Bioprinting (known as 3D bioprinting) is a combination of 3D printing and biomaterials, in order to replicate parts that mimic natural tissues, bones, and blood vessels in the body.
The main difference from traditional 3D printing concerns the processed material, composed of cells and biomaterials, based on carbohydrates, proteins and nucleic acids together with nanocomposites used to develop scaffolds, favoring cell adhesion and proliferation in engineered tissues and organ-like structures.
3D bioprinting is a production technique that creates complex 3D structures by selectively adding materials, as it allows you to control the size, shape, distribution and interconnectivity of the pores of the scaffold, a fundamental aspect when it comes to scaffolds and cell compounds. The process of fabricating 3D structures of biomimetic form starts from medical images, such as magnetic resonance imaging (MRI) and computed tomography (CT) using computer-aided design and manufacturing (CAD/CAM) technologies.
Although bioprinting is a relatively new technology, it has enormous potential to benefit areas such as regenerative medicine, personalized medicine, and drug and cosmetic discovery.
