dc.description.abstract3D printing has been extensively used for over two decades by various practitioners and professionals in the industry. This technique, which involves adding material from melted filament layer by layer based on CAD model geometry, imparts a unique appearance to the printed objects. The layering structure generates specific directional reflectance patterns on printed surfaces, leading to anisotropic highlights. Due to slight inaccuracies in the printing setup, the appearance of individual layers is not seamless and exhibits sparkle-like effects along the highlight. In this paper, we conducted a psychophysical experiment to analyze human perception of the printed objects, focusing on the intensity and width of the anisotropic highlights.We discovered that the contrast near the highlights and the variability of pixel intensities along the highlights are highly correlated with human ratings. Lastly, we present a straightforward method utilizing these computational features to enhance the visualization of 3D printed objects.en_US
