Title: Walter Hsiao: Innovator in Additive Manufacturing

Introduction

Walter Hsiao is a prominent inventor based in San Mateo, California. He has made significant contributions to the field of additive manufacturing, holding a total of 10 patents. His work focuses on improving the efficiency and accuracy of 3D printing technologies.

Latest Patents

One of Hsiao's latest patents is a method for improved infilling of part interiors in objects formed by additive manufacturing systems. This innovation involves a slicer in a 3D object printer that identifies positions and local densities for infill lines within a layer of an object. The local density of each infill line is filtered, and a control law is applied to identify errors in local density compared to a target density. This iterative process continues until the error is within a predetermined tolerance range, generating machine-ready instructions for the printer to achieve the desired infill density.

Another notable patent is a system and method for determining the spatial distribution of variable deposition size in additive manufacturing. In this process, a 3D object model is divided into slices targeted for an additive manufacturing process that deposits material at variable sizes. A thinning algorithm is applied to the contours of each slice, forming a meso-skeleton. The topological features are reduced over several passes, allowing for the determination of a slice-specific printable feature size. The adjusted slices are then assembled into an object model for manufacturing.
