Dice Cap Molds- No pressure pot required! 

The little hint of a kitty watching just as intently as we are was positively charming

I got a little over excited trying to get into dice making and didn't realize that a lot of the stuff I bought was dependent on using a pressure pot and I got very discouraged, very quickly. So this video is an absolute life saver and I am so excited to try again at making my own! Thank you so much!!

I've found a way to keep the Let's Resin silicone liquid long enough for it to release all the bubbles without using a pressure pot! I put my silicone in the fridge for 30-60 minutes before I begin working, then I mix the silicone, pour the mold, and put the whole thing back in the fridge to de-gas for another 30-60 minutes before removing it and letting it cure as normal. It's legit magic to come back and see the mold come out of the fridge completely bubble-free and still liquid. I've also done small-scale tests and managed to keep the silicone liquid in the fridge for over 3 hours! I also didn't mix slowly and ALL of the bubbles were released from my small sample batch within 30 minutes. The next time I make molds I'm going to let the silicone de-gas in the fridge after mixing and before pouring the mold, then again after pouring the mold to attempt to reduce the chance of bubbles around the numbers even more. I didn't have any issues with bubbles in the numbers last time using your pre-treatment method, but it's a lot of work (as you said) and I want to see if the fridge method works just as well.

You gave me hope to make a nice dice without a pressure pot! Thank you very much, it's a great wideo ❤️

I watched this video, then I purchased everything to do this. Totally had you within reach while making this mold! It worked, the mold is amazing and I know you made this awhile ago but God thank you thank you so much for making and sharing. All this so I could hand make a dice set for my bf and anyone else in the group who'd like a pair! Lol!! ❤️❤️❤️

Never apologize for cat. Excellent tutorial, thank you for creating!

I have always been nervous about making dice because it uses chemicals and pressure pots can be dangerous. This video eased my nerves and I am preparing the materials to make my first dice set! Thanks!

I was very iffy about trying my hand at dice making but honestly this is probably the best how to on how to make your own molds I've come across and I am excited to try it now. Between what I've seen from you and rybonator I'm certain I can come up with something good!!

Hey I used your technique to make my own dice! They came out awesome, but my main problem is im really bad at sanding down the side with all the extra resin from the mold. Ended up ruining that side :(. Have you thought about making a sanding and polishing video? Would love to see your technique.

I just made my first set of dice with cap molds before watching this video. Lot of bubbles and I wasn't happy with how they sealed. This video was very informative and I'm confident that I can make a slab mold myself now!

Oh my gosh I'm so happy to have come across this! I just started getting into resin and really want to make dice but I was panicking when I saw all the makers using pressure pots. I can't afford that right now so, this is SO helpful thank you so much!

ball bearings are good for mold keys but you are the video expert shower I'm just the new year's eve drinker.

A very well done tutorial. Having made molds, of all types, I was thinking wouldn't it save time if instead of separate tape and large tape tape base, you did the three tape base and stick the dice directly to that. You can test fit before laying tape and mark the dice positions on the paper.

Can I just say that I love you? Lol... but seriously, thank you! This is brilliant and so helpful to those that don't have the finances to buy all the fancy equipment. I can now make my D&D group their own character dice ♡

This was fantastically informative. I've been wanting to make dice for a while. I'm glad there is a way to do it without a vacuum chamber setup and a pressure pot. I wasn't looking to invest a lot to get started.

your videos are just amazing!! i'm searching on how to make molds for rpg dice set for a week now and let me tell u someting.... i've learned A LOT more in your videos than the other more views. Thanks a lot for sharing your exp with us!!

I've been wanting to make dice for so long now, I have everything I need already but I've always put it off because of the molds and this video helps a lot more than other's I've seen. Also I had no idea that chessex dice designs were copyrighted and unsellable and that's really useful info cause I was totally planning on doing that! So thank you very much!

Thank you for this video! :-) I just wanna share a few tips I have on this after doing various techniques and arriving at what works for me: - You can use the top of a spray can if you don't have any fittings. Yes, getting fittings is for sure best, but I got that urge to create that MUST be scratched on a day where the stores were closed. So lids from spray paint or, in my case, lighter gas cannisters, works well too. They're even flexible to help with removal. - I have had the same issue with not being able to visually tell when my silicone is mixed. I fixed this by adding alcohol dye, though it dawned on me after that powder pigment might work better. I now have one pink and one green! And as you can dye silicone anyway, this doesn't seem to impact the final product. The only downside is that you no longer have the colourless silicone, so if you do more than just moulds with your silicone where colour might matter, this is not a good way to do it. But I like it - If your silicone arrives in big jugs instead of convenient bottles(like mine did), bakers and cake decorators use these sort of "condiment bottles" often for decoratively running lines of chocolare or whatever over your food. If you cut the tip off of these to make the hole slightly larger, they work amazingly for dosing silicone

I wanted to say thank you so much for sharing this process. I really wanted to get into making dice but I lack room and cash for pressure pots and vacuum chambers (maybe someday though if I really get into it) and I just tried this method out to make my first slab mold. It's winter where I am and its a pretty dry cold so I found putting my mold out on the porch for about 45-60 minutes right after pouring the silicone also helped reduced the bubbles a lot though it extended the time it took to cure once I brought it back inside. I got little nervous that things wouldn't turn out but it all worked out in the end. Now I can't wait to get to pouring some resin in my brand new mold. :D

This is so informative! My first set of molds was quite full of bubbles on numbers and the work time was so short! Next time I'll follow your instructions, thank you so much for this!

I usually use a pressure pot for making my moulds but this video has a lot of useful info to making great moulds. Thanks for the great information 😁

This is a very informative video and I really like the way you explain each step. This method is way better than the molds you buy from Wish and Amazon. Don't get me wrong, they make really good chocolate and candy molds.

I just did a mold like it is shown in this video and I have to say: THANKS a lot! THe silicone rubber ist just perfectly bubble free and my dice came out perfectly shine and I have to do almost nothing for a finish. It is so good and I really recommend investing a little in the silicone as it is not the cheapest, but it definitely pays off. I started off using the well know cheap dice mold with the little whole in the top - you guy know which I mean - and i had to do a lot to the dice afterwards or do a several step pouring. This cost time and is really not as satifying but rather disappointing. In this case i just made the dice in one pour and i am really happy with the results. Thanks so much for sharing this with us and showing a step by step tutorial. I am so happy, I found the video. :)

Absolutely fantastic!! I'm not new to making molds, but I am new to making molds of 3D objects. This is a lifesaver!!

Thank you for turning me onto Arcana Cast. I'm looking forward to buying some masters soon.

My mom bought me molds off wish so I don't know much about them but I am gonna try all this cause I don't have a pot so thankyou much love 💕

Thank you so so so much for this video!!!! I made my first cap mold with this video and it came out absolutely perfect

I've been using Let's Resin and it works really well amd I'm brand new to the scene.

Wonderful video! Clear explanations and images, and I really appreciate all the detail. Looking forward to giving this a try!

This an awesome video! I want to make dice for my son for Christmas, and after watching so many videos THIS is the one I will use!! It is so clear, and your technique is fantastic. Thank you for taking the time to share! Happy Holidays!! (of course now I have to look at your other videos hahaha)

I was using PVC pipe or connectors for a long time for making 8", 6", 4", 2" and 1.25" molds pretty much doing exactly as you are doing with creating a new bottom and hot gluing it on to the each time. As I got busier and was producing more and more molds this added a great deal of extra time that added up to a good bit of what seemed like time I was wasting simply making new bottom seals for the mold. In the hardware store on day picking up another length of PVC for cutting to length for how deep I wanted my molds I stumbled on a sales bin where the were getting rid of old stock PVC end caps that come in the same dimensions of pipe I use. The caps are more then sufficient in height for my molds and the upside was since it was a cap to terminate the pipe, it came with a bottom that was all part of the cap so not huge messes as there is no way it can spring a leak unless you drill a hole in it. You can make both the mold itself and the cap in it, just using different depths of the silicone. I do use a mold release product that I apply a good spray of after I remove a mold and clean the cap, let it dry with the open end down so the mold release stays well and ready for next use. I like to use a mold release if I have fine detail in the face I pretreat with silicone as you do, not just the numbers but engraved areas for the style of dice I am making. Those areas are always fragile and nothing is so depressing as to remove several die or jewelry items from the hardened silicone and have even just one small ridge, number or detail tear away because it stuck to the Item I was making the mold from, or no matter how carefully you check to make sure the PVC is still shiny and the mold tears as it sticks to the PVC when removing it, its not a mold one can then sell. Using the PVC cap also gives a much more professional look to a finished mold without spending time time having to clean up where the pipe was hot glued to the parchment and tape or cellophane for the bottom. And you not going to have a nasty surprise when you come to check the mold some time later and a slow leak, not noticeable at first, has leaked out 25% of your silicone and part of what you are trying to copy has no longer covered in the original silicone pour, and you may have bubbles that have invaded at the leak point and your mold is probbaly not salvageable except for your own use. Using the caps has really cut down my loss of product, which can be costly, buy eliminating leaks from the mold bottom

Thank you! I want to make my own dice but I felt so discouraged bc I can't get a pressure pot rn. Excited to try it after watching your video

This gave me hope on making my own molds for resin art!!

I have watched a few of your videos about dice making without pressure pot. I was about to give up on my dream of making my own dice because a pressure pot is way out of my reach at this moment, but because of your video's and your tips I am ready to give it a try :) A friend of mine will print my own designed dice and from there I'll use your methods of getting molds (without cure inhibition I hope) and dice. So massive thank you!!

I always had trouble with my numbers so gonna try that tip

Really excellent tutorial! Thank you!

Fantastic video and explanation, exactly what I needed to see to give me the confidence to give dice making a try!

Pixiss Silicone works great. I have used it for all of my molds with no pressure pot and no bubble issues.

I have watched so many videos and yours is fantastic. I often wondered about doing the technique you did, pre swabbing them. I also had wondered about doing it with the resin. Anyway, you did a fantastic job with this video.

This was the most helpful video. Thank you.

In regard to the use of keys, it makes sense to leave a few cabochons in there so they too become molds for more cabochons from excess resin when forming the cap, i like that you have lots of keys and just see that some are possible additional places to use resin, moreso if its a color mix you really like.

This is such a great video. Thanks so much! Great detail! Ready to make another mold!

Great video. It's interesting to hear about the 3D printing option. The big thing I wonder with that is the horizontal lines that come with all printed objects. Note: I'm just interested in learning the processes for making dice. I'm most likely not going to get into the hobby myself. Short of winning a small lottery.

Good tutorial, though if I could impart one lil bit of advice; When pouring the silicone into the cast, you're correct it's important to pour from a high stream, but also consider pouring it from one spot (not moving it around everywhere). Moving the stream around whilst slowly pouring things can also trap air bubbles, so it's advised to simply pour in one spot, and simple let the silicone slowly creep and fill in the entire area (preferably away from any of the molds themselves).

Wow i didn't know this was possible, i will attempt to make my own molds with your technique, thank you for the tutorial!

Wow these videos are really good and informative. Can't wait to see sanding and finishing.

Oh I totally need to try this

This was a really great video. But I need to give a gigantic thanks for linking the testing video by Richard Thompson. I've been looking for months for a video just like this one and despite searching all the words used in the title I was never given this video in my results. So yeah, thanks a bunch for referencing that because it's been mighty helpful :)

hi, can you possibly link to the silicone and where to get the dice masters? great video!!! ty

WOW, this looks great!!! You are so informative for these molds. I just recently started using Zona papers for sanding my dominos. Do you notice a huge difference between dry sanding and wet sanding? I noticed that although the zona does a great job, I can never get close to the original resin flawless finish by dry sanding by using all the different papers.

really really good Tutorial, You have a nice voice to listen to and your Videos are well structured. Well made I hope you will make more Videos soon and keep on doing :)

This is super helpful! You mention having read the MSDS for the Let's Resin silicone, but I can't find it on their website. Do you have a link to it?

Thank you! This was a great tutorial

What the heck why would someone thumbs down such a clear and concise video. Excellent work now I have a new idea how to make my molds.

I've had good luck using the smooth on slow 15 ...pot about 50 minute work time and 4 hr set up... I cast small things in it, so it can reach into corners well and smaller Impressions... I was curious about the let's resin so good to know!

Really good video, thanks!

do you have to clean the petroleum jelly off after separating the lid?

Not planning on making dice anytime soon, but I want to make little resin doll parts and I'd like to make a mold out of them so I can make multiple dolls - but I don't have a pressure pot. This gives me hope that I could apply these techniques to put together a mold that can work easily for multiple dolls. (I've been trying to use Mold Maker Putty to make my molds, but that's been a struggle for me and it'd be nicer to make molds with something pourable.)

Ya know, there is this "new" product out there called "a self-healing cutting mat" which probably would be sooooooo much better than your non-self healing fingers!!! Safety first!!! Aside from that, I love your video, thank you so much for sharing! Cheers!!!

This is just what I needed thank you!! :D

I'm curious if you ever used something that's "door knob" shape so it would actually lock into place as opposed to just a round ball?

Love your videos and your dice looked awesome. What do you use to polish?

What do you use to clean the Vaseline off of the mold?

Hi! This is a great video! I started doing my own. Quick question: the consistency seems a bit runny and runs off the numbers. How do you keep it from doing so? Is there a way to thicken it? Thanks!

With the silicone-ing of the numbers: have you ever had it that the number did not peel away from the die as intended? Also now you’ve had a chance to use both your single molds and one giant one, do you have a preference? I super appreciate your your videos. Gives hope to the common hobbiest. Thanks!

A tip for trimming the tape @ 11:00 Just use scissors instead of an xacto knife. Kind of a duh moment there. The only problem you might have with using scissors to cut tape is an eventual build up of sticky residue on the blades, but that's easy to clean off with some acetone, and really barely an inconvenience compared to slicing open your hand with an xacto.

I wanna see how these came out when you used them!

Your nails looks so great and beauty)

You should never apologize for a cat nose! :-D xoxo

How many pulls do you generally get with the Let's Resin molds vs the other brand you mentioned?

I've done the bottom so far and I'm waiting for more silicone to finish the top. If I notice a bubble or two on the top near the embedded dice, will those hopefully fill up when I do the top as long as I don't coat them with the petroleum jelly?

So which dice could be used for selling? I would like to start my own etsy shop, but I am not sure what dice master to use. Thank you for the video

I haven't seen any videos of dice makers trying this, I suppose it's harder to make but... Have you considered doing 'half and half' style molds for dice so that the profile is split in half, you join the molds, pour from the top and once the resin is cured you separate the halves and the die is easier to pull out?

Thank you for this video. It gave me hope for making molds without pressure pots. Also have you tried putting Vaseline on the inside of the pvc pipe for the bottom or would that not work because it's not solidified yet?

Great video thanks

Hi, just me again . . . just noticed, you're doing this on your beige carpet, Brave girl to say the least!!!!!!

Hey, I found some mold making stuff at Hobby Lobby called Amazing Remelt. I was wondering if you could do a review on this and give your opinion? Thanks!

I can now feed my hidden dice goblin at fraction of the cost.

"Kid legos" SO there are adult legos. Sickkkkkkkk

So I just got a set of masterdice finished sanding and them and getting them nice and pretty for casting molds. Then I use the lets resin silicone and followed this method and had to stop after covering the numbers in silicone. For some reason the silicone is not curing wherever it touches the dice. Any ideas what might be happening? It cures wherever it pools around the dice but won’t no matter how long I let it sit on the dice. 😩

can you make keys with hot glue? like, obviously not durning but ahead of time?

Do you have any suggestions on where to get dice masters? Or are yours 100% customized from a commissioner

Could I hot glue or somehow tape some toothpicks on the master dice to make sprues so I don't have to fiddle with a blank side?

Hi, any reason why you didn't use scissors for the tape? That exacto knife section was terrifying to watch haha. Great video btw :)

could I use some kind of plastic container instead of the pvc? also can I just cut the keys in the sides instead of all the internal keys?

Would you ever sell your molds I can find resin in my area but I can’t find silicone but I love your work

Ive attempted to make molds with this stuff and fail both times. Ive tried weighing them evenly and keepin it at 75 in my apartment. Ive tried different containers and stirring tons and tons… Any suggestion?

So I used this method, I am making dice for the first time. The mold came out perfectly thx to this amazing video! But when I put the cap on, it sometimes creates bubbles on the edges of some of the dice/epoxy. Any tips on that?

I loved the video! And am planning on making a mold as well. However I want to use metal dice as my masters. Is this a problem?

Is there any issue using a silicone mold in a pressure pot that wasn’t pressure treated before hand? Can you just fill this with resin and not get air bubbles in the finished dice if you don’t put it in a pressure pot?

Have you tried any other brands of silicone for making molds without a pressure pot? Ive been using the Alumilite Mold Maker silicone that I can get at my local hobby/craft store. Any other suggestions?

This also gives me hope to some day make my own molds. It's just coming up with the masters. Ever consider making and selling your molds for those of us who cant well, acquire everything? Everywhere I see for molds sell them for like 30-50+ for a single dice. It's just... damn. I'd have thought such would = the cost of the silicone + time or something.. not... breaking bank. I can see why they say its cheaper to make your own. The only issue I'm finding really is getting the masters to even start such a project and those cost even more than the pre-made molds for a single dice again. Do you know of any other dice sets out there that are generic that could be used as masters? Or you know, sell your own mold sets (hopefully at reasonable price) but thats wishful thinking :3

Thank you so much for your tutorial! I had a question. Do you know if we don't have a pressure pot, if we could just use a pressure cooker? I'll still try this method, without a pressure pot, though.

I'm new to making dice and would like to try and sell them. What would be the best way to get a set of master dice?

My numbers stayed in masters 😭 Do I have to just start it all over again?

Where can I get the molds from great job

Are you trying to keep or reapply petroleum between the top and bottom mold sections when using them? Or can you now wipe them clean and they're good to go?

As someone who can't afford masters, I'd really like to know what exactly about chessex dice is copyrighted. The shape? The font of the numbers?

Sadly i have been having extreme troubles with cure inhibition using this method. Let me share my troubles that it might help someone else, or maybe someone has ideas for me I have poured this three times now. The first time the numbers came out well except on a few dice with especially small numbers. I thought I was a little too rough maybe. Or it could have been that I waited almost 3 days for it to cure. The second time, one of the dice was completely covered in uncured silicone, the rest had some residue on several faces. I read up on the cure inhibitors. Some things I was using that cause cure inhibition are - nitrilite gloves - wood stir sticks - wood toothpicks Another detail I found was that sometimes silicone doesn’t cure well if you stir less than 30g of it (which I had been doing batches of 15g or so) Another detail was that thin layers of silicone don’t always cure (I guess not enough reaction) The big deal in my second pour what the nitrilite gloves. I eliminated them. The third try I got rid of the gloves, used a butter knife to stir the silicone, and in the video you use a toothpick so I kept the toothpick not thinking much of it. After waiting a full day the numbers still showed cure inhibition so I looked it up, some advice was to put the dice in sunlight. After several hours of sunlight and a full day there was still inhibition. After another day of 10 hours of sunlight and 6 more hours, it was cured on most sides. I poured step 2 and 3, hopeful that it would help the thinner parts to cure. Every one of them came out completely covered in uncured goo and none of the numbers cured. On my fourth try I will be - using a plastic knife to stir and a plastic dental pick, eliminating all possibility that this is the problem. - cleaning the dice with alcohol - buff with the 1 micron paper - scrub debris with a soft bristled plastic brush and water Just to be clear, other rules I have followed (so no one thinks I might have done something else wrong) - I stir for 5 to 5.5 minutes - I pull the bubbles out in a vacuum chamber for 5~ minutes - I use a scale - I use a plastic cup - I’m using packing tape - The house is between 68-72 degrees - I’m using the set of dice from arcana cast - I’m using the silicone sold by let’s resin (I bought the same bottles for the first two tries then ran out, so I bought the bigger bottles with the squid photo for tries number 3 and now 4.) I’ll let you know how it goes...

I just ordered some Let's Resin silicone to make some dice molds! Is it possible to add mica powder to the mix to color the silicone? My thought being that it'd make it slightly easier to see where to put the jelly.
