Researchers from the University of Illinois, have created a new kind of 3D printer capable of producing complex shapes from sugar that can be used to grow biological tissues.

The printer uses a process called free-form printing to create intricate structures from isomalt—the type of sugar used to make throat lozenges—that could not be made with traditional layer-by-layer 3D printing.
