Exploitation of 3-D printing technique in design and prototype of an eyeglass frame for Philippine Eye Research Institute

Rapid prototyping techniques, including three-dimensional printing, have unlocked new possibilities to manufacture any given three-dimensional object into a model or prototype, directly from a CAD file through the additive deposition of individual cross-sectional layers of the part. Through the years, additive manufacturing has evolved from producing prototypes for form, fit and functional testing to producing final end-products for consumer use. The 3-D printing has made its mark for providing cost effective product along with making complex geometries possible. This paper gives an overview of a 3-D printing process and presents a case study for an innovative eyeglass frame design for the Philippine Eye Research Institute that addresses the problems with slipping of the nose pads of eyeglasses and irritation for wearing eyeglasses for a long period of time.
