I watched the video and it’s really cool. I love the stuff he makes. It also makes me want a large format CNC as well.
You can do something similar with a laser cutter, but it will be more work. I made this window screen for my house on a laser-cutter with a 12"x24" bed. The final piece is about 9’ wide by 2’ tall. Not as big as his, but you could scale the process up as well.
I made it in 2 different layers. Where the cuts were to divide the layers into laserable sizes are in different places on each layer. So when you glue it all together, it creates one big piece.
Gluing it together was tricky but worked pretty well. I used spray paint instead of a brush, and that was much faster than what he showed in his video.

I agree that it would have been MUCH faster to do this on a CNC, but since I don’t have a CNC that could cut that size, I made do with what I had.
