Abstract Scope |
Reactive extrusion is a new AM process that enables extrusion-based layer-by-layer deposition of thermoset polymers from liquid precursors that are mixed on demand at the point of application and cure at ambient conditions. Because the materials cure in situ, significant crosslinking can occur between material layers, resulting in parts with very little anisotropy. Moreover, the use of liquid thermoset precursors that cure in situ avoids the need for energy expenditures associated with heating the deposited material. This presentation describes a reactive extrusion AM testbed and the mechanical properties of parts fabricated with the testbed. When coupled with a large nozzle and high material flow rates, the reactive extrusion AM testbed described in this presentation is capable of creating strong, nearly isotropic parts in a fraction of the time it takes other conventional additive systems, while using appreciably less energy. |
