- A little bar of plexiglass, polyethylene, or similar
- A Roland Versa UV LEF-12 Printer (hi-quality chocolate) or a 3D printer (medium quality) or a Uniposca fine pencil (low quality)
- Food grade Silicone
Step 1: Printing Bass Relief
The VersaUV LEF-12 is Roland’s first flatbed UV-LED printer capable of printing on the surfaces of two- and three-dimensional objects up to 100mm thick.
I use Eco-UV S flexible UV curable inks, for print not with CMYK but with clear varnish ink. I can produce both a matte or high-gloss finish and also be built up for 3D textures and embossed effects such as Braille or my photoshop toolbar.
In alternative you can use 3D printers or an Uniposca to hand draw your graphic. I show you this solution in another instructables.
Step 2: Prepare the Box for the Mold
Step 3: Casting
Search in internet to found the productor near you. I use an italian company, Siliconi Padova.
Quickly cast the mixture in the box with the bar in the middle and the bass relief in the top.
Step 4: Mold Removal
Step 5: Chocolate
Just a little bit of vibrations before put it in the fridge.
