This is a print of the foglight mount using 1.2mm nozzle. I have been finding a good print configuration for this nozzle. All previous products were printed with 0.4mm nozzle. Parts printed with larger nozzles are significantly stronger. The strength of 3D prints are mainly dominated by the wall thickness rather than the infill ratio. And large nozzles are capable of extruding material much faster. This cuts down the print time almost to 1/3. The major drawback of using large nozzles is the low resolution. But exterior parts are usually bigger and do not have fine features that need the high resolution capability. For exterior parts, I am going to print all future parts with the 1.2mm nozzle. After tuning the nozzle temperature (controls viscosity of the material), extrusion multiplier (controls the amount of material extruded), pressure advance ( compensate for the elasticity of the filament and the extruder), etc, I am happy with the result.
