MABAR138 Medical researchers are making strides with bioprinting, in which they harvest human cells from biopsies or stem cells, multiply them in a petri dish, and use that to create a sort of biological ink that printers can spray. A Chinese construction company reportedly is building houses by using a giant 3-D printer to spray layers of cement and recycled construction waste to form walls and the rest of the structure. A company called Natural Machines recently unveiled a 3-D printing device called the Foodini, which can print ravioli pasta. Wired reported in 2013 that the three-wheel, two-passenger Urbee 2 vehicle, which is mostly made of plastic, was created at a 3-D facility.|{3|4|5|6|7|8|9|10|Three|Four|Five|Six|Seven|Eight|Nine|Ten} {Ways|Methods} Slot Bot Commands {Can make|Could make} You Invincible
