The methods introduced in this paper allow direct slicing and manufacture of freeform functionally graded material (FGM) objects using additive manufacturing (AM). The FGM objects received as input are specified as complexes of trimmed parametric trivariate volumetric cells, and contain the design for both the geometry and (heterogeneous) material composition of the model. We present efficient methods that enable the fabrication of general volumetric freeform designs, following the modeling…

Data-Driven Material Modeling with Functional Advection for 3D Printing of Materially Heterogeneous Objects

A bitmap-slicing framework designed to inform material property distribution in concert with slice generation is demonstrated and the ability to integrate multiple geometry-based data sources to achieve high levels of control for applications in a wide variety of design scenarios is emphasized.
