The Scotty Sphere

Crafted personally for you, the intricate design of the Scotty Sphere took shape layer-by-layer through the process of additive manufacturing, also known as 3-D printing. Its interlocking geometry showcases the disruptive technology used today in 3-D printed airplane parts and medical implants. As you turn the sphere over, you will see a symbol of our CMU pride. The Scotty Sphere is a fitting testament to CMU’s strengths in research and innovation. 

The additive process used to create the Scotty Sphere is catching fire across industries like aerospace, automotive, biomedical and energy. The unique technology has the potential to reduce waste, decrease time to market, increase product performance and promote product innovation. At CMU, we have a deep history in 3-D printing: one of the first metal objects produced using direct-metal additive manufacturing was created right here in Hamerschlag Hall in 1990. Since then, the College of Engineering has been working at the forefront of the field to shape and improve 3-D printing technology and techniques. 

Our NextManufacturing Center, one of the world’s leading 3-D printing research centers, leverages knowledge from across disciplines to perform cutting-edge research, while also educating and training the next generation of experts through creative, hands-on problem-solving. In fact, CMU is the only university in the United States to offer metal additives manufacturing to undergraduate students.

As the field of additive manufacturing rapidly develops, we are committed to helping our students gain essential skills through hands-on problem solving and research. Please enjoy this sphere as a reminder of the progress we have made and will continue to make here at Carnegie Mellon.
