Another great resource Bill, this and the silicone video are a great starting point for aspiring propmakers!
+Smooth-On If you would only sell in Belgium :'(
+Pieter-Jan Geysen I know a german shop which delivers also to Belgium: Its kaupo . de They sell almost all Smooth-On products and maybe this is a possiblity for you.
Dear Bill, I need a resin that will resist deformation in direct sunlight. I’m making a sort of emblem/badge for a car but I need it to be clear and I don’t have any experience with resins or casting for that matter. I was wondering if Smooth Cast 325 would be suitable for my application or is there something else you recommend?

Started with EVA foam, then 3d printing now I'm here resin casting. I love you guys super helpful with every new step I take!!
That's wonderful!!
Great video as always Bill! It may be beneficial to your viewers to touch on safety precautions while using urethanes, especially in enclosed spaces. Also, I know of several people who found out the hard way that they were allergic to resin because they weren't wearing gloves while casting. Always good to encourage proper handling of chemicals, have fun without hurting yourself!
Who would down vote this video? What could possibly be offensive to someone in this video? Thought it was great - informative, interesting and well made. Thanks.
Got your Ebook yesterday, I must say its very informative and well written.
I loved the cut to your brother, "Uh... science!" That was great.
my girlfriend bought me your book for my birthday and it just arrived! I'm so very happy right now!!!
Thanks so much for these Bill!
I recently bought myself some silicone and urethane to start making molds but I've been a little nervous to actually start using it but after your next episode I think I'll be ready!
keep up the great work!
Awesome video for a noob like me! At 7:00, you said a good mold should last about a dozen times. What if I need a mold to last hundreds of times? What materials for the mold can be used instead?
Context, I'm pouring a clear, flexible 2-part PU onto custom shaped flexible LED strips and need to create walls around the edges of the LED strips to keep the PU from running down the sides.
If you're lucky you can get a lot of pulls like that, but it all just depends. If you're pouring something flexible then you'e more likely to need a rigid mold, in which case concrete or something similar might be more what you're looking for, and also typically lasts longer.
@@punishedprops I'm thinking more for mass manufacturing, not so much hobby work. Have you tried molding PU with teflon or UHMW?
You're really killing it with all these great videos. Keep up all the awesome work!
great vids,im brand new to this stuff and so far you've answered all my questions. Thanks!
I just got your book, and it's helping so much for my first foam build!
And your "Molding & Casting 101" couldn't have come at a more perfect time because there's a gun I'd like to build that would go with my armor. The instructions and descriptions are super clear, so thank you!
Alsoooo... I'm not sure if someone's mentioned this, but the videos you list at the end aren't clickable like they usually are... If you could let me know what that first video is, that'd be great! :3c
Can't wait until next week!
Keep up the great work bill! your videos have got me into prop making. :D
Thanks for the video! I've tried Smooth On Onxy Slow but on multiple pours, its coming out almost with a stiff rubber like cure. I wanted stiffness similar to what an ABS plastic would be. Got same results with another manufacturer. Any suggestions on what I may be doing wrong to mess up the cure? Would they need to be heated during cure? Should it be mixed and poured at a certain room and product temperature? Any advice much appreciated.
Great tutorial 👍 but one thing remains unclear even after a few replays, so I'm hoping someone can advise..?
So, after filling the mold you talk about putting it in the pressure pot and apply 60psi ambient pressure to the outside so that any remaining bubbles in the resin would compress to micro size.
However, later on (5:10) you come back to the pot to retrieve the mold and you comment that it's now time to release the vacuum from the pot.
So what was it during those cure hours? pressure or vacuum?
You talked about tinting to change the color, have you ever tried painting the inside of the mold and then pouring the resin in over the wet paint to color the casting? I have heard people talk about doing that before and I'm curious how well it works.
Got a question, ive found a lot of videos and tutorials on the resins and the molding plastics themselves, but im actually wondering what type of materials you make the master out of, the original item that you make your rubber/silicone mold out of. The original model
that joke at the beginning killed me, like after I laughed I couldn't stop coughing for five minutes straight, but so worth it XD
Nice video. I have made 2 piece molds. But wondered if i should of used different materials for what i am making. 1/64 scale detailed car. The mold worked.
I used allumilite resin. Didnt work for me. I was listening to your video. Was curious about adding color. White= not good for color? Clear=good for adding color?
Hello, Does it have any toxic fumes? What do we do to use it safely? Do we need a respirator when working with it?
Great video!
I wanted to ask if you use any kind of filler to make the finished part less heavy or is that the way they´re supposed to be?
Something no one seems to cover is the clean up process. What is the process for cleaning your measuring cups and mixing tools after the pour? Or is it all disposable and not salvagable?
I want to make a clear full helmet and was wondering what your recommendation on which resin i should use.
Thanks Bill! I want to start mold making project with my 9 year old son and your videos are always super instructionals. Thanks for putting in the time and effort. What other brand of resins would you recommend instead of smooth On? It's harder to come by in my area of Canada...
***** Thanks! I found a specialized shop nearby thanks to you...Can wait for the next video!!!
Can't wait for the rest!! Will you be getting into things like helmets/masks?
In terms of strength which one would you recommend for casting joints for figures?
May I ask what Smooth-on product is an hard casting but still flexible I'm looking something like a polyurethane rubber 80-90 but I see that smooth on only stop at 60 please for some advice.
amazing. you're amazing. always amazing
i vacuum my resin before pouring. I get bubbles inside my molds even though i manage to vacuum all the bubbles inside my pouring container. Any suggestions? Maybe drying out my molds?
So If I’m trying to make spiderman raised webs on a suit. What type of urethane should I use? Need to be slightly stretchy. Any extra info is appreciated
does urethane casting resin SMOOTH ON 66 D stick to pvc board
What is you want to use Urethane to make a Polystone statue? Got a friend that owns a granite shop that saves me his dust...which Urethane would you use?
wait. so. which resins are more hard. and which are more soft? i need to het my hands on a harder one.
That’s what she said.
Dude... we are ALL twelve. :-)
No....I'm 14
I see you you just let it stand instead of using a pressure pot. Do you have any problems with air bubbles? Do you use a respirator or is it not needed?
I do use a respirator! At the time I didn't have a pressure pot, so bubbles would sometimes happen. Now I use a pressure pot even if I don't have to because I can! But most molds are okay without a pressure pot - it depends entirely on how the mold is set up.
many thanks for the video. I need to cast something that needs to be strong and tough, not a slush cast, solid body in a mould. what would you suggest as a great tough resin ?
Does polyurethane differ much from urethane for casting? Being in the UK and finding decent equivalents can be a real drag.
bill i have a question. if i want to make a mold from clay can i used oil based clay so i don't need to buy another clay if i want to make another mold? thanks
Hello, what kind of resin would you recommend for outside use. Moisture and sun. That last long and is pretty hard plastic? Thank you.
G'day! Silly question - does the urethane also have issues with bubbles, that require degassing?
Hi I am planning to work on Tidus Brotherhood and would like to ask if there's a way to add air bubbles inside my cast?
Just FYI. The links at the end of the video don't open the videos. PS still love the Armorsmith books I got on Black Friday.
So once a mold begins to degrade what would you suggest? Should you make a new mold from the prototype or could you use one of the resin copies?
+Bill Doran Thanks, I wasn't sure if using a resin copy would be advised.
Dear Bill, I need a resin that will resist deformation in direct sunlight. I’m making a sort of badge/emblem for a car and I need it to be clear but I don’t have any experience with resin or casting for that matter. I was wondering if Smooth Cast 325 would be suitable for my application or is there something else you recommend?
I would ask the folks at Smooth-On. They're super helpful! twitter.com/smoothon
So last week you mentioned (&/or linked to) vacuum degassing the mould. Do you pressure cast your resin?
***** awesome. Thanks!
Hey Bill!
I rewatched that video like 4 times now and still keep finding something useful every time! Very helpful like all your content) But I still have a question. Smooth On is cool and all but sadly I need to travel 500km to nearest shop that sells it, like straight in Moscow. But suddenly today I`ve been informed that someone starts to sell Polytek products in my town. Question: is Polytek a passable alternative to Smooth On or should I man up and spend some cash on tickets\delivery?
P.S. Sorry 4 mah english.
Thanks sempai, you are so nice. My pile of Dark Souls projects will be done with your knowlege!
Hi Bill I hope you'll still field questions on an old video lol I'm just starting out so please forgive if you already went over this. You talk about tinting the resin but couldn't you just paint the final product instead of relying on whatever color the tint gives it? Any help would be huge!! Thanks man.
You can absolutely paint the final product! Tinting the resin an help in a few ways: it provides a base color so if paint rubs off or is chipped you don't have bright white or some other color showing underneath. It can also save you a lot of time to tint the resin rather than painting, but you can totally paint it too.
What product would you recommend for something very long wearing like longboard wheels?
Since the heat from the curing process ruins the mold, would it help to cool the mold down during curing?
Nice video, what type of resin would your recommend for something that needs to be very rigid like a lightsaber hilt?
I wonder, what about using polyester resin combined with cold casting metal particles.
Hey, I'm from Ecuador, I really want to try molding and casting and these videos have been quite educational. Of course the problem is the products you use aren't available at all in Latin America. I'm doing my research on finding equivalents or substitutes but information is confusing. Do polyurethane resins work the same as urethane resins? Almost all silicon products in my country are the typical silicon caulks. I think I'll travel to US just for materials, lol.
I can't say with any certainty that those materials will work the same as what we use, but you may just have to experiment and try to replicate our results.
Thanks for the answer, I'll take the risk.
Hey getting ready to do my first craft a sword, I want it to come out like the cold steel polypropylene swords, what should I use specifically?
I'm not sure about resin - you should ask Smooth-On. Their customer service is the best at helping you figure out what product would be best for your project. To get the metal look you could do cold casting or try using graphite powder!
Hi Bill! I was wondering if urethane resin would cure into a squishy texture if I play with the ratio? say 3:1? 1 being the hardener? I don't want to use polyurethane because I want the 'mochi' like texture which you can't get PU
+aoichi shiyuki I'm not sure. That's a good question to ask the folks at Smooth-On. =)
aoichi shiyuki I would not recommend changing the ratio. Just look for a softer urethane. For instance, I didn't make my ratio right and it never really hardened, it can stay sticky. Just get a softer durometer
Bill, can you recommend something for rotocasting that cures clear? I am looking to do an arm for an Invisible Woman costume.
I'm not sure what exactly you'll want off the top of my head, but I always aim for 10 minutes or so cure time when rotocasting so I have time to slush but don't have to wait too long for it to set.
I'd check with the folks at Smooth-On, they'll be able to give you the best recommendation!
Terribly sorry if this has been asked already but are there any other places you can buy this stuff at?(any stores specifically?) mostly the Smooth-Cast Onyx Fast?
thanks man
I'm working with 325 and 326 right now and am having some troubles with inconsistent amounts of bubbles on the surface of the open face of my mold. Any suggestions beyond degassing sense I havent been able to swing the timing being able to fill and degass before it kicks?
A high, slow pour is the best way to avoid bubbles. Pour in ONE place and let it fill the mold slowly to avoid air being trapped
do you know about some urethene rubber or liquid urethene foam that is similar to the latex texture like the LARP weapons ?
Any resins or epoxy you would recommend that cure clear for a hard plastic finish on props?
Hi,
I have a question.
how does smooth cast 65D feel? Do you feel that it’s plastic or do you fell the quality? Because I want to make high quality statues. And it shouldn’t fell cheap when you touch it.
Thank you.
I haven't really messed with 65D much, so I'm not sure
Hey Bill, do you know of any additive for resin that will make it more pliable once cast and not so rigid? Thanks.
There are resins with a variety of durometers. Ask the folks at smooth-on.com and they will be happy to help you find what you need.
When casting an EVA foam prop, how far into the making process do i have to go? Can I cast it once its been plasti dipped, should i continue from there and prime/sand? If I have an already fully painted and sealed foam prop, is that ok to use without destroying the prop? I'm about to dip my toe into this because I have so many one-off pieces I've made out of eVA.
You definitely want to make sure your foam is well sealed, but other than that the timing depends on the surface quality you're after! If the surface right after PlastiDip is one you're happy with, go to town!
@@punishedprops Thanks!
Hi I need a resin or urethane to case some action figure accessories. Something rigid, but flexible enough to bend without breaking. Anything that you might suggest?
I would pop over to www.smooth-on.com/ and ask the folks there. They reply super fast and are GREAT at helping you figure out which product is going to work best.
Please tell me which material I need to use for abs sheet forming die ..
I had a question regarding pouring smooth on 300 into a plastic trash part of a pencil purchase. I mixed and poured. It activated quickly. I checked it 2 hrs later and it was rock hard. However, it ended up binding or melting the smooth on 300 to the plastic trash mold. With difficulty I was able to pull the plastic mold off, but am ready to call it a fail (experience) Did you encounter anything like that? Any way to avoid this?
Resin curing creates an exothermic reaction, so it gets VERY hot. Your mold is probably not the right material to use with resin and because of that it melted.
What kind of pressure chamber would recommend for large castings?
Thinking of making a 55 gallon steel drum into a pressure chamber and rate it at 60psi.
I cannot recommend building your own pressure pot. It's basically a bomb. That kind of work is best left to certified professionals. I bought my 5 gallon pot from these guys and it's amazing: www.finishsystems.com/resincastingpressurepots.html
Anything on the market I could get a sheet pan into? (18" x 26")
Id like to see a video on making a rotacaster
Love you forever Bill
I want to make a silicone mold of the life size skull. What you recommend to me, brush mold or the technique that you used, two parts mold? I thinks if I use your technique will be a lot of silicone material or resin.
I like the Smooth On
I think a brush on mold would be best.
Punished Props Academy Thanks, I have to practice with brush on with Rebound 25. I'm thinking about business, which one is better to reproduce and economics too
Hello im new to your chanel, what is the best resin to use for making quality strong rc parts with molding method?
Do you have to apply release agent when you're rotocasting by spraying it into the mold?
+Bill Doran Thanks for the tip! Would the normal spray on silicone release agent work?
Thanks, very informative!
You're welcome!
Just wondering, could I used a polyurethane resin to roto cast and prop helmet?
Hello. I’m wanting to make a mold for a prop axe head and I wanted to know would it be better as a one or two piece mold? Any help would be appreciated.
It depends on the shape of the axe, but I'm gonna guess a two part mold will be necessary.
where do you buy this internationally
can you get this on Ali express or ebay ?
Will adding more dye darken or brighten the color of the white resins.
More dye will make the color darker, but remember that the resin cures bright white, so the final color will always be diluted with white. That's why you can get "color match" resins that are mostly clear and don't dilute your dye colors. SmoothCast 325 is a good example.
@@punishedprops thank you
A year later and i still find the "Uhh.. SCIENCE!" Part hilarious lol
+Chelsea Acosta Hahaa! It's classic. In need to use that clip more.
Could you please do some tutorial on polyurethane rubber props? can polyurethane rubber liquid be slush cast as urethane resin?
It depends on the rubber and the type of prop. I'd head over to the Smooth-On website and check out their tutorials! They have TONS of great info on different materials. I haven't done much work with urethane rubbers myself.
cool.. thanks..
What resin would you recommend for a flexible tho high tear resistant and clear like glass cast.
I'd ask the folks through the Smooth-On customer service! They're super helpful for finding the right material for a project.
I made a face with WED clay and I planing to put on the wood and hanging to the wall. Somebody told me that sculpture will be fall and broke. Is that true? Is so, what can I do? Is there any product to seal the clay and be protected for cracks?
I don't have much experience with WED clay, but I've mostly seen it used to sculpt a master that is then molded in silicone so that rigid, resin copies can be made of it.
Do you guys ever have any problems with air bubbles in your resin casts? I'm having trouble finding a full proof method to avoid those tiny surface bubbles.
Bubbles are a fact of life unless you use a pressure pot.
i am wondering if you can use it as a glue to join two urethane resin pieces toghther to make a permanent bond of two pieces since some pieces need to be molding seperately?
You CAN, but you want to make sure it's the same kind of resin and make sure you do it soon after casting the pieces. You'd also need to rough up the surfaces you're gluing together, and you'd probably have a good bit of sanding and clean up.
@@punishedprops I see ill do it if them thing needs to bee seamless. if it not seamless ill just make it attachable.
What is the best casting resin if Im trying to make a mold for vacuum forming and want the mold to last and be used many many times? Im vacuum forming hockey masks and my bucks/molds that I'm pulling from do not last and are not good at all. Please help!
I'd ask the folks over at Smooth-On. They'll have some great info for you! I usually make my bucks out of MDF.
@@punishedprops Awesome! I just shot them an email. Thanks for responding!
@@punishedprops One last question...I suspect my shop vac might not be strong enough either. How powerful of a shop vac should I be using for this?
Is there a clear urethane resin for capturing things visible within? Cheers
Absolutely! I'd check out Smooth-On's site and ask their customer service which material they'd recommend - they're super helpful
Show us your cans next!
Can this stuff be used on cardboard or paper mache clay??
What is the cost for a raw wearable cast helmet? Also : What is the cheapest stuff to cast a wearable helmet?
Will urethane stick to silicone or to acrylic, I want to make a 2 part mold to cast silicone parts
A common material for casting silicone parts is an epoxy/fiberglass mold. We haven't done one yet, but that's how they do it at Immortal Masks: ua-cam.com/video/NVws0ryS3-E/v-deo.html
Hi, can you let me know what kind of resin that will be like ABS plastic after it dries?
Most resins are quite hard once cured, it'll just take some experimenting to figure out which one you like best
Hey bill could you do a video on smooth cast 57D I'm having issues with it and I'm hoping you can help me
I would contact the folks at Smooth-On! They're really awesome at responding quickly and helping with their materials
so im looking for a resin that when its dried ends up with a similar look to frosted plexiglass do you have any idea where i could find that?
I would ask the people at Smooth-On.com. The would know.
I would like used as the binding agent for the material
can I make a polyurethane slush casting from mold I have of my head and then fill that hollow cast with plaster to add weight?
Punished Props thank you so much for the quick reply and I need the outer part made if plastic for my class but I just like the extra weight plaster fives. thank you for the reply.
Any clue what's the best polyurethane to make skateboard wheels?
Hmmm that I'm not sure. I would recommend getting a hold of Smooth-On customer service and asking them! They're super helpful.
Is there something like nylon resin?
Can you cast urethane to cured urethane or would you need to use adhesive ?
Once the urethane has fully cured a fresh batch of urethane will not fully bond to it. You can sand the surface of the cured urethane to get them to stick together better, but it would be best to let everything fully cure and then glue the parts together.
@@punishedprops cheers :)
Can this be used to make a speed bag ball hook swivel or is it too soft
I think you'd want metal for something like that
I like your hat bro.
Instead of adding a dye could I just paint it afterwards
