Abstract Scope |
A dual nozzle polymer material extrusion additive manufacturing (MEXAM) system that utilizes both a large diameter nozzle for rapid shape fill and a small diameter nozzle for fine detailed shaped accuracy is investigated. The system is used to produce fully filled samples with complex geometry, taking advantage of its novel slicing and manufacturing system. When manufacturing with the dual diameter setup, large fill areas take advantage of the time efficiency of the large diameter nozzle and small, finely detailed areas can be accomplished through the small diameter nozzle. Three combinations of nozzle diameters are used to produce multiple complex geometry samples for density, shape accuracy, and dogbone specimens for tensile testing of the small/large infill interface. Density measurements demonstrate smaller nozzle diameter affects part shape accuracy, and the tensile experiments demonstrate mechanical property effects of the nozzle diameter on interface geometry. |
