Nope sorry. Without an enclosure, there is no way it is going to print the height that it claims without serious warping issues or headaches. It looks gigantic and impressive but if you actually look at the printer in the picture, the big build is only around 22cm (look at the stepper motor, its around 4.2cm high, if you multiply the height in the photo by steppers, you can average around 20cm that the nozzle is currently at) and has not finished yet, so I'd be keen to see their 24" cubic build, like an entire helmet or something printed in one go.

Also the build platform... Glass plate? no heating element? How on earth would they make a 24" high model without a heated bed and no enclosure? if it can this certainly is a magic machine!
