i made a mold and learned a thing i should have already known. if you put your mold away to cure, make sure that you put it on a level surface.
My mold is usable, but i need to make sure to angle it a bit to make it level.
I learned a lot of these techniques in art school but these videos are so helpful as a refresher and learning new info and tips I didn't know even after doing this for a while. Thanks!!
This is why i love UA-cam! :D
All this free, professionally shot educational content that is very well explained and easy to understand.
Thanks! And keep up the great work!
Fantastic tutorial Bill!! Informative & entertaining.......just how it should be!! Thank you so much for sharing!!
Fantastic video. I just noticed that your degassing chamber looks home-made! If you ever felt like it, I'd love to see a quick show-and-tell video about how it works and how you built it.
Omg dude this is just what i need! Thank you so much for this series. I just started sculpting and i dont want to sell this nice piece i made so now i can start trying to replicate on my own. You changed my life :)
Awesome! I'll definitely be trying this! For estimating the volume of your smaller masters, ever considered dumping it in a graduated measuring jar with a known volume of water and measuring the difference in volume after it is submerged? That should give you a quite accurate measurement.
Love your Tutorials!
Excellent tutorial, just what I needed!
He is a great teacher.
great video, well put together and informative
Great tutorial, thanks for putting this together!
Always happy to inform!
really nice for beginners. step-by-step, with corresponding video
Great video, as usual. But I was very distracted by the nice, new work shirt you were wearing! So fancy! :)
Cool video, thanks!
I use lego's to make mould boxes for small pieces. Works great
Is it just me or is Bill slowling turning into Frank? The beard and hat. Will this be Bills final form. hehehehe. Thanks for the video Bill. Making a mold is one of my years goals. Keep up the good videos.
Will you be a Prop: Shop episode for molding helmets?
thank you so much for this video! super helpful
+kat p You're welcome!
Thank you sir.
Very cool!!!!
Thanks. very clear and informative
Happy to help!
nice video! ive seen a lot of mold making videos last year, defintly something i want to go into this year.... have some screen used "elysium" props laying around and some other stuff worth making molds of.
This is super helpful. I have been 3D printing figures from games and anime and I have been trying to find a way to make a mold of them to try some casts and create multiple copies without using all the extra time wasted on waiting for prints.
What would be your suggestion for mold material and casting material?
would a quick hit with a blow torch pop surface bubbles? the same way it works for epoxy?!?
Nice video 😀
Thanks for watching!
For the Q&A video: how do you made that beautiful magic cutting tool used to regristration? Great channel! +Bill Doran I learn something new with each video.
There's no politics, no religious commentary, just someone being creative and friendly.
I'm starting to see your channel like Gandalf sees Hobbiton. It's a place I can come to and relax and let my guard down ... and just ... be.
We're so glad you enjoy our content!
Awesome video!
How do you know what quantity of resin you have to pour into your mold? Especially for manual rotocasting?
Amazing. I've never mold / casted anything right now that I saw few of your last videos I'm going to try for sure! The only problem is that we don't have any Smooth-On materials around here :S
Hi! thanks for the awesome video! I was wondering though, I am making Eris Morn and am trying to figure out her eyes. I decided to use resin for her eyes and possibly her orb, but how would I do a negative cast for her eyes? I don't want a solid piece and haven't figured it out yet.
Thanks!
Great idea to have the German language shown in the subtitle. that's really special. I would be very happy about videos about multi-part forms from gfk. greetings from Germany
Thanks for watching!
Have you tried using your degasser on the resin in the mold?
great tutorial, if anyone knows can you pour silicone over foam props or will it just absorb them like the blob.
These videos are a real help, I wouldn't know what to do.
Here's my question: Is it possible to cure resin inside of resin that has been rotocasted? Does it depend on the type of resin being used or will the heat damage the resin that has already been cured regardless?
this with the vacume form is going to help me out. casue hand filing metal grips for the gun i did was about 6 hours of misery pain, and blisters..but i got the handel on, made a electric tape mold to make the center part of the grip. but i am not going to put time frames on when i will have the video up cause this took 2 days longer than i though.
Hello,
I just found this channel and is wonderful because it answers the questions the others don’t. I am new to mold making and need to create round mold trays for resin casting but I am not sure how to go about it. How would I create a mold that will give me a border and also how do you create molds with lip in them. Do you have a video I can watch or any suggestions would be greatly appreciated. I am sure a lot of viewers would love to see this process. Thank you
helpful, thanks. was wondering which silicones and resins you use
Congratulario for the video. I would like to make molds for plastic injection. What material do you sugest to mold for plastic injection parts? Thank you for your help.
What type of sculpting material would you recommend using when creating a piece to cast? I've heard that oil based pottery clay could work but maybe there could be a better material.
+Bill Doran Could you make one for helmet molding/casting?
Can you use a vibratory source to remove bubbles like they do for concrete or large molds?
Awesome man!! These movies are very helpful!! Look forward to seeing more content! 😊
what was the long, shaped, gray 2x2 that gets shown at 1:12 used for?
i ask because i have been getting into making custom stilts lately.
Hey Bill, I want to be A prop maker like yourself, I was wondering on what minors and majors I should take when and if I should go to college thanks. But yah a light saber would be sweat whether it's foam or a casting it would be awesome.
Really nice series! What vacuum pump do you use?
Question: Say i made a Foam Gun (made from floor mats) and wanted to make a Mold out of it, is it possible or would the silicone not like the Foam?
Re getting rid of bubbles, if you've got an old HiFi speaker (many are taken to dumps/recycle centres so easy to get for nothing) could you not make a platform that vibrates the mold encouraging the bubbles to rise to the surface?
hey just asking about this, I saw his slush casting video and his other molding video for masks and the stuff he uses is kind of expensive for me, how much can you actually make with this? will one set of this stuff last me a couple of molds or will I have to keep buying?
Do you need mold release for the initial silicon mold onto the master?
nice video ;D will you do a video on shell molds? something done with plastipaste...
How would you mold a mask to cover just the front of the face (with a strap to attach at the back)
Oh god, there was a piece of cat hair smack in the middle of my screen and for a moment I couldn't tell whether it was stuck in the back of your mold or on my computer.
Do you have any recommendations on a good size for a starter degassing chamber? I'm probably not looking at working more than a couple quarts of silicone at any given time.
How would you mold and cast something like a life sized skull (no jaw)? but not have resin all the way through because that seems like a lot of resin.
Sorry if this has already been asked but do you have to use any kind of mold release on the master so it does not stick to the silicone?
I've been trying to find a way to make a mold for a coffee mug to use in pewter casting. Can you help me with this?
I'm going to buy a vacuum mold of a 1 to 1 scale of a Ghostbusters Proton Pack. I was wondering what should I use to make that out of
i have a broken power rangers morper i got on ebay (original mighty morpin) but i dont know what its made out of the coin in the middle sounds hollow with a high sound when you tap it. the silver part the actual morpher has a lower tapping sound and the backing all in black is the lowest sounding. Im assuming the whole thing is black as it seems painted as silver also has some bubbles on the bottom and a bit crudely cast on the sides. The coin has a crack in it and its white so overall im really not sure what's all gone into making it. If punished props can help me out or if anybody else knows it would be VERY appreciated
I like you guys
We think you're pretty swell too. =)
Hi! I was wondering if silicon caulk does work properly for this kind of projects
Kaykadem Tsukumi
Personally I would like to use this on some D&D coins I have in mind. Thanks man!
holy crap!!!! super Mario sunshine, best freaking game!!
that cylindrical mold, is that rebound 25 backed with mold max 40? Asking because I've got a bunch of rebound 25 leftover and not quite enough MM40 for a two part mold, wasn't sure if the tin cure MM and platinum cure r25 was compatible.
+Bill Doran thanks for confirming Bill!
hey man, i'm making a spider-man cosplay and for the spider emblems i'm doing it with latex, but my problem is that i dont know how to make the mold ? what technique should i use ?
Im trying to make thorn from destiny by a mold, how would i make the mold without a object to make one?
hi there, love the vids, awesome content! just wanted some advise, I have been looking into molding and casting, I have 3d printed a dark knight armor set, would like to make molds and then cast them. want to use the most relevant materials, any advice please? aslo please note I live in the uk, so I would have to purchase from here. thanks in advance.
You'll probably end up making a lot of brush on molds. I use Rebound 25 silicone for that. You can cast the parts in a variety of resins depending on the qualities you want from the finished pieces. For materials suppliers in the UK, this should help: www.smooth-on.com/distributor-regions/europe/
Thanks for the tips! I have been wanting to try my hand at making a mould . The thing I’m confused about is that I bought the mold star before and mixed it up but then I realized what can I use for a form of something. For example, I want to create a detailed serving tray but what can I use as a form that the silicone won’t stick to?
You can make a mold master out of pretty much anything! Most frequently people use non-sulfur based clay, finished 3D prints, or pieces made from sealed and sanded MDF.
Punished Props Academy Tysm! That answered my question
I'm going to cast transparent resin nerf parts for a project, but if the object has holes in it, can you get the object out without destroying the mold in the process? Maybe a technique for making the actual mold? Seems like it would be hard to extract the master out of the mold without tearing everything.
If I want to make a silicone shoe upper, how do I create the cast and the filler for the center of the cast so that I result in just a even silicone layer that I would use for the shoe. I have an idea but if there is a know way, can you explain how? Thanks.
Thanks, useful but doesn't explain how to create a even layer (about 5mm) that is the main shoe design. I am basically trying to establish if I can create a seamless, all in one look, or if I have to use silicone sheets and cut the shoe pattern out and stick/adhere together (which isn't the goal). So essentially, how they make silicon masks, but to make it thicker and more accurate, if there is a way.
Hey, can the silicone mould used to cast concrete?
Hey Bill! I live in an apartment with a small deck but otherwise no outside area specifically for us. What kind of prop making can I do without a garage type space?
+Bill Doran Nice! Worbla has always interested me so I'll have to look into it soon. If I see you at Cafe Mox again, we can talk shop :)
What's that zig-zaggy knife thing you used to cut the cylindrical mold called? I need one.
Ahhh, smart. thx!
Can you use food colouring to tint the resin or is there a special product to use?? especially curious for casting with clear resin.
I have no idea if food coloring will work. I always just buy the stuff that's meant for the resin.
Hi! What’s the best mold material to use if your finished product is going to be a silicone piece? Would I still use mold max 30?
To cast in silicone you typically want to use a rigid material for your mold. I'd ask the folks at Smooth-On for what they recommend based on your project.
do you guys happen to have a tutorial on how to make a mold for something like a vase that has a hollow middle?
Jen Galli I know it is late, but look up rotation casting or slush casting
If I have to make several copies in silicon rubber from the same original, what material would be best for the mold?
I would ask the folks over at Smooth-On. twitter.com/smoothon
Do you know how to shrink a handprint taken in a clay? And make a mold for a smaller handprint :) thank you
I do not
would Model Magic be suitable to mold?
what if my master is not fully flat but like almost ? like a mando handplate
Can you clean and reuse the buckets for part a and part b silicone? What's the best way to clean the buckets or are they just automatically trashed?.. i tried rinsing them out with water and dish soap and it became a total sticky mess. Can't seem to find any info that the clean up aspect of the smooth-on products. thx!
I do rinse and reuse them! I usually use soap and water and a good scrub - I find it helps a lot if you wipe out excess silicone IMMEDIATELY after pouring with a paper towel and then clean it out. The mixed one you can just let pour and peel it out :)
@@punishedprops thx so much for the response!
have some questions for the Q&A video, how big is TOO big for a mold? what is the biggest mold you have ever made? how big would you be willing to make a mold, and what are the problems with extra large molds?
Hi, how i Can make-up a molde for canopy for car
how would you go about say molding a pla robin or arrow mask?just lay it back side down on clay and mold the top as a one piece mold?
I would go with a brush on mold.
Have you guys done any LARP weapon tutorials?
For all the "resin mixing stuff" you mention you should add, that especially if you are mixing a larger volume of resin you shouldn't do it in a cheap thin plastic cup. The resin will get really hot and actually melt the cup :D
Thank you for your informative videos. I have a question about the containers you use for preparing the silicone. Do you reuse these containers? If so, how do you clean them up?
Where can I purchase the stuff
can you roto cast with clear?
Hi, trying to do the second part of the mold now and facing a problem,
in order to put the mold release into the tiny corner of the molds due
to the shape and form of the parts, and also I had to clean out the clay
from those areas as well, I had to take the parts out from the mold,
and now they don't fit 100% back in!!! what should i do?? should i have
not taken the parts out in the first place?? Please give advice cause i
don't want to throw away the mold.....
Many thanks in advance
Keith
thank you. I think i will have to remold, some of the parts just completely stick out..... may i ask one more thing, sometime the clay would got stuck in tiny places, or when i need to put mold release onto tiny area (I can't get the spray one), what should i do?? many thanks again.
thanks!!!
Do you need to lube the item you're casting so it can be released?
Yes there is a spray called mold-release!
What is the best plastic to mold that is durable and semi flexible for making a kids toy?
Smooth-On's website has a great Compare feature for their material's properties: www.smooth-on.com/compare/ Smooth Cast 57D may be what you're looking for.
I just made my first two molds, it was originally one but i made too much silicone so i made a mold for something else.
Kind of a late reply, not sure if you guys are still watching comments. I seem to recall a video recently, where you mentioned you started using a new smooth-on silicone that prevented bubbles forming, but I can't remember which video :P. Which smooth-on was it?
Mold Max 29NV. Any of the silicones with "NV" stand for "no vacuum," I belive. They're less viscous and easier to mix, which also means the bubbles can escape easier. www.smooth-on.com/products/mold-max-29nv/
Punished Props Academy awesome thank you!
how should I make a nuka cola bottle if I don't have a 3D printer
what if you were casting something hollow, like a mask?
How about casting silicone into a silicone mold. Possible?
How do you dispose of unused resin and silicone? Is it okay to go down the drain?
+Fel Since it is only going to be in a liquid state for a finite time, you will more than likely destroy your plumbing after the silicone or resin fully cures / hardens. Your best bet is to wait until it's set, peel it out of the container and put it in the trash.
Another trick is to calculate exactly how much material you need, and use only that amount. This decreases your cost and waste.
I was curious if you knew of a material that could be used to make armor, something sturdy enough to withstand several impacts. Like in a full contact SCA environment.
+Bill Doran I'm actually studying medieval English sword play and despite steel plate being the best choice, it's very expensive for the right stuff so I have been looking into modern materials as an alternative. Thank you for the suggestions, I will look into them.
sintra plastic
Quick question... What's your opinion on TKOR's proto puddy as an alternative?
We've never tried using proto putty. Normal, RTV silicone has always worked perfectly for us.
@@punishedprops just wondering for less expensive options for younger audiences
So no release agent or baby powder when making the sillicone mold to capture most of the detail? Only use release agent when casting?
Definitely no baby powder for making the mold - it will be embedded in the silicone. I do frequently use a release agent but in this case didn't really need it, as the buck was quite rigid and unlikely to stick.
@@punishedprops Great, thanks for responding, just made my first mold, left it to fully harden till tomorrow. Cheers
@@punishedprops First cast successful after a few failed attempts, it a small bone like a tube and bigger at the end, added a vent path and used a syringe to slowly pour the resin and eliminate the huge bubble that appeared at the middle which caused it to only cast half of the way.
Please make a video on helmets
