A team of researchers at M.I.T. has developed a new 3D-printing technique, called Living Additive Manufacturing, which allows one to morph the color, shape and size of an object once printed. The process involves the use of ultraviolet light to alter the chemical structure of a 3D-printed object, which eventually morphs the stiffness of the material, halts or restarts its growth.

Senior author Jeremiah Johnson, Associate Professor of Chemistry at M.I.T. says the process simply prints a material, uses light on it, transforms it into something else or grows it further, writes Tech Crunch.

Lead authors Mao Chen and Yuwei Guhey, who refer to the original material as “parent” and the adapted object as “daughter,” say the technique opens up the possibility to create daughter gels that are softer, stiffer, thermally more responsive, more healable and more weldable than their parent material, reports 3D Printing Industry
