Flexible Filament
The modified extruder assembly and 3mm filament makes it easier to feed flexible filament (like NinjaFlex) successfully
Fast prints
The volcano hotend and 0.8mm nozzle allows for high speed printing
Lack of enclosure makes this poorly suited for filaments prone to warping (ABS, non-filled Nylon)
Using filaments filled with fiberglass or carbon fiber can prevent warping, although these need abrasion-resistant nozzles)
Large nozzles ooze a lot, making it hard to use materials such as PETG without lots of stringing.
