11 Facts About 3D bioprinting

Generally, 3D bioprinting can utilize a layer-by-layer method to deposit materials known as bio-inks to create tissue-like structures that are later used in various medical and tissue engineering fields.

Currently, 3D bioprinting can be used to print tissue and organ models to help research drugs and potential treatments.

Pre-3D bioprinting is the process of creating a model that the printer will later create and choosing the materials that will be used.

Common technologies used for 3D bioprinting are computed tomography and magnetic resonance imaging .

Artificial organs such as livers and kidneys made by 3D bioprinting have been shown to lack crucial elements that affect the body such as working blood vessels, tubules for collecting urine, and the growth of billions of cells required for these organs.

Post-3D bioprinting process is necessary to create a stable structure from the biological material.

The application of biomimicry in 3D bioprinting involves creating both identical cellular and extracellular parts of organs.

Third approach of 3D bioprinting is a combination of both the biomimicry and self-assembly approaches, which is called mini tissues.

Indirect extrusion techniques for 3D bioprinting rather require the printing of a base material of cell-laden hydrogels, but unlike direct extrusion contains a sacrificial hydrogel that can be trivially removed post-printing through thermal or chemical extraction.

Piezoelectric 3D bioprinting has short duration current rather applied to a piezoelectric actuator, which induces mechanical a vibration capable of ejecting a small globule of bioink through the nozzle.

Laser-based 3D bioprinting can be distinguished between two major classes in general, those being based upon either cell transfer technologies or photo-polymerization.
