[0042] Working principle: when the metal tool needs to be quickly formed, the metal tool drawing that needs to be quickly formed is input into the control panel 23, and then a large amount of metal powder is scattered on the surface of the powder laying table 20. Before work, whether the base 17 and the working room 1 are horizontal is the key to whether the metal tool is formed after printing.

[0044] After printing, the scraping motor 12 drives the cleaning scraping strip 10 to rotate outward, the control motor 15 drives the electric telescopic rod 14 to push the cleaning scraping strip 10 out, and the scraping motor 12 drives the cleaning scraping strip 10 to repeatedly scrape the galvanometer 16 on the surface of the galvanometer 16, so that the galvanometer 16 can be quickly put into use next time, and the work efficiency is greatly improved.
