3Diligent Worked with Walters & Wolf from Prototype Through Production; Provided 3D Printing of 140 Unique Aluminum Nodes in Varying Dimensions
El Segundo, Calif.—March 6, 2019—3Diligent announced today that Walters & Wolf, a commercial cladding company, engaged 3Diligent to manufacture 140 unique exterior curtain wall nodes that Walters & Wolf designed to deliver the iconic exterior look and feel of the upcoming Rainier Square Tower in Seattle.
Expected to be finished in 2020, the new Rainier Square Tower will become Seattle’s second-tallest building. The structure will be a 58-story tower with a unique sloping appearance. With a step back on each building floor, the cladding system for each floor will have a different angle and require complex geometries to fit together perfectly.
Walters & Wolf worked with 3Diligent from prototype through production to produce 140 unique nodes with varying dimensions up to nearly a cubic foot in size. As geometries changed throughout the building’s design, 3Diligent leveraged its deep metal 3D printing expertise to ensure each unique geometry met Walters & Wolf’s exacting specifications.
“From an operations standpoint, we were impressed with 3Diligent’s consistency in the delivery of highly accurate and complex parts in a timely fashion that was in sync with the production schedule we established early on,” said Tony Parker, Project Executive at Walters & Wolf. “At the end of the day, 3Diligent upheld their end of the bargain—they simply did what they said they would do.”
3D Printing of Challenging Geometries
Each piece of the curtain wall needed to be custom fabricated to meet the unique geometry of that section of the building. Walters & Wolf determined the best approach would be to create V-shaped nodes ranging in size that would bring together square-cut parts of the curtain wall. After experimenting with a variety of manufacturing processes and having some vendors say they couldn’t complete the work, Walters & Wolf turned to 3Diligent.
3Diligent presented two manufacturing processes—investment casting and 3D printing—and delivered first articles from the different processes. These were assembled into curtain-wall units and sent for performance mock-up testing. After testing, Walters & Wolf selected 3D printing as their preferred path forward.
“We were honored when Walters & Wolf engaged 3Diligent as its manufacturing partner for this project,” said Cullen Hilkene, CEO of 3Diligent. “Both the tower and these specific parts represent the sort of innovation that 3Diligent strives to enable every day. It was great collaborating with Walters & Wolf on such a compelling project and we look forward to seeing the completed tower in 2020!”
