there are 3D scanners and various rapid prototyping machines, ranging from printers to CNC machines. Though large scale printers are much rarer than large scale CNC.
If you google rapid prototyping services you'll find some companies. But it's most likely going to be much more expensive than looking if you can locate a larger version of your sculpture, particularly if yours is a popular one. A large run reproduction will always be cheaper than an unique custom fabricated item.
