Based on 3D scanning and 3D printing technologies, with the help of embedded system, we designed and implemented an integrated personal- ized chocolate 3D printing system. Utilizing the depth camera of Microsoft Kinect and related driving circuit, our platform enhanced the stability of 3D scanning by controlling the translation and rotation of a Kinect. In order to accommodate the 3D printer to chocolate and thus to acquire better precision and effect, we redesigned the 3D printing head, and improved many modules such as temperature controlling and hot bed. The scanned geometry was optimized, which greatly improved the efficiency of the system. Comparing with similar commercial prod- ucts, experiments shows that this platform enjoys better 3D printing precision, more friendly man-machine inter- face and provides better service of chocolate customization. Key words: 3D scanning; geometry optimization; 3D printing; personalized chocolate fabricatio
