So we were experimenting with printing chocolate. The first experiment (as photographed by Mark) showed that the prototype Lego chocolate pump works quite well, but that Green & Blacks diluted with water really isn't something that you want to eat.
Experiment 2 (not online) was more successful (hotter chocolate, in this case Marks & Spencer Swiss dark chocolate) but we found that it was producing really long strands [er, "logs" :-)] hanging down from the end of the print head, and so didn't produce nice blobs on the printout. We can produce lines of chocolate more effectively, so maybe we should be concentrating on chocolate plotters rather than chocolate printers, but "pen up" is clearly still a problem. So does anyone have any suggestions on good ways to cause the chocolate to drop off in smaller, cleaner blobs.
