Phase3D Unveils Large-Format Fringe Inspection Systems: Elevating Metal 3D Printing Quality Control

November 19, 2025 – Phase3D, a pioneering company in additive manufacturing quality control, has announced the release of two new large-format Fringe Inspection Systems for metal 3D printing technology. This development marks a significant stride in ensuring the quality and reliability of metal parts produced through additive manufacturing, especially for demanding applications in aerospace, defense, and medical industries. For investors, managers, and technical experts, understanding this technology is key to optimizing production processes and mitigating risks.

Phase3D's Fringe Inspection system utilizes advanced structured light technology to provide unit-based, quantitative measurements during the printing process, offering unprecedented insight into the quality of each material layer. This not only aids in early anomaly detection but also opens up the possibility of predicting the final product quality, thereby accelerating certification processes and significantly reducing production costs.

Fringe Inspection Technology: Superior Accuracy and Anomaly Detection

Fringe Inspection is an in-situ structured light inspection system designed to deliver unit-based, quantitative measurements throughout the additive manufacturing process. This technology employs structured light projection and proprietary calibrated optics to achieve exceptional accuracy:

• Vertical Accuracy: ±10 µm
• Spatial Resolution: 60 µm
• Repeatability: 5 µm at the calibration plane

These measurements provide real-time, layer-by-layer insight into layer height, deposition consistency, and melt surface quality. This is critically important for detecting anomalies such as short feeds, chatter, protrusions, over-melting, and recoater interference – factors that can lead to structural failures in the final part.

Phase3D has published research results demonstrating a causal link between in-situ layerwise surface roughness measurements and specimen density. This discovery allows manufacturers to immediately predict final part quality based on porosity, thereby directly connecting in-situ data to part integrity and accelerating qualification workflows with confidence.

Efficiency in Delta Qualification and Cross-Platform Quality Assurance

These new large-format Fringe Inspection Systems introduce a novel capability for efficient 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 measurements, significantly reducing qualification timelines and costs.

The result is a path toward cross-platform qualification, allowing production to move seamlessly between machines while maintaining assurance of dimensional and material integrity. This is particularly crucial in industries like aerospace, where quality standards are extremely stringent and certification costs can be very high. Compliance with standards such as SAE AMS7032 becomes more achievable due to the ability to collect precise and reliable data.

Practical Applications and Industry Impact

An aerospace prime contractor has adopted the large-format system to address challenges in CT scanning of large, dense metal components – a process often limited by material attenuation and complex geometry. By using Fringe Inspection, the customer is leveraging in-situ height-based data to verify build quality and mitigate CT requirements. In the next phase, the same dataset will support qualification and certification efforts, correlating layer-wise measurement data with mechanical performance and ensuring compliance with standards such as SAE AMS7032.

This development has profound implications for the metal additive manufacturing industry:

• Reduced Costs and Time: The ability to detect defects early and qualify efficiently significantly reduces material waste, rework time, and time-to-market.
• Enhanced Reliability: Layer-by-layer quality control ensures higher reliability for 3D printed parts, expanding the application of this technology in critical sectors.
• Expanded Manufacturing Capabilities: With the ability to inspect large-format parts, this technology extends the scope of metal 3D printing to larger structures and components.
• Promoting Automation: Real-time, quantitative data forms the foundation for automating quality control processes, reducing reliance on manual inspection and human error.

This technology is particularly useful for manufacturing complex, high-precision parts, such as aircraft engine components or medical implants. It can also support the production of products from aluminum sheets 1050, 3003, 5052, 6061, 7075 using 3D printing methods, ensuring consistent and reliable quality.

Conclusion

Phase3D's launch of large-format Fringe Inspection Systems represents a significant advancement in enhancing quality control capabilities in metal 3D printing. By providing precise, quantitative, and real-time measurements, this technology not only aids in early anomaly detection but also accelerates certification processes and reduces costs. This will drive broader adoption of metal additive manufacturing in demanding industries, opening new opportunities for innovation and efficiency in production.
