What is Light based bioprinting

Adapted from stereolithography (SLA) processes, light-based bioprinting produces constructs by initiating chemical reactions that solidify or cure bioinks only where they have been illuminated. The two types of light-based technologies, digital light processing (DLP) and holographic, are much faster because they cure whole layers even blocks of bioinks simultaneously. Thanks to small points of light in the millions, light-based bioprinters are also able to recreate more intricate details at much higher resolutions.
