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.
I have the Behemoth printing! I printed out the slic3r version of the tornado posted by Sound on thingiverse. I thought this would be a good test for the printer. This isn’t your typical first print. No calibration cubes here. Just right to business. It turned out very well. Layer alignment was excellent. I was a little worried that I might have issues with large objects This is the biggest object I have ever printed. I’m relieved now and can spend time cleaning up the wiring and install the end stops for x and y.
– 210mm tall
– 0.31mm layer height
– 195 C
– Active cooling from a floor fan on low
– 2 perimeters
– 3 solid layers on bottom, 0 layers on top
– 0% infill density
– build envelope (350mm+ on X, 350mm+ on Y, and 400mm+ on Z)
– 0.35mm steep head nozzle with makergear hot end.
I got a really good deal on this in an ebay auction. It is a reprap LCD controller for ramps 1.4. This will let you print without a computer. I’m using this with the latest version of Marlin firmware which has built in support.
I’ll post a follow up video once I get it hooked up.
