The speaker mentions an architecture firm that commissioned the printing of a large, single-piece item. The exact nature of the item isn't specified, but its size and the fact that it required the capabilities of a large-format 3D printer (the Arntorm Giga) highlight its specialized nature.
This video offers a perspective on how to make money through 3D printing, challenging the common notion that it's a low-profit endeavor due to high competition and readily available resources. The speaker argues that focusing on specialized, business-to-business (B2B) products, rather than mass-market items, offers a more lucrative path.
