Process-Monitoring Software for AM

July 18, 2018


Renishaw introduces its InfiniAM Spectral, a new additive-manufacturing (AM) process-monitoring software part of a developing family of products that help users capture, evaluate, present and store process data from Renishaw laser powder-bed fusion technologies.

The software, to formally debut at IMTS 2018 this September in Chicago, IL, helps AM users gain a greater understanding of their processes and overcome the difficulties with AM in critical applications, process stability and part quality, according to company officials. The new software offers two measurement functions in the sensor modules. The first module, LaserView, uses a photosensitive diode to measure the intensity of the laser energy. The second module, MeltView, captures emissions from the melt pool in the near-infrared and infrared spectral ranges.

The modules stream data across a conventional computer network on a layer-by-layer basis, allowing manufacturers to analyze process-monitoring data in real-time. As the build progresses, the data are rendered live in 3D for viewing in InfiniAM Spectral. Engineers can compare the data from each sensor to identify any deviations, which may indicate the presence of anomalies that could lead to defects.

“The amount of process data generated during an AM build is immense, which means it can be difficult to make practical use of it without the correct interpretation tools,” explains Robin Weston, marketing manager at Renishaw’s Additive Manufacturing Products division. “InfiniAM Spectral will be beneficial to manufacturers because it allows them to easily translate the data. That will lead to more consistent AM outcomes.”
