Three dimensional (3D) printing is a revolutionizing technology, which endows engineers,
designers, and manufacturers with the ability to rapidly translate digital sketches into
physical objects. The advantages that lie in the high resolution and accuracy of this
technique were not concealed from the eyes of tissue engineers that soon harnessed this
power for fabrication of complex biological structures. Nevertheless, while the conventional
3D printing scheme is oriented to yield durable and sturdy structures, the delicate nature of …
