Title: **Seiichi Matsumoto: Innovator in Powder Evaluation for Lamination Shaping**
Introduction
Seiichi Matsumoto, a prominent inventor based in Kyoto, Japan, has made notable contributions to the field of material science, particularly in the evaluation of powders used in lamination shaping. With a total of two patents to his name, Matsumoto has focused on enhancing the precision and reliability of powder characterization, which is crucial for advanced manufacturing processes.
Latest Patents
Matsumoto's latest inventions include a method for evaluating lamination shaping powders that involve assessing their squeegeeing properties through established criteria. One significant aspect of his work is the evaluation of the satellite adhesion ratio and apparent density of the powder. If the satellite adhesion ratio is 50% or less and the apparent density is at least 3.5 g/cm³, it indicates that the powder can be uniformly spread during lamination shaping.
Additionally, Matsumoto has developed a method utilizing a shear test to determine the adhesive force of powders. This method employs a powder rheometer to acquire the relationship between normal stress and shearing stress, with a threshold adhesive force of 0.450 kPa or less ensuring the powder can spread uniformly.
