As it says in the title. This is a 3d print head for printing chocolate things.

This is in progress it is one of my quick change units or will be. Primarily i will use a Syringe (with insulated jacket) and use the plunger to push out the chocolate onto greaseproof paper attached to the bed using bulldog clips.

I started to design this, partly because i demonstrate printing occasionally and I struggle to find prints that are liked by a whole range of people from the young to the old, and male and female. The chocolate printer seams to get every one interested. For me the more people that can be inspired to participate in science or engineering the better

Notes,
Chocolate starts to melt at body temperature.
Printing from a syringe onto greaseproof paper clipped to the print bed means it is easy to clean.
the nozzle is large about 2mm and a print height of 2mm is reasonable prints can be completed in 10 to 15 mins depending on the size
white chocolate appears to give a better finish than milk or dark.
Bubbles can be a problem.
