Cad-1Big Blue Saw is a new site that lets you create parts out of metal or plastic. You use your favorite CAD program to design a part, then upload the design to their site to get a rendered 3D image, and a quote. From the site: “Big Blue Saw is a new concept which brings together the Internet with modern computer controlled rapid manufacturing. With Big Blue Saw, takes a design you have made on your computer, then turns that design into a objects using state of the art robotic machine tools. Your parts are delivered right to your door.” Link.
