Nature of Microelements Self Writing in Fiber Tips in UV-Curable Composites

Abstract

It is shown the possibility to obtain different microelements self-written in the fiber end: a large cylinder, cones, and spheres. The microelement shape depends on the light absorption in the mixture of monomers and the cone angle aperture of light going away from a fiber. The superposition of these two parameters results in the formation of a microelement of the specific type.
