Boeing has introduced a 3D-printed solar array substrate designed to shorten spacecraft production timelines by up to six months. The technology, developed within Boeing’s Space Mission Systems organization, aims to reduce build times for solar array wings by approximately 50 percent compared with current processes.
Flight-representative hardware has completed engineering testing and is undergoing Boeing’s qualification process before entering customer missions. The first 3D-printed arrays will carry Spectrolab solar cells aboard small satellites produced by Millennium Space Systems, both subsidiaries of Boeing.
The new manufacturing method prints harness paths, attachment points, and other features directly into each panel, consolidating what had previously required dozens of separate parts and bonding steps. By combining a rigid printed substrate with modular solar technologies, Boeing enables parallel production of array structures and solar cells. To further accelerate output, robot-assisted assembly and automated inspection are being implemented at Spectrolab’s facilities.
Boeing stated that the approach builds on its experience with additive manufacturing, which has already produced more than 150,000 3D-printed parts across its aerospace programs. These include over 1,000 radio-frequency components on each Wideband Global SATCOM satellite and fully printed structures in several small satellite product lines. The solar array platform is intended to scale from small satellites to larger Boeing 702-class spacecraft, with initial market availability targeted for 2026.
