Title: Masaaki Ogihara: Patents in Three-Dimensional Shaping

Introduction

Masaaki Ogihara is an inventor based in Matsumoto, Japan, and works at Seiko Epson Corporation. His patent work includes technologies for three-dimensional molding and the manufacture of shaped objects. He is associated with 5 patents.

Latest Patents

**Three-Dimensional Molding Device.** This invention describes a device that plasticizes material with a screw and ejects it through a nozzle. An adjustment mechanism controls the ejection rate by changing the opening of a flow path. The control section can vary the screw’s rotation speed in stages while ejection is stopped or as ejection resumes. During the resumption process, it decreases and then increases the screw’s rotation speed.

**Method of Manufacturing a Three-Dimensional Shaped Object, and Three-Dimensional Shaping System.** This invention determines the discharge part’s moving speed for each partial path based on the arrangement of path endpoints. The discharge part then moves at the determined speed while depositing shaping material onto a stage to build layers.

Career Highlights

Ogihara’s listed patents address both the control of material flow during three-dimensional molding and the coordination of movement and material discharge during object fabrication. These approaches focus on managing shaping processes through device control and path-based speed determination.
