Yeah they really buried the lede here. The big news is the claim that they can sell cultured carrot cells for cheaper than grown carrots. The 3D printing part is besides the point.

Also the carrot shape isn't really ideal for cooking. Annoying to split into smaller pieces. If you have the freedom to print it in any shape then I'd take big blocks personally. Much easier to stack, store and cut into arbitrary shapes for cooking. Molds definitely seem like a better idea for mass production than slow 3D printing.
