Abstract
According to at least one aspect, embodiments of the invention provide a 3D printer comprising an anisotropic head that solidifies, along anisotropic toolpaths, fiber swaths having an anisotropic characteristic oriented relative to a trajectory of the anisotropic tool paths, an isotropic head that solidifies, along isotropic toolpaths, a substantially isotropic material, a motorized drive for moving the anisotropic head and a build plate supporting a printed part in at least three degrees of freedom, and a controller configured to control the 3D printer to build the printed part by solidifying the isotropic material along the isotropic tool paths, solidifying the anisotropic material in fiber swaths tracking a non-concentric set of anisotropic tool paths for at least a first sequence of parallel shells, solidifying the anisotropic material in fiber swaths tracking an outer concentric set of anisotropic tool paths for at least a second sequence of parallel shells.
