These instruments can be used to operate on tiny areas without causing unnecessary extra damage to the patient. Not only does 3D printing produce sterile tools, some are based on the ancient Japanese practice of origami, meaning they are precise and can be made very small. Sterile surgical instruments, such as forceps, hemostats, scalpel handles and clamps, can be produced using 3D printers. Using the 3D printed replica of his kidney, surgeons were able to assess the size and placement of the tumour and cyst. The transplant was fraught with complications as her father, who was her donor, had an incompatible blood group and his kidney was discovered to have a potentially cancerous cyst.

In January 2018, surgeons in Belfast successfully practiced for a kidney transplant for a 22-year-old woman using a 3D printed model of her donor’s kidney. In Dubai, where hospitals have a mandate to use 3D printing liberally, doctors successfully operated on a patient who had suffered a cerebral aneurysm in four veins, using a 3D printed model of her arteries to map out how to safely navigate the blood vessels. “3D printing has been used to create patient-specific organ replicas that surgeons can be use to practice on before performing complicated operations.” This type of procedure has been performed successfully in surgeries ranging from a full-face transplant to spinal procedures and is beginning to become routine practice. This technique has been proven to speed up procedures and minimise trauma for patients. Surgery preparation assisted by the use of 3D printed modelsĪnother application of 3D printing in the medical field is creating patient-specific organ replicas that surgeons can be use to practice on before performing complicated operations.

It has also been working on 3D printing skin grafts that can be applied directly to burn victims. The university announced in May 2018 that it’s organoids have a fully cell-based, functional blood brain barrier that mimics normal human anatomy.

The Wake Forest Institute in North Carolina, US, adopted a similar approach by developing a 3D brain organoid with potential applications in drug discovery and disease modelling. In May 2018, the company presented pre-clinical data for the functionality of its liver tissue in a programme for type 1 tyrosinemia, a condition that impedes the body’s ability to metabolise the amino acid tyrosine due to the deficiency of an enzyme. US-based medical laboratory and research company Organovo is experimenting with printing liver and intestinal tissue to help with the studying of organs in vitro, as well as with drug development for certain diseases.
