As Jason named chocolate as the Drama Queen of 3d food printing, we are always happy to meet new people working on it. Our new digital cook friends from Ukraine just send us some cool videos printing chocolate!! If you want to learn more about them make sure to check their website.
Their printer, in my opinion, looks like a sturdy custom frame with a nice color interface, and tweaked 3dDrag extruder perhaps.
You can watch more video on their youtube channel here.
