To a large extent, 3D printing technology is still in its infancy. If you thought it was all Etsy jewellery and plastic toys, though, think again. Joris Laarman has created a free-standing 3D ...

Now, researchers at North Carolina State University have developed a 3D printing technique that can create a variety of stable free-standing structures from liquid metal at room temperature. SUBSCRIBE ...

The constructs consist of three-dimensional (3D) free-standing skeletal muscle fibers co-cultured with motor neurons. We differentiated mouse neural stem cells (mNSCs) ...
