What Phase3D does
Phase3D is a Chicago-based hardware and software company developing in-situ quality inspection systems for metal additive manufacturing. Its core product, Fringe Inspection, is a proprietary structured-light heightmap sensor that captures real-time, unit-based measurements layer-by-layer during metal powder bed fusion (LPBF) 3D printing, enabling defect detection without interrupting the build process. In November 2025, the company launched two large-format variants of its inspection systems to support large 3D printers used in aerospace applications, extending the product line beyond the original Fringe Inspection sensor.
The company serves 25 enterprise customers across aerospace, defense, and industrial sectors, including active collaborations with NASA, the U.S. Air Force, the U.S. Navy, and three U.S. national laboratories (Argonne, Oak Ridge, Los Alamos), plus an unnamed aerospace prime contractor that has adopted the large-format systems. Its go-to-market is direct enterprise field sales targeting regulated, high-value accounts, with revenue generated through hardware sales of inspection systems bundled with associated software. The company was founded in 2020, operates with 1–10 employees, and is led by founder and CEO Niall O'Dowd. In 2026, Phase3D closed a $2.9 million oversubscribed seed round led by Quest Venture Partners, with proceeds earmarked for scaled manufacturing of Fringe Inspection and expansion of software and data science capabilities.
