Additive Manufacturing

It all started in the 1960s as science fiction in Star Trek. A person asked the computer to replicate a part or object, and the computer did — without the challenges that we’re familiar with today, such as casting and milling. Today, additive manufacturing goes beyond simply replicating an existing object. It offers new functionality and efficiency during manufacturing.
Nevertheless, these technological changes require that we relearn or even reinvent a lot of engineering common sense. The limits of what is possible change with every new iteration of additive manufacturing.
