The things in the video looked flat without overhangs. Any of them could be made by 3D printing with with either a resin printer or an FDM printer. To print large flat pieces on a resin printer, you will need to raise and tilt them, and add supports underneath to avoid suction problems. On an FDM printer, you can just print them flat on the print bed with no supports. Also, FDM printing is cheaper than resin printing.
