Abstract
A 5D printer, which additively manufactures an object, includes an extruder that can move linearly along three orthogonal axes and rotationally around at least one of the axes with respect to the object while depositing a material. A gantry is movable along X, Y and Z axes, and a trunnion table movable about A and B axes is mounted on the gantry. A platen is mounted on the trunnion table, and the extruder deposits the material on the platen while moving the gantry and trunnion table. A model of the object is analyzed to produce a stress tensor for the object, and the depositing is according to the stress tensor.
