3. Experiment Method
A measurement method of sample of powder form is an x-ray diffractometor(Fig. 9).

3.1. Making of Sample Powder
A Sample is made a powder form. A diameter of powder has good reproducibility as smaller. But generally 10~35μm is a suitable size of sample. We must caution a deterioration by air, gas, humidity and pouri

The materials that have various colors is made and commercialized and the one that is possible for electroplating on it is commercialized too. After the technology for 3D printing is evolved, the price of the materials for 3D printing ink may go down and it causes more and more supply of 3D printer for individual per
uses a laser as the power source to sinter powdered material (typically metal).
The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part.
After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed.
