3d Printing Is The Printing Of Tissues Themselves

One of the most complex processes that is being investigated in 3D printing is the printing of tissues themselves. It is the same process as printing all other objects, with the only difference being in the extremely complex materials and structures that need to be printed. The only tissue that can currently be printed is cartilage, being of the "simplicity" of the tissue; it is only a single stratified cell that is easily adapted and not nearly as complex as printing organs. The dumbed down version of how the tissue is printed is by creating a type of frame of biocompatible materials such as gelatin and thermoplastics, and adding a bio ink made of cartilage cells to the frame, which theoretically creates a cartilage that's both strong and soft to most resemble real cartilage. The initial problem of creating an ink that is liquid at room temperature (to print) and solid while at body temperature was solved by a few groups of scientists. The perfect combination was a mixture of N–isopropyl acrylamide and hyaluron which is liquid at room temperature and solidifies when printed onto a surface heated to body temperature.

An entire different scope of what 3D printers are capable of is in the culinary arts. There have been quite a few 3D printers that are capable of printing out edible foods. Chocolate is one of the simplest things
