- It’s completely standalone, and receives input models via a simple SD card. We’re not sure if this is good or bad, but it is certainly simple. With this feature it *definitely* is a desktop printer, since you’ll have to grab it to insert the SD card when you want to print.
- Upgradeable from a one-head machine to a two- or three-head machine. This feature likely would permit different materials and/or speedier printing, but according to the specs you lose a bit of X-axis build chamber as you add heads.
