There are many difficulty in collecting data from a diffused reflection surface using an optical 3D scanning device. A spray-type developer and silicon molds are used for solving this problem. However, using developer can cause chemical reactions between objects and developer particles and uneven surfaces of the object. To overcome these problems, it is suggested an electrostatic powder coating method for even coating of particles onto surfaces for collecting 3D shape data. We have developed an automatic, electrostatic powder coating machine. The present study is aimed to explore powder materials suitable for electrostatic powder coating in terms of the easiness of coating work considering the characteristics of object surface. It was also conducted to verify materials that are smoothly coated well under various coating conditions and are advantageous in collecting 3D shape data.
