With sand casting you still need a mold to form the sand. These molds aren’t easy to make, especially quickly. With this 3d printer, you can go from design to finished product long before the mold is constructed.
In terms of speed, you’re totally right. That said, thete are tons of methods of turning a plastic 3D printed part into a metal part via sand casting that you can do at home. With enough money, evidently you can skip the plastic stage completely: https://www.exone.com/en-US/parts-and-services/sand
Its not better probably, but I would rather have printed one because its more cool lol
Seriously, casting have its own geometry limits compared to printing.
Well, I watched a video after writing that, so my post is bit stupid. It probably doesnt apply for single layer shapes like ones shown on the video, but it looks faster than sand casting. Adding Z axis would make it more powerfull tho
So explain how this is better than sand casting? Which doesn’t need glass particles and can provide much better surface finish?

There are also things that can be 3d printed that can’t be easily cast, like things with oddly-shaped holes, and hollow objects.
This is the same as asking why 3d print something when injection molding exists.
