Pillar candles, container candles, resin casts, jewelry — pick a shape (or upload your own), and BuildMyMold builds a professional two-part mold with pour spout, snap-fit alignment, and demold check built right in. No 3D skills. No signup.
If you can melt wax, you can make a mold.
Pillar candle? Resin casting? Jewelry piece? Answer two questions and we set every setting for you — mold style, pour spout, wiggle room, all of it.
Choose a built-in shape (heart, star, gem, hexagon, flower), type custom text for a name candle, or upload any STL file. Watch your mold build itself in real 3D — spin it, open it, look inside.
Download print-ready STL files with pouring tips included. Print tonight, pour tomorrow, sell at your market this weekend.
Everything the expensive CAD tools do — explained in plain English.
One tap paints trouble spots red before you waste a print. Catch undercuts and stuck shapes before pouring wax or resin.
See exactly how much wax or resin each cast needs — and what it costs — before you print.
All the 3D magic happens on your device. Your candle and resin designs are never uploaded anywhere.
Alignment bumps are added automatically so your mold halves click together perfectly — no leaks, no misalignment.
Every two-part mold includes a pour spout funnel so your wax or resin goes in clean with zero mess.
Type a name for instant letter mold candles — perfect for custom orders, weddings, and gifts.
Design your candle mold on your phone, print from your desk. The whole studio works on mobile.
Save your project file and pick up exactly where you left off — shape, settings, and all.
Even on the free plan, your STL files are clean. We don't engrave ads into your molds.
No fake countdowns. No "only 3 spots left." And your commercial license never expires on work you've already made.
Nope — that's the whole point. Tell us you're making a candle, pick a shape, and the mold builds itself. Every setting has a plain-English explanation, and the defaults are already right for wax pouring.
A 3D printer (or a friend/library/print shop with one) and your wax or resin. Print the mold in PLA or PETG, then pour. For hot wax pours above 85°C, use PETG. The two-part mold snaps together, you pour through the built-in spout, and once it sets, it pops apart.
With the Pro, Lifetime, or Day Pass plans, yes — and unlike other tools, your commercial license for everything you made while subscribed stays valid even if you cancel. We think that's just fair.
No. All the 3D work happens right in your browser on your device. Your shapes and files are never sent anywhere — which also makes it fast.
Really. 10 clean downloads a day, forever. We'd rather win you over with the product than hold your files hostage.
Yes — use the "My text" shape option and type up to 12 characters. Perfect for custom name candle orders, wedding favors, and personalized gifts.
PLA molds handle paraffin wax (75–85°C) and soy wax (50–60°C) perfectly. For hotter pours above 85°C, print in PETG which withstands higher temperatures. Always do a test pour first.
