Dice Mold Tutorial: Cap Mold

[@Rybonator]

I was trying to find a way to use packing tape to make this way easier, and you nailed it Dice Witchery! I need to give this a shot :)

[@DiceWitchery]

Hey, thanks!! Using the tape makes the mold openings so crisp, it saves so much time in finishing dice!

[@thegreyarea42]

Literally stumbled on to this page haphazardly and couldn't be more stoked for it.

[@DiceWitchery]

Welcome!! Thank you so much!

[@maryfelty6827]

I've been doing a lot of research on dice mold making before I take a crack at it myself and this is one the more impressive and user friendly tutorials that I've seen regarding cap molds. I look forward to your future videos!

[@DiceWitchery]

Thank you so much!

[@maryfelty6827]

You're welcome! May I ask about how much silicone you used in this video?

[@DiceWitchery]

@@maryfelty6827 Depending on your cups, it'll be about 6-8 oz. for the bases, and 3-4 oz. for the caps.

[@LucyValentine]

Omg, can I say thank you, I appreciate how clean and methodical your workflow (and workstation) is. I've been watching other tutorials, and making cap molds seemed super stressful until I saw this video.

[@milliethomas9984]

Love the internal and external keys. Great, thorough video. Thanks!

[@friendlyvoice9720]

Came out really well...wish I could buy a set off you.

[@brasil1989able]

Thanks for posting this! I can’t wait to see what else you make.

[@madlyunique7014]

Excellent tutorial! I hadn't thought to use packing tape in mold making. I'll have to give t a try!

[@sapphirefireorice]

Awesome and helpful video. Thanks!

[@bluemimic2289]

Your video was great. You did an awesome job on it.

[@DiceWitchery]

Thank you so much!!

[@mostergard2012]

This method is so good and I probably would have given up on making dice without this video. You deserve more views and recognition! Haha

[@DiceWitchery]

Thank you so much! I'm so glad this helped you!

[@gemmanoxs6643]

Great job!

[@user-lu9lf8xr9d]

would you still recommend cap molds even if I don’t have a pressure pot?

[@DiceWitchery]

I think if you can get as many bubbles out before you pour, it should be okay.

[@RichFriedeman]

I like cutting the keys in. I've been using clay keys in the first pour, and it's a hassle getting them shaped well. This looks like a much better approach.

[@MythicalFamilyYT]

We loved this!!! Will be doing this ASAP when I can get back to crafting fun stuff!

[@DiceWitchery]

Awesome, thank you!

[@kseniiabondarenko4401]

Thanks a lot, it was very helpful!

[@CatChicas7]

Thank you so much! This tutorial is so helpful!

[@missviennajones]

super helpful, thank you for sharing!

[@ClassicGlamDoll]

Thanks!

[@LostInfernoFireDragon]

When you use the hot glue do you need to have the glue go over the lip of the cup, or do you need to have the glue just go over the edge of the lip of the cup to do the cap mold.

[@DiceWitchery]

Likely the edge, depending on the cup you're using. You want to create a seal between the cup and the tape so no silicone leaks out the bottom.

[@LostInfernoFireDragon]

@@DiceWitchery Thank you so much for the info, and I find the video really awesome.

[@chrisclose8011]

Do you end up with raised edges on the cap or was it that I trimmed a bit too much from the face on the base?

[@DiceWitchery]

Sometimes I will get raised edges if my resin is too close to the end of the pot life and is too thick for the lid to squish. Adding some weight (a couple of washers work great) may help keep that from happening.

[@delaneyr.6828]

1) I love this so much! Great tutorial. I think I'll try this with my next set of molds! Thank you so much for sharing! 2) I love all the patterns on your shirts they were super cute! 3) I really loved how the video was edited! Do you mind if I ask what software you are using to edit? I'd like to get back into making videos and this one is really well done!

[@DiceWitchery]

Thank you so much! I used Adobe Premiere Rush to edit this. It was the first time I've edited a video and I'm very happy to report that software was easy to figure out!

[@delaneyr.6828]

@@DiceWitchery you're quite welcome! I really loved the video! And thank you for sharing that- I will look Adobe Premiere Rush up. I used to use premiere pro so it should be pretty familiar. Thanks again!

[@emminaluna9992]

Thanks so much for that tutorial! It helps a lot!

[@xoxoblasian7012]

Does this work without a pressure pot?

[@witchlamb]

is a pressure pot necessary for the silicone? i've made sprue molds without one that seem to have turned out fine, except i screwed up the facing of the d12 and d4 and need to redo them. i was thinking of trying this cap mold method instead, but i haven't gotten a pot yet. also i'm curious why you tint the silicone instead of leaving it clear. for the video? just easier to work with later?

[@DiceWitchery]

A pressure pot is not necessary, but recommended. If you get a pressure pot in the future, you'll need to remake your molds though. Otherwise you'll get dice with "pimply" faces. DS20 is mostly opaque anyways, so why not tint them? I also like being able to tell my mold sets apart and tinting them makes that easy.

[@mathijsbreed]

Great video, definitely going to try this! But I was wondering if it is possible to use mini red shot cups for it instead of the plastic cups? I want to keep the silicone waste to a minimum :)

[@DiceWitchery]

Thank you! I have another video where I now use PVC pipe couplings - much more reusable and uses a bit less silicone. Also, keep in mind if you make the walls of your molds too thin, you'll run the risk of dice warping.

[@CrownofRa]

Is this method recommended for dice that have rounded corners? Also is there a reason you did so many individual moulds instead of a block?

[@DiceWitchery]

You could use rounded edge dice, you just might have more to clean up/cut away at the openings. Doing individual molds vs a slab is pretty much personal preference. Doing them individually is easier for me to get them out.

[@wanderingstar7227]

I'm so grateful, this is exactly what I was looking for. One question, can I still dry without a pressure pot thingy?

[@DiceWitchery]

Yes, although this method is easier with a pressure pot. But if you are careful and can get most of the big bubbles popped, you should do okay.

[@altheajansenvanvuuren824]

From what I can see: let the resin sin in a hot water bath for 30min, pour it slowly, and from higher up in thin strands into the molds

[@torif8531]

This is so cool, would've never thought of the clear packing tape!! I do have a question though: Do you frequently get voids without a reservoir of extra resin??

[@DiceWitchery]

Thank you! And no, the only time I get voids is if I press down too much on the lids. I overfill the molds a little and only press the lid down a bit. That's also why I make thicker lids, let gravity help keep them in place.

[@Girlbrush.Threepwood]

At what pressure do you set your pressure pot? And how much silicone did you use for those 7 molds? I hate wasting materials D: Also, how many sets can you cast with those molds before needing to remake them?

[@DiceWitchery]

My pressure pot is only rated for 50 psi max, so I did these at about 45 psi. When I cast resin I stay under 40 psi. Depending on your cup size, I think it was 6-8 oz for the bases and 3-4 oz for the lids. I haven't had DragonSkin 20 long enough to know its longevity, but I do know it has a higher tensile strength than say SortaClear 12, so my guesstimate is probably 30-40 pulls.

[@Girlbrush.Threepwood]

@@DiceWitchery Awesome, thanks! I can't wait to see what other content you'll share with us :)

[@shanharlmall]

I considered this method for dice instead of the sprue or stacked style. More work and you would need to cast in a channel somewhere but more consistent clean results.

[@jackieeeac]

The packing tape is such a good idea! 😍 also, how much silicone do you mix for each part?

[@DiceWitchery]

Depending on the cups you use, maybe 6-8 oz for the bottom and 4-6 oz for the lids?

[@jackieeeac]

Dice Witchery thank you!! ☺️

[@TheCyclone956]

Can you make a video of you making the dice as well? I would love to see it 😍

[@DiceWitchery]

Yep, it's in the works! 😁

[@mandybeier9936]

Hej. What happen if you don't have a vacuum chamber? Got normal silicone from a local craft shop.

[@mandybeier9936]

Sorry have to correct myself. I got latex from pebeo. Does that to works for resin molds?

[@DiceWitchery]

@@mandybeier9936 I don't think so. You need a 2 part silicone for mold making. And to answer your previous question, you can make molds without a pressure pot or vacuum chamber, you'll just need to be careful with stirring so you don't introduce a lot of bubbles. If you decide to get a pressure pot later, you'll need to remake your molds in the pressure pot, otherwise your dice surface will come out uneven and "pimply."

[@madhatterally1046]

My first one I feel I have to remake the cap because when I place it on it would not stay on fully. So I think the cap needs to be thicker.

[@DiceWitchery]

Definitely having a thick cap helps, then gravity can help keep it in place. Alternately, you can try putting something on the lid to weigh it down, or try flipping your mold upside down.

[@crashtestgremlin7696]

Eventually I'll learn not to cut corners. I just wasted a bunch of silicone because I thought I could do it without the hot glue seal. Great video, I'm just dumb.

[@DiceWitchery]

Thank you! And don't feel bad, I had to learn that the hard way when I was first doing these as well!

[@TheKdayotte]

I tried this using ecoflex 00-30 and clear packing tape. My silocone fused to the tape and I could not get it off at all without destroying the mold. Is it the eco flex or the tape that causes this. I know dragon skin is a lot firmer stuff.

[@DiceWitchery]

I have not used Ecoflex 00-30, so I'm not sure on that one. DragonSkin20 is not super firm, I can pop dice easily out of the molds without cutting. It also has a higher tensile strength, so it doesn't scar easily, and can stretch a lot before tearing.

[@galacticg0at653]

Do you use inhibit x on the dice before u pour the silicone

[@DiceWitchery]

I do not. I've never had a need to use mold release on polished dice. If you're molding raw unpolished masters, baby powder works amazing and is so much cheaper.

[@meganfoster9233]

How many ounces did you use to make the top and bottom half of the molds?

[@DiceWitchery]

I haven't made molds this way in quite a while. I believe it was 12 oz for all the bases and 8 oz for the lids.

[@meganfoster9233]

@@DiceWitchery Thank you so much

[@Hay.Balke1223]

When it comes to a master set does the casting process mess up the dice in any way?

[@DiceWitchery]

I can only attest to the materials I've used, and so far I have had no adverse reactions to my masters. I've had masters professionally 3D printed from Shapeways, and from a home 3D printer, both were still pristine when demolding, and I've used DragonSkin20, SortaClear12, and MoldStar15 Slow (platinum cure silicones). As long as your masters are fully cured, you should have no issues.

[@CerenyaSays]

@@DiceWitchery are your masters SLA?

[@lisadennis3834]

what size cups are you using?

[@DiceWitchery]

3 oz plastic disposable cups!
