Abstract: Traditional chocolate customization is high-cost and skill-demanding.Based on 3D scanning and 3D printing technologies,with the help of embedded system,we designed and implemented an integrated personalized 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 products,experiments shows that this platform enjoys better 3D printing precision,more friendly man-machine interface and provides better service of chocolate customization.
