Bio printing
Brief Summary
Bio Printing is fairly new adaptation of 3D printing technology. Simply put, it uses a specialized "bio-ink", that is composed of living cells to create living tissue structures. This bio-ink is contained in ink cartridges similar to those in a regular ink jet printer. When an object is created with one of these machines, bio-ink is laid down, one drop at a time on special "bio-paper". This paper is usually made of a collagen gelatin and supports and hydrates the delicate cells as they are layered. When the object is completed the bio-paper melts away or gets removed, and the new tissue structure is created.
Recap:
- Bio Paper layer is laid down
- Bio ink droplets are placed on the bio-paper one at a time until a layer is created
- The next layer builds on top of this one, and so on until the object is completed
- The bio-paper is either removed or dissolves naturally and (viola!) a new tissue structure is created
