    Recent advances in consumer-grade 3D printers have enabled the fabrication of personal artifacts in aesthetically pleasing full color. However, the printed colors are usually different from the actual user desired colors due to the mismatching of droplets when the color reproduction workflow has been changed or the color profile setup is missing. In this paper, we present a preliminary experiment to investigate color reproduction errors in consumer-grade inkjet FDM 3D printers. Our results suggest that solving the problem requires initiating the workflow to minimize color reproduction errors such as using CMYK or sRGB color profiles. We also found that the mismatched color gamut between the input's desired texture and the 3D printed output depends on different file formats, and this finding requires future investigation.

    Preliminary Study on Surface Texture to Manipulate Perceived Softness of 3D Printed Objects
    (The Eurographics Association, 2019) Miyoshi, Motoki; Punpongsanon, Parinya; Iwai, Daisuke; Sato, Kosuke; Kakehi, Yasuaki and Hiyama, Atsushi
    Previous studies have attempted to manipulate the elastic properties of products from elements such as different materials and internal structures. In this paper, we investigate whether we can manipulate the softness perceived by the surface texture when using the FDM-3D printer. We investigated the perceived softness of the surface texture provided by Tymms et al., in which cones of 1 mm in height are arranged, by a subject experiment. From the experimental results, it was found that the hardness perceived by increasing the arrangement interval of the cones decreased and the subjects perceived softer the objects with the surface texture.
