In addition to output by 3D printer, post-processing such as polishing and coloring was time-consuming. Also, the hue were not very good and sometimes the finished product was not as desired.

The size of the output at a time was increased, greatly reducing labor and time. Output could be done at a level that did not require post-processing such as scraping off and polishing. In addition, coloring work is no longer necessary and colors can be expressed as they are in the 3D data, expanding the range of applications and making it possible to realize a variety of offers.
