Elegoo said they're going to send me some PLA+ instead of the extruder since I don't have an Elegoo and they can't guarantee that the extruder will work with my machine. Totally understandable. Can't wait to see what color PLA+ they send.They have what she is talking about in PETG too, it's not quite as shiny silky but it's rainbow color changing.
For the real shiny silky look PLA wins. For urchin hats and such it doesn't matter.
