Abstract

The claimed subject matter includes a system and method to design 3D objects for fabrication. In embodiments, the method includes sampling coordinates of a two-dimensional object. The method also includes generating fabrication coordinates based on the coordinates and a plane comprising a top layer of a three-dimensional (3D) object. Additionally, the method includes generating a 2D triangular mesh for the top layer of an overhang based on the sampled coordinates, an angle between the top layer and two points in a previous top layer border less than or equal to an overhang threshold angle.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for designing three-dimensional (3D) objects for fabrication, the method comprising:
 sampling coordinates of a two-dimensional object;   generating fabrication coordinates based on the coordinates and a plane comprising a top layer of a three-dimensional (3D) object; and   generating a 2D triangular mesh for the top layer of an overhang based on:
 the sampled coordinates, and an angle between the top layer and two points in a previous top layer border being less than or equal to an overhang threshold angle.
