Perhaps in the short run, but definitely, not in the long run! With a 3D printer, it is much faster to produce something and in large quantities. Also, by using a 3D printer, it'll be much cleaner and you can easily configure how big you want a certain model to be printed.
Also, one enormous benefit of using a 3D printer is that human error can be greatly reduced! This is why many industries are turning to 3D printing.
