Monitoring system designed for LPBF 3D printers

The startup Additive Assurance has introduced AMiRIS, an in-situ process-monitoring system for laser powder bed fusion (LPBF) metal additive manufacturing. Compatible with most LPBF printers, according to the company, it provides QA reporting across a fleet of machines and machine types.

The patent-pending technology combines a suite of optical sensors that gather micron-level details about a build, then, through machine learning, generates data about the process.

The agnostic system reportedly:

• Knows immediately when a build is nonconforming. Real-time feedback shows defects as soon as they occur and offers the option to automatically stop a build that surpasses a user-set defect threshold.

• Offers standardized quality tracking and reporting independent of machine type and location. This ensures distributed supply chains are producing components to specification, regardless of location.

• Ensures part conformance in-process, reducing the time from print to in-field deployment.
