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 ...
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 work at Cornell was expanded using specialized bioprinters produced by Seraph Robotics, Inc., a university spin-out, which helped to catalyze a global interest in biomedical 3D printing research. 3D printing has been considered as a method of implanting stem cells capable of generating new tissues and organs in living humans.

The most common application of 3D printing in pharmaceuticals is the production of tablets and capsules. 3D printing offers precise dosing, the ability to design tablets with improved release profiles, and the capability to combine multiple medications into a single tablet. [3]
Surgical usage of 3D printing has evolved from printing surgical instrumentation to the development of patient-specific technologies for total joint replacements, dental implants, and hearing aids. [27] In the field of organ printing, applications can be applied for patients and surgeons.
Like the thermoplastics that are often utilized in traditional 3D printing, bio-inks can be extruded through printing nozzles or needles into filaments that can maintain its shape fidelity after deposition. However, bio-ink are sensitive to the normal 3D printing processing conditions. Differences from traditional 3D printing materials
