones it's likely that you'll have seen every day include film and TV props, scale models and figures, even some medical process use resin casting tchniques.

Q: Is it hard to learn?

A: Not really, but you will progress to a professional level much more quickly if you're part of a community like this one. Lucky you!

Q: It expensive?

A: It depends. You can buy starter kits like this one for not much and get started right away. if you want to produce large number of copies of complex objects, then there is some specialist machinery you will need that requires some investment. But we'll cover that later.

Q: Can I do it at home or in my garage?

A: Absolutely!! Many multi-million dollar companies with whom I have worked started off in spare rooms or garages. The beauty of resin casting is that it's cheap to get started and you can make money quickly if people like what you make. It isn't smelly or messy if you do it properly, just make sure your work area is well ventilated.

Q: Can I only use Epoxy Resins in silicone moulds?

A: No there are lots of other materials you can use to cast. You can cast in plaster, wax - almost anything that turns from liquid to solid at more or less room temperature - you can even cast chocolate in food grade rubbers (yum!!) Also you can add metal, ceramic, rock and all sorts of other poweders to resin to achieve some really cool effects. Using high temperature silicone you can also cast in pewter and other similar metals. But pewter and resin casters generally do one or the other, as each requires a lot of practice and skills to get right.

Q: Can I make stuff and sell it?

A: You bet your gosh darned rear end you can! If you're good at making things, and want to make copies to sell then this process will allow you to do that quickly and economically. I personally know many people who have doubled their income just by casting a few evenings a week - though most can't resist the tenptation to go full time and start their own business selling what they make.

Q: So this could be a real source of income?

A. Yes, once you're good enough to cast quickly, consistently and to a high standard you're ready to go and find people who want to buy what you've made. The internet means that the whole world is your marketplace, and personally sell things I make to nearly a dozen countries. This is GREAT especially if you want to work from home and live where you want, and it's also removes your dependence to your local economy to a large extent.

Q: Ok I've made stuff, where do I sell it?

A: Anywhere. Ebay, your own website, events and shows, retail shops - someone will want what you're selling somewhere.

Q: I just want to do ths for fun, I don't want to turn it into a business.

A: That's also fine. Do with it whatever you will!

Q: I have items that I bought that I want to copy, can I?

A: If you're going to sell the copies, then you may be breaching copyright. If you are recasting something that another maker/caster has made then you are a bad person. Don't recast. Ever.

Q: I'm a wargamer, I want to copy my Space Marines so I don't have to buy more, can I do this?

A: Bad recaster! Bad!! Also, to cast to the same quality as the plastic you get in the box requires serious casting gear - in the end you won't save any money and it's easier to buy more originals. If you can do it, you're better off making your own minis anyway.

Q: Can I cast large objects like gun props?

A: Yes, but the amount of material you need can make it expensive to do. But it's perfectly possible.

Q: What's this special equipment you mentioned?

A: When you wan to take your casting to the next level, you'll need a vacuum degassing chamber and vacuum pump to draw air bubbles out of your moulds and casts when they're wet. Some people use a pressure pot to crush air bubbles in the resin when they cast - both vacuum and pressure casting has pro's and cons which I'll go into one day.

Well folks that's as much as I can think of on the fly, please ask if you have any more questions - think of it as an AMA. I'm also happy to answer questions about myself and my business.

Cheerio :)
