Title: Daiki Hayashi: Innovator in Three-Dimensional Shaping Technology

Introduction

Daiki Hayashi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of additive manufacturing, particularly in three-dimensional shaping technologies. With a total of 3 patents to his name, Hayashi is recognized for his innovative approaches to shaping three-dimensional articles.

Latest Patents

Hayashi's latest patents include a three-dimensional shaping device and a three-dimensional shaping method. The three-dimensional shaping device is designed to shape a three-dimensional article by irradiating a powder material with an electron beam, effectively melting the powder material. This device features an electron beam emitting unit that not only melts the powder material to shape the article but also performs preliminary heating of the powder material by irradiating it with the electron beam before the actual shaping occurs. Notably, the electron beam emitting unit moves the irradiation position of the electron beam in a spiral pattern during the preliminary heating phase.

Another significant patent is the powder supply device, which includes a hopper that accommodates powder, a cylindrical roller that is rotatable around a rotational axis, and a wall surface that stores the powder in a space between the roller and the wall. This innovative device moves the powder stored between the roller and the wall surface in the direction of the roller's rotation and drops the powder as the roller rotates. The roller's peripheral surface features a plurality of groove portions extending in the axial direction, with at least one groove portion designed to change its capacity for accommodating powder in the axial direction.
