Embodiment Construction

[0019] For a general understanding of the present embodiment, reference is made to the accompanying drawings. In the drawings, the same reference numerals are used to refer to the same elements throughout.

[0020] figure 1A side cross-sectional view of an exemplary embodiment of a three-dimensional object 100 according to the present disclosure is shown. The object 100 includes a first material region 104 , a second material region 106 , a third material region 108 , a fourth material region 110 , and a fifth material region 112 . Material regions 104 - 112 are collectively referred to as plurality of material regions 102 . The fifth material region encapsulates the remainder of the material region 102 assembled into various arrangements 116 , 122 and 124 . Each arrangement 116, 122 and 124 includes at least two different regions of material having different colors, as explained in more detail below. Arrangements 116, 122 and 124 are spaced apart from one another by port...

Abstract

A three-dimensionally printed object includes a plurality of different material regions that together define a surface region of the object. The plurality of different material regions include a first material region and a second material region. The first material region has a first color, and the second material region has a second color that is different from the first color. The different material regions overlap from each other within the object by different amounts viewed from different directions so that different proportions of light from the plurality of different material regions are visible to an observer viewing the surface region of the three-dimensionally printed object from different view directions, different view angles, and with illumination lighting the surface region at different angles. A coloration of the surface region is altered based on the proportions of light from the plurality of different material regions visible to the observer.

Description

technical field [0001] The present disclosure relates generally to three-dimensional object printing, and in particular to printing three-dimensional objects with colors that vary based on viewing and lighting angles and directions. Background technique [0002] Various techniques have been used to form objects with iridescent surfaces, ie surfaces that appear to change color as the angle at which the surface is viewed or the angle of illumination changes. In one example, a diffraction grating disposed on the surface is used to reflect or transmit different portions of incident light. The different light fractions are seen as the field of view of the image that changes with the angle of incidence. In another example, multiple images are divided into interlaced strips on the surface and covered with a lenticular lens. The lenses are aligned with the interleaved images such that light from each individual image is emitted in the same corresponding direction. The structure s...
