Title: David Walter Mason: Innovator in Printed Articles and Feedstock

Introduction

David Walter Mason is a notable inventor based in St. Helens, GB. He has made significant contributions to the field of materials science, particularly in the development of printed articles and feedstock for 3D printing. With a total of 2 patents to his name, Mason's work showcases innovative approaches to enhancing the properties of printed materials.

Latest Patents

Mason's latest patents include a printed article and a feedstock that incorporates a matrix forming material, specifically a polymeric material, along with a filler material dispersed within it. The filler material consists of glass flakes, which are characterized by an aspect ratio of average diameter divided by average thickness greater than or equal to three. This selection of aspect ratio is crucial as it controls the orientation of the glass flakes relative to the printed layer, leading to the formation of a depletion layer in the printed article. The technical effects of using angled glass flakes include improved adhesion between successive printed layers in 3D printing and a crack-stopping function. In a preferred embodiment, the glass flakes are coated with a conductive material, allowing the printed article to function as a moisture sensor. The depletion layer created enhances moisture permeability and results in a rapid change in electrical resistance due to moisture.
