I was at first really enthused by the Z18 but its various limitations really add up to me in the end :
- single material
- single extruder
- very high cost.
The Creatr XL seems cheaper to me and has a tad more possibilities :
- support material or bi color
- slightly bigger build
True enough, the Creatr doesn't seem to feature some welcome points like auto bed levelling or smart print head.

Both OEM still have the possibility to surprise us !
