#Watch A 3-D Printer Make A Pizza#This summer we heard about a 3-D printer for food developed with NASA funding but we didn't have much to look at in the way of a prototype. Now#lo and behold the printer has shown up at SXSW Eco and we caught a short demonstration from the makers a group from#Systems and Materials Research Corporation. The printer#served up a pie made with dough#ketchup and cream cheese(?.The printer is still in its earliest stages so the creators haven't quite perfected the process. Instead of making a classic slice they're showing off the proper levels of pizza viscosity with similar ingredients: ketchup for sauce cream cheese for a fine ricotta. The idea's more or less the same though: the printer lays down a layer of dough from a stock of simple non-perishable ingredients then layers the sauce (ketchup) and cheese (cream cheese) on top. A heated surface bakes the pizza.##You can see why NASA would be interested in the idea: send up a printer instead of boxes of food and you save space plus you give the astronauts a home-cooked meal. Also: it's fun to watch. Here you can see the printer laying down the cheese layer and one of the printer technicians being directed to add more pressure. Yum p
