This spiral lightbulb is always a challenge to print. It requires good retraction. As the print gets taller the spirals get pushed around by the print head. This makes the layer alignment difficult and as a result the surface finish suffers. That said this is the best one I have printed to date on any of my printers. The Behemoth is my 4th 3d printer.
I printed this one at 0.2mm layer height sliced with slic3r. Fill was 0.15 with solid infill threshold area set to 0. I also enabled cooling with min layer time of 15 seconds and min print speed of 10mm/s. I printed using silver 1.75mm PLA from Ultimachine at 198C. I used my floor fan on low to cool as it printed.
