Stencil‐based 3D facial relief creation from RGBD images for 3D printing

Abstract

Three‐dimensional (3D) selfie services, one of the major 3D printing services, print 3D models of an individual's face via scanning. However, most of these services require expensive full‐color supporting 3D printers. The high cost of such printers poses a challenge in launching a variety of 3D printing application services. This paper presents a stencil‐based 3D facial relief creation method employing a low‐cost RGBD sensor and a 3D printer. Stencil‐based 3D facial relief is an artwork in which some parts are holes, similar to that in a stencil, and other parts stand out, as in a relief. The proposed method creates a new type of relief by combining the existing stencil techniques and relief techniques. As a result, the 3D printed product resembles a two‐colored object rather than a one‐colored object even when a monochrome 3D printer is used. Unlike existing personalization‐based 3D printing services, the proposed method enables the printing and delivery of products to customers in a short period of time. Experimental results reveal that, compared to existing 3D selfie products printed by monochrome 3D printers, our products have a higher degree of similarity and are more profitable.

“…Dynamic stencil lithography involves motion of the stencil relative to the substrate during the deposition or in between the deposition steps and allows micro-/nanopatterns, multilayers, and different materials for in situ fabrication. Static stencil, as indicated by its name, involves a static substrate and stencil [ 89 , 90 , 93 ].…”
