3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
The first production system for 3D tissue printing was delivered in 2009, based on NovoGen bioprinting technology. [69] Several terms have been used to refer to this field of research: organ printing, bio-printing, body part printing, [70] and computer-aided tissue engineering, among others. [71]
The 3D-Printed Habitat Challenge tasked teams with printing 3D habitats for living on Mars. After competing and winning several awards, the lab used the funding to further develop the team’s ideas.
Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.

Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
