Have you ever wondered whether human organs could be 3D printed? Wouldnt it save so many lives if we could customise the organs by printing them instead of waiting for the right donor? Let’s know about it more.
Hey lappie, print me an organ.….
Is that even possible? The short answer is yes. In the world where technological wonders are being invented which simply leave most of us in awe. Today we uncover 3D printing of human organs, how is it done? What is it made of? Is it sustainable? Let’s find out, come along!
What is 3D printing and how is it done?
- Just like the concept of conventional 3D printing, organ printing is based on similar principles.
- Wherein a computer model of the desired organ is fueled with the appropriate information needed for it to successfully run down layers of either plastic or wax until a satisfactory 3D object is acquired.
- A biocompatible form of plastic is used as the material for organ printing the organ, then the cells of the patient are planted into it. This allows the artificial organ to mimic the original organs of the human body.
- Then the 3D printed organ is intubated in the intubation chamber in order for the cells taken previously by the patient to grow.
- After an adequate amount of time, the organ is ready to be implanted into the patient’s body.
1. SWIFT: (Sacrificial Writing into Functional Tissue)
Sacrificial writing into function tissue (SWIFT) is a technique of organ printing implemented by planting real cells in an attempt to imitate authentic density that occurs in our human body.
2. Stereolithographic 3D Bioprinting
This method consists of creating a 2D pattern through spatially controlled light or laser which is layered by photopolymerization, later a 3D structure is built using the 2D pattern. The only drawback in this method is the scarcity of a specific biocompatible resin used to make these 3D models.
3. Drop-based Bioprinting (Inkjet)
Drop-based bioprinting produces cellular developments using droplets of a specific material, For instance, alginate polymerization is started by calcium ions in the substrate, which diffuses into the liquified bio-ink and permits the arrangement of a strong gel. However, this may make it less appropriate for more complicated organ structures.
4. Extrusion Bioprinting
Extrusion bioprinting consist of a specific printing fabric and cell line from an extruder, this makes it gentler to handle for fabric or cell statement, and permits for more noteworthy cell densities to be utilized within the development of 3D tissue or organ structures.
Medical science and technology are rapidly growing; however, a fully equipped 3D organ is yet to be made that can successfully be replicate human organs, however, scientists are working on this and soon we can expect this important invention that will potentially save many lives.
