The Fabaroni 3D printer was designed by a group of MIT students in Neil Gershenfeld’s class, How To Make Almost Anything. The printer extrudes pasta dough and can make arbitrarily shaped pasta
We considered many different materials for extrusion: melted gummy bears, marzipan and chocolate just to name a few. Eventually we decided to go with pasta dough because we could easily adjust the fluidity of the dough as well and also because the ingredients are general and available to anyone.
A website was put up to display the process of making the 3D printer. Please take a look at it if you would like any further information about the design: http://fab.cba.mit.edu/classes/MIT/863.07/11.05/fabaroni/
My part of the project was controlling the motors and designing an interface to them.
