Patent and Trademark Office for legal rights to a process for making a special kind of human cell.</span> <span data-start-time='13646' data-end-time='27354'>The company, Nano Dimension, says it uses a specialized 3-D printer to create an environment in which stem cells could grow into tissue.</span> <span data-start-time='27354' data-end-time='33271'>Stem cells can develop into many different kinds of cells in the body.</span> <span data-start-time='33271' data-end-time='38479'>They can also repair damaged tissues and organs.</span> <span data-start-time='38479' data-end-time='49896'>One kind, called induced pluripotent stem cells (IPS), are used to replace tissues lost to disease or injury.</span> <span data-start-time='49896' data-end-time='54979'>The term 3-D is short for three dimensional. </span> <span data-start-time='54979' data-end-time='61271'>That means an object has length, width and height.</span> <span data-start-time='61271' data-end-time='69375'>In 3-D printing, 3-D models are first created as files on a computer.</span> <span data-start-time='69375' data-end-time='77917'>The printer then uses a material like plastic or metal to create physical objects. </span> <span data-start-time='77917' data-end-time='86021'>The process involves making one layer at a time until the objects reach full form.</span> <span data-start-time='86021' data-end-time='89458'>Usually this process is slow.</span> </p></div><div class='control-buttons-sticky' style='display:none;'><div class='control-buttons'><button title='Back' class='back'
