There are 3 different ways you can make dice molds. You can have an open face mold (the lowest quality, but easiest to make). A squish mold (a lot of people prefer this style), or a sprue mold, like we make in this video. I prefer the sprue method, as I think it is a good mixture of ease of use, and ease of cleanup. If there is enough desire, I'm happy to show how to make the other two in a future video!

With my last molds, sanding was a nightmare, and because i dont have the right sanding and polishing paper, it takes me more than an hour to sand just 3 dice!! This is amazing, thanks!!

Instead of a straight cut, I use a zig zag to help the parts of my mold register better and prevent any shearing.

[@rosemali3022]

Do you put the dice molds in the fridge before or after filling?

[@juliestevens2894]

I use hot glue and a cut straw as a sprue, and I hot glue at a corner :) It makes it so you don't need a dremel (*edit good point on the sanding, that part actually DOES make you want to have a dremel....) and, it makes a wider opening for pouring. I really love the idea of using another dice for the funnel space.

[@jamessheppard1606]

Something you could add, not sure if you talked about it already, is the paint on the dice numbers. I made a mold, used a pressure pot, and it turned out awesome. But when cleaning and polishing the die some of the number faces where not deep enough and the number was half gone. So I used acetone to clean the numbers of paint and made a new mold. Not a problem any more.

[@Okoranasan]

I was wondering if you'd be able to try a specific silicone? I've been eyeing Castaldo LiquaGlass, but I don't want to try it and then not have it work.

[@bmg963]

If you don’t have a pressure tank, all you need to do is stir the mixture slowly to avoid the bubbles all together. Great video! Thank you, as I was just looking into this!

I used to do it without a pressure pot, it's just such a foolproof method. But yes! Stirring slowly absolutely helps :)

"I got my holes ready to go" -- Rybonator, 2020

[@brandonwarner8450]

Thanks for making this channel, I got into resin casting, pretty much inspired by the desire to make my own gamer dice so I greatly appreciate it. You do a fantastic job with the channel in general, however, I did notice one small thing that I would want to correct/adjust if I were you. At one point you advise us to try to make perfectly straight smooth cuts when cutting our block mold's parting/demolding splits. Based on expert advice from a seasoned casting & mold making professional (see Robert Tolone's channel), my understanding is that this advice is only partially true/advisable. While you do typically want generally straight cut lines right next to the original, generally that is the only place you want them to be perfectly straight. Right next to the part you are casting, this is done in order to minimize the length and appearance of seem lines and therefor minimize the finishing work you will have to do. Also, you may want to place them strategically based on the original. Besides the cuts that are right next to the original (say within 1/8 to 1/4 inch away from the surface of the original), what you really want to do is make your cuts somewhat jagged (within reason), making slight random left/right movements as you cut from top to bottom, so that the two sides along the split fit together like little teeth, locking the mold back together in the exactly correct position. It is the same idea or purpose as making the registration keys you would make on a two-part mold. Instead of having two flat surfaces coming together which can easily slip, slide, or otherwise become misaligned where the sections of split mold meet, you have a unique jagged surface on one side, which perfectly fits into the jagged surface on the other side, ONLY when the sides are perfectly aligned. If they are misaligned a little, the surfaces will help guide them to the correct position, and they will lock into place.

[@jillinine8334]

Hello, love the video! I have a question, do you need to have a pressure pot to get rid of silicone bubbles? Are there any other techniques to get rid of them? Also do the bubbles interfere with the mold's quality if you don't put them in a pressure pot? Thanks!

[@megangilstrap1542]

This is a quarantine godsend

[@daniellearmstrong1832]

Thank you for your videos! I love them and they helped me be able to cast my own dice molds! So, I made my first one with clear silicone and it cast pretty well. I did a test pour on it and I just can't seem to get bubbles out. I don't have a pressure pot. The dice came out really nice except the top. It's full if bubbles and even a large one on the corner. I can't seem to figure out how to fill the mold without getting large bubbles in the corners. Any tips?

[@thedemoman88]

Ey, Thanks for posting this. I lost my Warhammer 40k dice, and wanted to see if I could make my own instead of buying those damn $5 packs. It worked! I little bit of residue on the sides, but nothing a small Dremel can’t fix. I did wanted to use Paint on the sides, but I’m terrible with paint materials, so I just used a regular ol’ sharpie.

[@LouNeptune]

Thank you!!!!

[@TetherOnline]

I will add that you should look into what brand of silicone you want to use. I picked up a cheaper silicone molding kit a little bit ago to make test dice sets, thank god I didn't use them for my actual molds, and after a few tests the numbers were pulled out from inside the silicone molds and made them useless....well, useless if you wanted to use the dice I'm still going to use them to test things out anyway. I know living in Canada there's not many companies that sell Silicone, hell more then half of them on Amazon will run you up one hell of a bill for 2 or more sets of molding kits so it's well worth doing the research for what you want.

[@RevolutionaryLiger]

Any suggestions for silicone brands, I'm also in Canada and it's hard to figure out what to get.

[@metracxx]

I feel like silicone is extremely expensive everywhere except america.

[@TetherOnline]

@@metracxx Sadly I agree as well. I think it's because one of the companies I see all the time is based in USA so shipping just costs WAY more then it should.

[@KallaBeccani]

Love this style! Couple of questions. When you went and cut them are you only doing one side? Opposite sides? Or two cuts at a 45-90 degree area? Or does it even matter? I really do love the mixture of the styles between you and DarkMoon. Also will this work with the metal dice or do you think it best to do something different. We just ordered a new Resin printer so I can make some masters if the metal dice cant be done this way I might wait a bit longer and just use the prints. I had a very hard time doing your original way and getting ready to redo molds so this video really comes in helpful.

[@DARKMATAR0610]

Awesome thank you ! Might be a silly question but...how do you clean the silicone from your tools ^^' ?

[@applewatermelon3]

First off, I absolutely LOVE your videos! They're so informative and I'm eternally grateful for you sharing this knowledge. Secondly, what do you use to remove the toothpicks from the mold-dice? I superglued them in there, and even nail polish remover isn't helping to get those suckers out. I haven't cast any resin in them yet, but I'm pretty positive I messed up the length of the toothpick -- made it way too short and not sure if the other face will appear. We'll see!! :)

[@sethkuhn4619]

Do you have any recommendations for doing this toothpick method with a metal master set? Like the one's you showed as an example of corner method.

[@petthepsycopath]

Rybonator Can you make a video on how to make UV resin dice in theses molds? particularly talking about what you would and wouldn't do with UV resin. For example if you would use a pressure pot on UV resin or a particular type of UV resin you like to use over others. I would also love a UV resin comparison to a 2 part resin.

[@vzimmz69]

I usually make little things and charms with UV resin and I wonder how it will work if you try to make dice

[@peevester9987]

Oh yeah, I really like the sprue method, since it doesn't leave that mess on the corner when you glue the dice directly to it. You sacrifice the originals though, so buy a second set to support the maker! Interesting that you use a pressure pot for the silicone - I've always seen this done with a vacuum instead, and there is always a GIANT mess if you fill up the mold as high as you need to here. Since the results are just as good, less messy, and you don't need TWO pressure vessels, this seems like a big win! I am going to have to give this a try, thanks for the patient demo! Have you done a video on 3d printing masters? I'm interested on how you deal with layer lines. EDIT: Ah, I see I missed one from last month, where you used a resin printer, which explains how the quality is sufficient.

[@finleycarroll2208]

I've been having trouble with my molds (made from the turquoise silicone, mold star 15 or something). It was great for awhile and then my dice started getting cloudy, even after paying extra attention to sanding down the sides. After watching this AWESOME video, I think I'm gonna remake my molds because this way looks so much easier and HOLY MOLY sanding takes me two days! Still, is there a way I can fix my old molds to stop making my dice cloudy, or are they just old? (I used it nine or less times, it was barely 2 months old). Anyways, thanks for this awesome video! This channel and the comments inspires me so much, and I will definitely try out this method.

[@jatna77]

Thanks for the vids! What air compressor do you suggest for hooking up to your pressure pot?

[@shnugglebunni]

Great video! I wish my molds would work like yours. I seem to be coming across an issue with my dice coming out the molds slimy *mostly the numbers are slimy* I've got no idea what to do. I've let it sit in the pressure pot for well over 12 hours and didn't cut it open until 20 hours later 🙃 any advice on what I should do? Thank you in advance! 😊

[@violentcrumble6720]

so thank you for this method! i just make my first dice molds! However! It seems that the resin has trouble finding it's way all the down into the die part. I used the thinnest resin i have polyester and still had some cavities! Do you add an air hole or what is your process for pouring the resin in? I pressure casted both the silicon mold and also the resin dice cast. thank you.

[@trueCinemaniac]

Great video! I am just about to get started on my first attempt, but am confused about vacuum chambers versus pressure pots. Some videos I've seen say use a vacuum chamber for making the silicone mold, and pressure pot for the casting. But you mentioned pressure pot can be used instead of vacuum chamber for debubbling the silicone? If so, that'll save me lots of money as I've already broken the bank buying materials. Can you please shed any light on if there is any good reason to get a vacuum chamber, as opposed to using a pressure pot for both molds and casts? Thank you!

[@brendanmiller7228]

Hello! I was wondering how much of the sorta-clear would I need to make 1 set of dice molds? Would the 2 lbs of it be enough?

[@jushpubby]

4:05 Dice popsicles are a cool idea (pun intended). you could make molds with food safe silicone and use different juices and drink mixes to make edible dice. but it'd probably work better with a flat image of a die, small dice wouldn't be much of a popsicle and big dice would be hard to eat.

[@lukelaw13ll]

You've inspired me to make my own dice, but I've been wondering; roughly how many molds can be made from one batch of silicone?

[@codyPSP]

Hey man. Love your videos. For a little clarity if you have the time: did you leave the molds in the pressurized pressure pot for 12 hours, or take them out after a few minutes at pressure?

[@ariaa-s5180]

Not gonna lie, I died a little bit when he drilled the die.

Cheers and thank you for all the videos!

[@Necroxin]

Edit: Just saw your video about my question, so no worries! This comes out just as I'm getting all the final pieces for my pressure pot, lol! Quick question then: do you no longer use the vacuum chamber for silicone? I was looking at buying one here in the next few days, but if it's just fine using the pressure pot, I'm gonna save the extra for resin and silicone supplies!
