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.

Yep, iv seen them printing that rocket and talking about how they had to add extra processing steps to account for thermal warping initially.
