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 ...
A 3D structure can then be built in layers using the 2D pattern. Afterwards the bio-ink is removed from the final product. SLA bioprinting allows for the creation of complex shapes and internal structures. The feature resolution for this method is extremely high and the only disadvantage is the scarcity of resins that are biocompatible. [14]
Bioprinting drug delivery is a method for producing drug delivery vehicles. It uses 3D printing of biomaterials.Such vehicles are biocompatible, tissue-specific hydrogels or implantable devices. 3D bioprinting prints cells and biological molecules to form tissues, organs, or biological materials in a scaffold-free manner that mimics living human tissue.
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 ]
Volumetric bioprinting occurs when a bio-ink is placed in a liquid cell and is selectively irradiated by an energy source. This method will actively polymerize the irradiated material and that will comprise the final structure. Manufacturing biomaterials using volumetric bioprinting of bio-inks can greatly decrease the manufacturing time.
Organovo Holdings, Inc. is an early-stage medical laboratory and research company which designs and develops functional, three dimensional human tissue (also known as 3D bioprinting technology) for medical research and therapeutic applications.

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.
