22 Facts About Organ printing

Organ printing utilizes techniques similar to conventional 3D printing where a computer model is fed into a printer that lays down successive layers of plastics or wax until a 3D object is produced.

Ultimate goal of organ printing is to create organs that can fully integrate into the human body as if they had been there all along.

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.

Therefore, in the early days, 3D Organ printing was simply used a way to model potential end products that would eventually be made from different materials under more traditional techniques.

In 2004, the field of bioOrgan printing was drastically changed by yet another new bioprinter.

Organ printing using 3D printing can be conducted using a variety of techniques, each of which confers specific advantages that can be suited to particular types of organ production.

Sacrificial writing into function tissue is a method of organ printing where living cells are packed tightly to mimic the density that occurs in the human body.

SLA bioOrgan printing allows for the creation of complex shapes and internal structures.

Drop-based bioOrgan printing makes cellular developments utilizing droplets of an assigned material, which has oftentimes been combined with a cell line.

Extrusion bioOrgan printing includes the consistent statement of a specific Organ printing fabric and cell line from an extruder, a sort of portable print head.

Extrusion bioOrgan printing is frequently coupled with UV light, which photopolymerizes the printed fabric to create a more steady, coordinated construct.

One of the advantages of SLS printing is that it requires very little additional tooling, i e sanding, once the object is printed.

Recent advances in organ printing using SLS include 3D constructs of craniofacial implants as well as scaffolds for cardiac tissue engineering.

Materials for 3D Organ printing usually consist of alginate or fibrin polymers that have been integrated with cellular adhesion molecules, which support the physical attachment of cells.

Alginate hydrogel that is suitable for extrusion Organ printing is often less structurally and mechanically sound; however, this issue can be mediated by the incorporation of other biopolymers, such as nanocellulose, to provide greater stability.

Surgical usage of 3D Organ printing has evolved from Organ printing surgical instrumentation to the development of patient-specific technologies for total joint replacements, dental implants, and hearing aids.

Also, organ printing has been used as a transformative tool for in vitro testing.

Organ printing can assist in diminishing the imbalance between supply and demand by printing patient-specific organ replacements, all of which is unfeasible without regulation.

Altogether, organ printing possesses short- and long-term legal and ethical consequences that need to be considered before mainstream production can be feasible.

An additional impact of organ printing includes the ability to rapidly create tissue models, therefore increasing productivity.

One of the challenges of 3D printing organs is to recreate the vasculature required to keep the organs alive.

Challenges faced in the organ printing field extends beyond the research and development of techniques to solve the issues of multivascularization and difficult geometries.
