About these chocolate molds

Chocolate should never sit on a bare 3D print: the layer lines hold residue that cannot be cleaned out. So every design here is a caster. You print it, pour a food-safe platinum silicone into it, and use the silicone as the mold. The print never touches food, and the chocolate peels out of the flexible silicone whole instead of being knocked out of a rigid tray.

For shiny bars and bonbons, temper the chocolate or use a compound coating that sets without tempering, fill the cavities, tap out the air, and chill for 15 to 20 minutes. Hot chocolate bombs are two half spheres: coat the cavity twice, fill one half with cocoa and marshmallows, and seal the halves with a warm plate.

Each download is a zip with the caster, a print and pour sheet and the silicone amount the tool measured. Every design was made with the free tray mold maker, so you can put your own shape or lettering into the same tray.

Questions

Chocolate molds: common questions

Are 3D printed chocolate molds food safe?

The print itself is not a food surface, so these designs never ask it to be one. You pour a food-grade platinum silicone into the printed caster and only that silicone touches the chocolate. Check that your silicone is sold as food safe.

Why does my chocolate come out dull or streaky?

Almost always untempered chocolate. Real chocolate needs tempering to set glossy and snap cleanly; compound or candy melts do not. A clean, dry silicone mold polished with a soft cloth helps the shine too.

How long does chocolate need in the mold?

About 15 to 20 minutes in the fridge for bars and bonbons, less for thin shells. Take it out as soon as it releases from the edges: left too long in the fridge it can bloom when it warms up.

Can I make a chocolate mold with my own logo or letters?

Yes. Upload a shape or type text into the free tray mold maker, switch it to the flexible silicone tray, and it builds a caster with as many cavities as fit your printer.
