Our Smart Chinese clients printed a HUGE mural with 10m*12m on the wall using the stitching function in the wall printer software.
The standard printing height of the wall printer is 2 meters high, but we developed the STITCHING FUNCTION in the software. If you need to print a large mural on the wall, you just need to lift your printer by scaffold and print the picture part by part.
