Introduction to Bioprinting

Foundations and Technology Overview

Bioprinting, a convergence of additive manufacturing and living cell technology, underpins the evolution of personalized regenerative therapies. This technology uses specialized bioinks—mixtures of living cells, natural hydrogels (like alginate, gelatin, and collagen), and synthetic polymers—in a layer-by-layer deposition process to recreate tissue-like architectures. In recent decades, scientists transitioned from manual tissue engineering to computer-controlled deposition thanks to the pioneering work done in the 1980s and 1990s. For example, Charles Hull’s invention of the first 3D printer in 1984 directly influenced subsequent work when Robert J. Klebe used an inkjet printer to deposit living cells in 1988. These initial efforts laid the scientific groundwork for the sophisticated systems available today.

Modern bioprinting employs various methods such as extrusion-based printing, inkjet deposition, laser-assisted techniques, and stereolithography. Each method carries unique benefits; a notable example is the nozzle-free laser-assisted technique that achieves near single-cell resolution.
