This is neat, but the technology itself isn't "new": the basic idea has been around for decades, and I've seen videos from companies demonstrating this at trade shows for a while as well. This is also how Firefly Aerospace 3d-prints their rockets.

Seems like a more costly and complicated version of Wire Arc Additive Manufacturing (WAAM). What's the benefit of using lasers vs. simple electrical current?

Precision, I think. Much easier to confine the heat to the material you want with a laser.
