Casting your own resin dice at home costs a fraction of what a commissioned set runs. A silicone mold, some epoxy, and a few hours of cure time is all it takes to roll a full polyhedral set by next session.
The mold is what determines edge quality. Sharp cavities produce crisp d4 through d20 faces on the first pour; cheap ones leave rounded corners you’ll spend an hour sanding.
Most kits here cover the standard seven DnD shapes, and some go up to 19 styles for collectors or small-batch sellers.
Roomy cavities also let you embed glitter, dried flowers, or mica swirls inside the resin.

A Closer Look at Every Pick
Cavity sharpness, cavity count, and ease of demolding are the factors that separate a good dice mold from a shelf ornament. The top picks produce clean edges on the first pour with minimal sanding, while lower-ranked options trade finish quality for lower price or specialty shape counts.
Each review below calls out exactly where a mold shines and where it falls short.
1. FUNSHOWCASE Resin Dice Molds Epoxy Casting Kit — Best Overall
Complete FUNSHOWCASE resin dice casting kit with polyhedral molds, ready to pour out of the box.
- Full polyhedral set cavities (d4, d6, d8, d10, d12, d20)
- Complete kit ships with the extras you need for a first pour
- Food-grade silicone, no BPA or phthalate
- Works from freezer to 428°F, dishwasher safe
- Transparent mold lets you see cure progress at a glance
- One cycle yields one set of dice
- The bundled extras push price above mold-only listings
FUNSHOWCASE wins because it’s a complete kit.
You don’t have to think about which resin, what gloves, what release spray, it shows up with the parts you need to start pouring.
The transparent mold is a quiet win. You can actually see the cure progressing, which matters for a first-time caster who doesn’t yet have a gut feel for when a die is ready.
Pop a finished set onto cupcake toppers or mix these with silicone cake molds for a themed board-game birthday.
2. Juanya 19 Styles Polyhedral Dice Molds — Runner Up
19-style polyhedral dice mold set with matching lids that cap the cavity for cleaner resin pours.
- 19 different polyhedral dice styles in one set
- Matching lids reduce bubble exposure during cure
- Stereoscopic cavities yield sharper edges
- Multiple d20s in one pour for prototyping
- Flexible silicone releases dice without chipping
- 19 styles is overkill for a basic DnD set
- Lids add a step to the pour process
Kackaidi’s 19-style polyhedral dice mold set includes lids for each mold, the design feature that lets you pour resin and let it cure without the bubbles that open-mold pours create.
Each mold is etched with clear numbers or letters on every facet for crisp results.
Advanced silicone material has excellent elasticity and tear strength for repeated casting cycles. Each mold and matching lid ships in an individual plastic bag for organized storage.
19 styles is overkill for basic D&D sets where you really only need the standard seven, and lids add steps to the pour process for batch production.
For the standard seven-dice set only, the rank-1 FUNSHOWCASE kit or the rank-7 T-HOT seven-shape set skip the extras.
3. Xiuersty Silicone Casting Molds — Best Value
Budget Xiuersty silicone casting molds for beginners learning to pour their first resin dice.
- Seven cavity shapes for a full set at a ten-dollar price point
- Thick silicone resists tearing across repeated pours
- Non-toxic, dust-proof, and odorless
- Roomy cavities fit crystals, petals, or glitter inclusions
- Rinses clean with warm soapy water
- Budget build leaves seam lines on finished dice
- Fewer cavity shapes than premium casting kits
Ten bucks and you’re casting dice. That’s roughly the price of a decent lunch, and Xiuersty delivers enough quality that you don’t walk away feeling cheated.
The seam line is real, you’ll sand it off, not hide it. But for learning the workflow before committing to a premium mold, this is the one.
4. LET’S RESIN Standard DND Dice Mold
LET'S RESIN standard 7-cavity DND dice mold covering d4 through d20 for a full roleplaying set.
- Standard 7-cavity layout (d4, d6, d8, d10, d10%, d12, d20)
- Stereoscopic cavities with sharper edges than single-face molds
- Smooth interior produces glossy dice surfaces
- Compact enough for a craft desk or travel kit
- Flexible silicone releases without cracking
- Seven cavities only, no duplicates for prototyping
- Standard shapes only, no specialty dice
If all you want is the classic seven dice of a DND set, this is the most focused option in the lineup. No specialty shapes, no fluff.
Good for beginners who don’t need to fill a spreadsheet of cavity types. Pour one set, sand it, move on.
5. Polyhedral Dice Two-Part Mold
Two-part silicone mold for polyhedral dice that bolts together for sharper edges and no seam lines.
- Two-part assembly hides the seam line on finished dice
- Sharper corners than single-cavity molds
- Semi-clear platinum silicone lasts longer than standard rubber
- Handmade construction with uniform cavity quality
- Works with UV and epoxy resins (not urethane)
- Two-part assembly takes longer to set up than single molds
- Clamping is required to prevent leakage during pour
Two-part molds hide the seam line, which is the single biggest cosmetic tell of a home-cast die. If you want dice that look store-bought, this is the category to shop.
The tradeoff is setup time. Clamping the halves before the pour adds a few minutes of fuss that the single-cavity molds skip entirely.
6. LET’S RESIN 19 Styles Resin Dice Molds Set
LET'S RESIN expanded set with 19 dice styles for collectors who want specialty dice beyond standard DnD shapes.
- 12 cavities in the base pack, way more than standard kits
- Glossy interior yields mirror-finish dice surfaces
- Every face includes raised numbers, letters, or punctuation
- Priced well under competitor 19-cavity sets
- Works for commercial runs, not just hobby batches
- Some faces need a light sanding to smooth out distortion
- Specialty shapes are rarely needed in casual play
If you’re casting dice to sell or trade, the 19-style set pays for itself after the first run.
Twelve different shapes in the base pack means you can fill an Etsy listing without switching molds.
LET’S RESIN leans into commercial-grade quality at a hobby price. Every cavity is engraved with numbers, punctuation, or letters so the faces read sharp after the pour.
7. T-HOT Resin Dice Silicone Mold
Budget T-HOT resin silicone dice mold for casual hobbyists on a tight budget.
- Non-toxic, odorless, and transparent material
- Seven cavities covering standard polyhedral sizes
- Non-permeable silicone keeps air bubbles out
- Easy release for beginner-friendly pours
- Low price for a full dice set
- d4 cavity runs slightly oversized relative to other faces
- Best kept out of direct sunlight to prevent yellowing
T-HOT’s seven-shape dice mold set covers the standard D4, D6, D8, D10, D12, D20, and D% polyhedral dice in one bundle.
The high-transparency silicone lets you visually monitor curing progress through the mold walls, the design feature that helps beginners avoid pulling pieces too early.
Reusable durable construction holds up to many casting cycles, and the molds work with epoxy resin plus decorative inclusions like crystals, stones, dry flowers, and glitter.
Tiny pip cavities can trap resin dust between pours, so a careful brush-out before each session keeps pip details crisp.
Cured resin dice need careful demolding to protect the sharp facet edges.
8. Crystal Epoxy Mold
Crystal-clear epoxy mold aimed at creating transparent resin dice with embedded inclusions.
- Crystal-clear mold for transparent resin dice
- Thick and tear-resistant silicone
- Seven cavities at a budget price point
- Clean surface keeps inclusions centered
- Non-toxic, safe for hobby casting
- Clear mold shows every air bubble during cure
- Gentle handling keeps inclusions centered
Nine dollars, seven cavities. That’s the sell.
Crystal Epoxy keeps the price low without cutting cavity count, which is unusual at this end of the market.
The clear mold is honest about its bubbles. You’ll see them form and you’ll know whether to run the pressure pot.
Good training wheels for a first caster.
9. WILLBOND 8 Pcs Dice Resin Molds
Eight-piece WILLBOND dice mold set with 7 standard cavities, food-grade silicone certified for hobby casting.
- Eight transparent cavities with matching lids
- Lids seal off pour holes to cut bubble formation
- Food-grade silicone certified for hobby casting
- Compact footprint for a desk or craft table
- Doubles for pendants and charms beyond dice
- Check that all eight lids arrived, some orders ship short
- Smaller cavity size limits statement dice
WILLBOND’s eight-piece dice mold set includes seven different standard polyhedral types: D4, D6, D8, D10 (00-90), D10 (0-9), D12, and D20.
The food-grade silicone is flexible and tear-resistant for repeated casting use.
DIY experience supports custom dice with glitter, dry flowers, mica powder, or other decorative elements added during the pour. Standard shapes only with no specialty dice included, and the smaller cavity size limits casting of large statement dice for display use.
10. AUSTOR 7-Die DND Dice Set
Pre-made 7-die DND dice set from AUSTOR in flame red and ice blue for players who want to skip casting.
- Full standard DND set (d4, d6, d8, d10, d10%, d12, d20)
- Sharp-edge polyhedral dice with clean numbering
- Flame red and ice blue two-color aesthetic
- Ready to roll out of the box
- Saves the time of casting, sanding, and inking
- Not a mold, you're buying finished dice
- Factory coating takes a couple of washes to clear
AUSTOR’s seven-die DND set ships pre-cast in flame red and ice blue, ready to play out of the box for buyers who want finished dice rather than mold-and-cast supplies.
The sharp-edge polyhedral construction creates corners and depth that mold-cast dice often soften.
Hand-cast from natural resin with gold-foil number details and a PU pouch for storage.
The mold flexes during fills and can produce slightly uneven dice faces.
Buy pre-cast for guaranteed regulation play. Takes a few washes to remove the factory coating before first use.
Basic Dice Making Supplies
Dice making is a complex hobby that requires a lot of raw ingredients and supplies such as resin, vessels, and a vacuum or pressure chamber.
Resin
Some resins take hours to cure while others take just minutes, and one of such is the UV resin, this resin is instantly cured when subjected to a force of 36 W UV, and this saves you a lot of time and energy too.
However, those that take hours to cure almost always exceed your expectations with their beauty and exquisiteness, so it’s up to you to pick what matters more: time or beauty?
Vessels
You need visible measuring cups so that you can get all the proportions right, and you can either opt for disposable plastic cups or durable silicone cups that last for a pretty long time.
You might also need droppers or pipettes to pour into the mold, and these also come in a lot of varieties such as injections, squeezers, or droppers.
Vacuum or Pressure Chamber
If you want to make dice commercially, then your dice must be perfect and that’s where the vacuum or pressure chamber come in, these vacuum or pressure chambers prevent the formation of bubbles that distort your dice and render them ugly.
They mightn’t be that cheap, but they come in handy when you need to produce a lot of dice without compromising on the beauty and elegance of a die.
In the question of a vacuum or pressure chamber, it depends on your preference, if you want to render a bubble existentially negligible, use a pressure chamber, but if you wish to remove all the bubbles, then use a vacuum chamber.
Besides these, you can also use dyes, sandpaper, micro-mesh, paints, silica powder, glitters, dry flowers, and many more.
Frequently Asked Questions
What type of resin works best in silicone dice molds?
Epoxy resin is the most common choice because it cures crystal clear, takes color and pigment well, and self-levels in the cavity for sharper edges on each face. UV resin cures faster but tends to yellow over time and doesn’t always fully cure in thicker sections like a d20, which leaves soft spots inside.
How do I get rid of bubbles in my dice?
Pour resin slowly in a thin stream and tap the mold gently against the table to release trapped air bubbles before they set in place. A pressure pot running at around 40 psi during the first hour of cure is the gold standard for completely bubble-free dice, and most serious dice makers consider it essential equipment.
When should I demold my dice?
Wait at least 24 hours for most epoxy resins, and always check the resin manufacturer’s recommended full cure time before pulling the dice from the mold. Demolding too early leaves soft spots that deform permanently when you handle, sand, or roll them, which ruins the balanced weight distribution you need for fair rolls.
Do I need to sand my dice after demolding?
Most dice need at least some finishing work after they come out of the mold. The sprue or pour spout leaves a raised bump that has to be sanded flush, and matte molds leave a textured surface that you’ll want to polish with progressively finer grits up to about 3000 for a glassy finish.
How long does a silicone dice mold last?
A good quality silicone mold handles 30 to 100 pours before the cavity edges soften and lose sharpness, depending on the resin used and how carefully you demold each time. Using a mold release spray before every pour extends that lifespan significantly and makes clean demolding much easier.
Can I inlay numbers or glitter into my dice?
Yes, add glitter, mica powder, or dried flowers directly to the resin before pouring, and they’ll be suspended throughout the die. For inked numbers, paint pigment into the recessed faces after the dice cure and demold, then wipe the surface with isopropyl alcohol so the number recesses stay filled while the flat faces wipe clean.
Final Thoughts
The FUNSHOWCASE Resin Dice Mold takes the top slot because the kit covers all seven standard polyhedral shapes (d4, d6, d8, d10, d12, d20, percentile) in a single purchase. Sharp cavity edges also produce clean numbered faces without manual cleanup work.
For collectors building dice in batches for friends or sale, the Juanya 19-style runner up adds variation that single-shape kits do not cover. The wider style range pays off if you want a varied set table at conventions or markets.
The same resin casting process works for silicone chess pieces if you want to expand beyond dice.
The Xiuersty Silicone Casting Molds are the value pick when you want to test resin dice making before investing in a full polyhedral kit. Lower count of shapes but the same quality silicone for first-time pours.
For a fully custom dice shape that no kit covers, you can pour your own cavity from silicone molding putty over a master die. That is the path most serious dice makers eventually take when stock kits limit their design options.
