In addition to 3D drug printing which aims at printing drug formulations, 3D printing can be used to fabricate materials functionalized by drugs, e.g., antibiotics or angiogenic agents. [8] This area which is a part of biomaterials engineering, aims at products such as adhesive patches for wound healing , hydrogel , and non-hydrogel implants ...
3D printing was invented by Charles Hull in the mid-1980s. [ 3 ] 3D printing is a process in additive manufacturing which uses a digital design to produce a physical copy. This process is carried out by a specific printer, which uses several layers in order to complete the design.
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 boy named Alex was also born with a missing arm from just above the elbow. The team was able to use 3D printing to upload an e-NABLE Myoelectric arm that runs off of servos and batteries that are actuated by the electromyography muscle. With the use of 3D printers, e-NABLE has so far distributed thousands of plastic hands to children.
3D printing is another major development in healthcare. It can be used to produce specialized splints, prostheses, parts for medical devices and inert implants. The end goal of 3D printing is being able to print out customized replaceable body parts. [30] In the following section, it will explain more about 3D printing in healthcare.
The field of organ printing stemmed from research in the area of stereolithography, the basis for the practice of 3D printing that was invented in 1984. [5] In this early era of 3D printing, it was not possible to create lasting objects because of the material used for the printing process was not durable.

This allowed the design process for customized, patient-specific hearing aid shells to become automated. The resulting designs could then be 3D printed to produce the customised hearing aids. This was the first high volume, end-use application of 3D printing, and today, 99% of the world's hearing aids are now produced using 3D printing. [6]
