Three-dimensional printing of a porous matrix on a container

Abstract

This disclosure describes container(s) having an ultraviolet (UV)-cured matrix and methods to create the same. The glass container according to this disclosure has a bottom and a body extending in a direction away from the bottom along a longitudinal axis. The body has a surface having an UV-cured matrix including UV-curable varnish drops arranged in a plurality of layers and having voids existing therebetween to form a porous matrix structure. A method of printing a UV-cured matrix on a glass container is also disclosed that includes identifying a plurality of locations on a body of the container where the UV-cured matrix will be formed, determining a height value of the UV-cured matrix at each location, applying at least one varnish layer to the body according to an assigned grayscale or numeric value at each location, and applying UV light to cure each respective varnish layer.
