Resin print area size is determined by the size of the LCD screen available in the unit. The L model used a 345.6mm X 194.4mm LCD screen. The new model Phenom XXL will have a 527mm x 296mm LCD screen.
The L model ran for $3000 and the new printer will be larger and possible much more expensive. But as of this article, no price has been revealed. Those in the medical and the entertainment industry might be among the most interested to buy this printer.
