Phase3D Releases Fringe Inspection Systems

Phase3D has released two new large-format Fringe Inspection Systems for metal additive manufacturing. The 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. Both can be retrofitted to additional machines with build areas up to 600x600 mm.

Fringe Inspection is an in-situ structured light inspection system that delivers unit-based, quantitative measurements during the additive process. Using structured light projection and 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.

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.

Enabling Delta Qualification

The Large-Format Fringe Inspection Systems introduce a capability for delta qualification across additive manufacturing platforms. Using deterministic heightmap data, AM users can now compare print and part quality between single- and multi-laser systems of different brands and build sizes without requiring full requalification campaigns.

This approach enables organizations to demonstrate process equivalency and machine conformance through direct, unit-based measurement. The result is a path toward cross-platform qualification.

Enabling Standards-Based Qualification

The large-format Fringe Inspection™ systems integrate with Fringe Qualification™ software for deterministic data analysis, traceable reporting, and automated anomaly documentation. All measurements are NIST-traceable, making the systems suitable for quality assurance and qualification frameworks across aerospace, defense, and industrial applications.
