This in-situ inspection technology is intended to support the EOS M 400 series of machines and other large-format platforms such as the Nikon SLM NXG product line. Both Phase3D machines can also be retrofitted to be compatible with Additive Manufacturing machines featuring build areas up to 600 × 600 mm.

Fringe Inspection is an in-situ structured light inspection machine that delivers unit-based, quantitative measurements during the Additive Manufacturing process. Using structured light projection and proprietary calibration, the systems achieve ±10 µm vertical accuracy, 60 µm spatial resolution, and repeatability of 5 µm at the calibration plane. These measurements provide real-time information on layer height, deposition consistency, and melt surface quality, all critical for detecting anomalies such as short feeds, chatter, protrusions, over-melting, and recoater interference.
