Browsing 3Digital Cooks, I came across a post about Open Electronics’ method for modifying a RepRap 3D printer, specifically a 3Drag, to 3D print in chocolate. Sure, there are other printers out there that can 3D print in chocolate, even a few entirely devoted to the delicious practice, but Open Electronics modifies some of these methods for more reliable chocolate printing.
The process of converting your 3Drag printer into a chocolate printer is described in great detail at the Open Electronics site. What you’ll see going through OE author Boris Landoni’s project is that Boris has come up with a unique extruder design for maintaining the heat of the chocolate being used. As with many chocolate printing extruders, Boris’s design uses a simple syringe; however, as Boris points out (and friend Julian Sing has told me), tempering the chocolate is vital to the printing process.…
