Photoinitiation is the process where light energy is absorbed by a photoinitiator, leading to the generation of reactive species that initiate polymerization reactions. This mechanism is crucial in applications like 3D printing and UV-curable coatings, where precise control over polymerization is required.

Photoinitiation

Light Energy

Photoinitiators are compounds that produce reactive species when exposed to light, initiating polymerization in processes like 3D printing and UV-curing of coatings and adhesives. They play a critical role in the efficiency, speed, and control of light-driven polymerization, affecting the final properties of the material.

Reactive species are highly reactive molecules that can cause significant damage to cells and tissues, but also play essential roles in cell signaling and homeostasis. They include free radicals and non-radicals, and their balance is crucial for maintaining health and preventing diseases such as cancer and neurodegeneration.

3D printing, also known as additive manufacturing, is a transformative process that creates three-dimensional objects from digital files by layering materials. This technology enables rapid prototyping, customization, and complex geometries that are challenging to achieve with traditional manufacturing methods.
