Abstract

In fused filament fabrication (FFF), a material extrusion additive manufacturing (AM) method, thermoplastic filament is extruded though a rastering nozzle on prior layers building a 3 dimensional object. The resulting strength of the FFF produced part is limited by the strength of the weld between each layer. While numerous factors can affect the weld strength, the temperatures of the extrudate and the previous layer dictate the amount of interdiffusion and thus the weld strength. To investigate the relationship between the FFF processing conditions, extruder temperature and feed rate, and final build strength, infrared cooling profiles and weld fracture strengths are compared.
