Abstract
A method of controlling an additive fabrication process includes providing a primary substrate and a test substrate. Polymer test material is extruded onto the test substrate utilizing an extrusion head. The extrusion head is moved relative to the test substrate, and a force required to move the extrusion head relative to the test substrate is measured to thereby generate test data. A part is fabricated by extruding polymer material onto the primary substrate utilizing the extrusion head. The test data is utilized to control at least one process parameter associated with extruding polymer material onto the primary substrate.
