Fabrication of Edible lenticular lens

Abstract

Lenticular lenses exhibit the color changing effect depending on the viewing angle and the vanishing effect in certain directions. In this study, we propose two fabrication methods for edible lenticular lenses. One is the mold forming method, and another is the knife cutting method using a knife with the inverse structure of a lenticular lens created by an SLA 3D printer. We also evaluate the properties of the end products. The IOR of material is optimized by using ray tracing simulation.
