bored of the same old ice cream bars and cones?a new machine that can produce amazing 3d-shaped ice creams for your kids in flat 15 minutesis here now. researchers from the massachusetts instituteof technology or mit have put together a 3d printer that can produce ice cream in anyshape. "first, we needed to print into a cooled environmentso that the ice cream would hold its shape
what is 3d printed food, once printed," kyle hounsell, an mit student,explained. along with kristine bunker and david kim,he built a cooling system using liquid nitrogen to fix the ice cream in place as it was squirtedout of the 3d printer's nozzle. the instant cooling allowed the printer tobuild up ice cream layers just as a traditional
3d printer squirts down layers of plastic. the students then had to balance the accuracyand printing resolution of the printer with the speed of printing, as a 30-minute waitfor ice cream is too long for some, the guardian
reported. "we imagine this technology being marketablein ice cream parlours where customers can order an ice cream treat, wait 15 minutes,and see the shape they chose be created," said another student.
