Special Issue Information

Dear Colleagues,

Color 3D printing is a remarkable technology for customized manufacture and integrated production in different industries, despite a few key issues such as printing speed and size for industrialization. To date, there is only limited research on accurate color reproduction and on universal color reproduction method for different printing materials. This is mainly due to the lack of accurate color reproduction theory and evaluation system, for which the academic community has conducted several academic conferences to discuss the standardization of the color 3D printing process. It is time to start discussing high-fidelity appearance reproduction of 3D objects, particularly in faithful colors. To systematically understand colorization principles and color transmission in color 3D printing, an exhaustive literature review is needed to show the state of the art of color reproduction methods for color 3D printing.

Coloring, rendering, and acquisition issues are not comprehensively investigated and are challenging problems in developing a general color accuracy evaluation system. Furthermore, test benchmark design, experimental guidelines, and numerical analysis models for evaluating the color reproduction performance of color 3D printing are also key to implementing accurate material-aware color 3D printing. Furthermore, accurate color 3D printing processes can also be extended to full-color 4D printing with precise color response, which is also a new research area for scholars in the field of functional material design.

This Special Issue focuses on recent developments of color 3D printing, we encourage you submit a manuscript to this Special Issue focused on color 3D printing technologies, materials, and printouts designed for customized applications. Full papers, communications, and reviews are all welcome.

Color 3D printing has been widely used in many fields such as cultural, medical, industrial, and food. The color reproduction accuracy of 3D printed products in these fields is becoming increasingly demanding, which requires more reproduction methods and practical tools. At present, most color 3D printing devices use one quantitative index, that is, color difference, to directly predict the color reproduction quality. However, this single quantitative index is not optimal for the curved surface of 3D printed color objects. Based on color evaluation principles, in this study, five new quantitative metrics consisting of color gamut comparison index, color SSIM index, color FSIM index, iCID index, and subjective scaling values are proposed for comparison, and the corresponding GUI design and code implementation of new color quality evaluation system are performed by MATLAB. Moreover, the comprehensive color assessment of color 3D printed products is confirmed by utilizing standard image acquisition and microscopic imaging methods that are not limited to printing materials and sampling locations. The operation of this system is validated to provide interactivity, simplicity and high efficiency. As a result, the system can provide new valuable feedback for color separation and output calibration of color 3D printing devices. Full article

The objective of the present work is to evaluate the influence of material color on mechanical properties of fused deposition modeling (FDM) parts. The performance of the products is evaluated by testing eight different colors of acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) material in terms of tensile strength, compressive strength, and flexural strength. The analysis of data shows a significant difference in mechanical characteristics of prints depending on filament color. For different colors, these three strengths almost follow the same rising and falling tendency. In order to explore the relationship between mechanical strengths and filament colors, the color-mixing theory and the least-squares method are adopted to fit the best ratio coefficients of different color combinations. Results are presented showing that the strength value (e.g., tensile) of the mixed color can be evaluated through that of primary colors by fitting the other strength (e.g., compressive or flexural). It is shown that the predicted value is always no more than 7% error compared with the actual strength, in spite of two-color or three-color mixtures. An additional confirmation test with seven colored PLA filaments from different suppliers was conducted to focus on the extensibility. The outcomes show the maximum fitting errors of strengths for mixed colors in all cases are within 5%, proving the effectiveness and applicability of this predicted approach. This study can bring a detailed analysis that enables better estimation of the function of material color and contributes to improving the property of FDM printed products for consumers by choosing the suitable filament color.
