Latest Patents

Sugatani's latest patents include groundbreaking inventions such as an electron beam column for three-dimensional printing devices, a three-dimensional printing device, and a three-dimensional printing method. His innovations aim to provide a three-dimensional printing device that can irradiate approximately the same ranges on the surface of a powder layer simultaneously with multiple electron beams of varying shapes. The electron beam column features several electron sources, including those with anisotropically-shaped beam generating units, and beam shape deforming elements that modify the beam shapes of electron beams on the powder layer's surface. Additionally, a deflector in the electron beam column deflects the electron beam output from each source by a distance greater than the space between the beams before passing through the deflector.

Another notable invention is a three-dimensional laminating and shaping apparatus, which includes a column unit designed to output an electron beam and deflect it toward the powder layer's front surface. This apparatus also features an insulating portion that electrically isolates the three-dimensional structure from a ground potential member, an ammeter to measure the current flowing into the ground after passing through the structure, and a melting judging unit that detects when the powder layer is melted based on the current value measured by the ammeter.
