Over the past decade 3D printing has captured the imagination of the general public, engineers and environmental visionaries. It has been hailed as both a revolution in manufacturing and an opportunity for dramatic environmental improvement.

3D printing has two key attributes that lead enthusiasts to call it a “green” technology. First, many 3D printing systems generate very little waste, unlike conventional manufacturing techniques such as injection molding, casting, stamping and cutting. Second, 3D printers in homes, stores and community centers can use digital designs to make products onsite, reducing the need to transport products to end users.
