Bio and biocompatible 3D printing

“

- [Presenter] Bio and biocompatible additive manufacturing techniques are changing the field of medicine. Bioprinting is a branch of medicine currently under development that combines 3D printing with biomaterials, such as cells and growth factor to create tissue-like structures. Just like plastic 3D parts are built up layer by layer, so are the scaffolds and cellular structures in bioprinting. The printer uses bioink, which is made up of biopolymers such as collagen, gelatin, hyaluronan, silk, alginate, and nanocellulose. Techniques vary. Extrusion bioprinting uses a syringe-like printhead to create a gel-like scaffold which is then seeded with cells. Once the scaffolds are printed, they are processed. During post-processing, the print may be warmed, exposed to UV light, or go through another physical or chemical process. And once it's done, the cells will start multiplying and acting like real tissue. But…
