PPG Produces 3D-Printed Ramp Seals for Lockheed Martin C-130J Super Hercules
The ramp seals are PPG’s first commercial sale of 3D-printed components.
PPG recently announced that it has supplied Lockheed Martin with sets of six custom-designed ramp seals for the aft loading ramp of the C-130J Super Hercules military tactical airlifter. This is PPG’s first commercial sale of 3D-printed components.
PPG reports that it created the ramp seals via additive manufacturing using a patented ambient reactive extrusion (ARE) technology called PPG ARE that results in easy-to-install parts made from PPG’s production-qualified aerospace sealant. The 3D-printing process enables PPG to customize the design of various parts, such as ramp seals, for continuous process improvement while increasing sustainability.
