World’s Largest 3D Printed Structure in the Spotlight at Super Bowl LVIII

Super Bowl Sunday is quickly coming up! This Sunday, the Chiefs vs. 49ers showdown will kick off at the Allegiant Stadium for Super Bowl LVIII, and, in an event characterized by hype due to factors like the romance between Travis Kelce (a tight end for the Chiefs) and Taylor Swift, and Usher’s upcoming performance, it would be understandable if you had missed the fact that 3D printing will have its own role to play! The world’s largest freestanding, 3D printed structure, made in honor of the late Al Davis, the long-time franchise owner of the Las Vegas Raiders, is on display in the stadium. This incredible torch is set to symbolize the convergence of sports, technology, and remembrance and can be expected to captivate the attention of millions nationwide as they gather to watch the final game of the season.

But what exactly is this 3D printed structure? Crafted by the design, build, and tech firm Dimensional Innovations, this monumental tribute, known as the Al Davis Memorial Torch, is not only a testament to Davis’s legacy but also a marvel of modern engineering and additive manufacturing. Standing at an impressive 93 feet or nine stories tall, the Al Davis Memorial Torch constitutes the world’s tallest 3D printed structure, by both volume and height. Weighing over 40 tons, nearly 50,000 hours went into its design and construction.

The torch is composed of 226 3D printed blocks, each meticulously crafted from carbon fiber-reinforced polycarbonate composite. These blocks, weighing approximately 350 pounds each, were printed using one of only three Large Scale Additive Manufacturing (LSAM) machines available in the United States, which Dimensional Innovations acquired in 2019 to begin construction.
