3D printing in nature

3D printing in nature, also known as biological or biomimetic 3D printing, refers to the process where living organisms create complex structures, such as bones, shells, and tissues, through natural growth processes that mimic additive manufacturing. These processes involve cells building layers of materials like calcium carbonate or proteins over time, forming intricate, functional structures. Scientists study these natural techniques to improve artificial 3D printing, aiming to develop synthetic materials and methods that replicate the efficiency, precision, and adaptability of natural formation, advancing fields like tissue engineering, regenerative medicine, and sustainable manufacturing.
