Method for additively manufacturing of objects based on tensile strength

A method for additively manufacturing an object, comprising the steps of determining a stress tensor for the object and depositing a material with an extruder (304) according to the stress tensor. The extruder can move linearly along three orthogonal axes and rotationally around at least one of the...

Beschreibung
Zusammenfassung:	A method for additively manufacturing an object, comprising the steps of determining a stress tensor for the object and depositing a material with an extruder (304) according to the stress tensor. The extruder 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 (320) 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 (305) is mounted on the trunnion table, and the extruder deposits the material on the platen while moving the gantry and trunnion table
