Title: David E Snead: Innovator in 3D Slicing Technology

Introduction

David E Snead is a notable inventor based in Canyon Country, CA (US). He has made significant contributions to the field of 3D printing and stereolithography. With a total of 4 patents to his name, Snead has developed innovative methods that enhance the capabilities of 3D object representation.

Latest Patents

One of Snead's latest patents is the "Boolean layer comparison slice." This invention describes a method and apparatus for slicing a three-dimensional object representation into multiple layer representations. These layer representations are subsequently used to form the object layer-by-layer according to the principles of stereolithography. If not already provided in the object representation, a plurality of layer boundary representations are first formed. The boolean difference of successive layer boundary representations is then computed to derive boundaries of up and down-facing regions. This enables different cure parameters to be specified for these different regions, enhancing the precision and quality of 3D printed objects.
