This printer is highly experimental right now. It never worked very well with the original Leapfrog configuration. It has been modified to use more readily available off-the-shelf parts, but good printing profiles have not been figured out for this printer.
Dual Extrusion allows for multi-material prints, including possibly dissolvable support material
Heated enclosure may make it work better with filaments prone to warping
Web-enabled, allowing for direct printing over the network
Triple-Z screws allow for mechanical leveling of the build plate
Granite build plate
Not very flat, although this can be componensated for through software bed leveling
Difficult to remove prints
Very slow to heat and cool (about 30 minutes to pre-heat)
The mechanical leveling's benefit is reduced, since the surface isn't flat to begin with
Feeding issues
Filament path is not constrained enough to use flexible filaments
Custom "e3d" adapters to allow use of generic nozzles sometimes allows filment to jam instead of feed properly
Heated chamber isn't actually temperature controlled
It just heats whenever the bed is heating. It keeps it warmer than an unheated chamber, but you can't actually set a desired temperature
