Abstract
The system described assumes that the physical properties of the bind sites will be sufficiently repeatable to be tabulated based on a limited set of control constraints: filament material, temperature of the print head, feed rate, temperature of the substrate, and filament orientations at the bind site, etc. The main idea of this system is to utilize the bind sites and the connection and directionality of the threads as a lattice that can then be fed into a finite element analysis (FEA) algorithm for simulation in order to extract the macro physical properties of the part being produced. These repeatable bind site tabulated values can then be used to provide the cell properties for the FEA. The micro properties of the bind site can also be encoded into explicit equations, neural networks or other approximators.
