Advanced Surface Color Quality Assessment in Paper-Based Full-Color 3D Printing

Abstract: Color 3D printing allows for 3D-printed parts to represent 3D objects more realistically, but its surface color quality evaluation lacks comprehensive objective verification considering printing materials. In this study, a unique test model was designed and printed using eco-friendly and vivid paper-based full-color 3D printing as an example. By measuring the chromaticity, roughness, glossiness, and whiteness properties of 3D-printed surfaces and by acquiring images of their main viewing surfaces, this work sk… Show more

“…Tian et al skillfully explored the quantitative correlation between the color feature of a paper-based 3D-printed coloring layer and its blank layer attached underneath using ∆E* ab , the feature similarity index measure of color images (FSIMc), and an improved color image difference (iCID). This study ignored the problem of 3D sample boundary coloring [20]. Therefore, imagebased metrics have mature applications in the evaluation of the color-reproduction quality of color in 3D printing as efficient numerical visualization tools.…”

“…Color 3D printing is gaining increasing popularity in recent years, as it enables customized production in various industrial applications based on different substrates, including plastic [3][4][5][6][7], powder [8,9], paper [10][11][12][13][14], metal [15,16], glass [17], food [18], and organism [19]. While the seven categories of applications for color 3D printing techniques range from processes to coloring materials in 3D printing, they follow the same subtractive color theory standardized by the CIE (Commission Internationale de L'Eclairage) and the ICC (International Color Consortium) for 2D printing.…”

“…The high thermal expansion of pure polymers creates a loose bond between the layers during printing, leading to the formation of the staircase (Figure 1). As an inherent issue, the formation of staircases has a significant negative influence on the surface appearance of FDM parts [9][10][11][12][13].…”

“…Particularly, color reproduction is a significant aspect of 3D printing since a colored appearance of the printed objects would be most favorable for real-world applications such as ornaments, graphic labeling, information coding, etc. ( 14 17 ). However, the current feedstocks are mostly colored by doping with dyes or pigments, whose long-term color fidelity and stability remain an open question.…”
