Boeing and Thermwood employed AM technology to produce a large, single-piece tool for the 777X program. Thermwood used a Large Scale Additive Manufacturing (LSAM) machine and Vertical Layer Print (VLP) 3D printing technology to fabricate the tool as a one-piece print, eliminating the additional cost and schedule required for assembly of multiple 3D printed tooling components.
