چاپگر سه بعدی 450 دلاری اصلاح شده مواد زنده را با بیش از 100 لایه می سازد

Modified $450 3D printer builds living materials with more than 100 layers

Living materials created with a 3D printer are like living tissues with one notable exception: You get to choose exactly which cells are in them, as well as their final 3D shape. Depending on the type of bacteria included in the print, the material can clean up contaminated water or break down waste materials such as plastic.
