Phase3D Extends In-Situ Fringe Inspection to Large-Format Metal AM Systems
Phase3D has announced the release of two new large-format Fringe Inspection Systems for metal additive manufacturing. The new systems, Large Format Fringe Inspection and Large Format Fringe Inspection Hi-Rez, extend Phase3D’s in-situ inspection technology to support the EOS M 400 series of printers and other large-format platforms such as the Nikon SLM NXG product line. Both can be retrofitted to additional machines with build areas up to 600 x 600 millimeters.
Fringe Inspection is the industry’s only in-situ structured light inspection system that delivers unit-based, quantitative measurements during the additive 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 insight into layer height, deposition consistency, and melt surface quality, all critical for detecting anomalies such as short feeds, chatter, protrusions, over-melting, and recoater interference.
Expanded Capability for Large-Format Systems
Phase3D now offers two configurations tailored to the needs of large-format additive users:
- Large Format Fringe Inspection – 100 µm pixel size for production environments
- Large Format Fringe Inspection Hi-Rez – 60 µm pixel size for advanced, data-driven R&D
Both configurations provide full build plate coverage for large laser powder bed fusion systems while maintaining NIST-traceable calibration and optimized performance for speed, repeatability, and integration flexibility.
Phase3D has recently published and presented results showing a causal link between in-situ layerwise surface roughness measurements and specimen density, enabling immediate prediction of final part quality based on porosity. This discovery allows manufacturers to connect in-situ data directly to part integrity and accelerate qualification workflows with confidence.
