Claim Text:
1. A method for verifying a deflection speed of an energy beam spot, said method comprising the steps of: generating, via an energy beam source, an energy beam spot; generating, via one or more computer processors associated with a control unit, a predetermined pattern on a work table with said energy beam spot while deflecting said energy beam spot with a first deflection speed; detecting, via said one or more computer processors associated with said control unit, first positions of said energy beam spot on said work table created with said first deflection speed; generating, via said one or more computer processors associated with said control unit, said predetermined pattern on a work table with said energy beam spot while deflecting said energy beam spot with a second deflection speed; detecting, via said one or more computer processors associated with said control unit, second positions of said energy beam spot on said work table created with said second deflection speed; and comparing, via said one or more computer processors associated with said control unit, said first and second positions, wherein:
