With the release of the VELO3D Assure™ Quality Assurance and Control System for its Sapphire® 3D metal printers, VELO3D also brings on board a heavy hitter in their first customer as Stratasys Direct Manufacturing, a subsidiary of Stratasys, Ltd., will be the first to integrate Assure into their manufacturing processes.

VELO3D’s Assure™ quality control dashboard enables engineers to track the quality and progress of Sapphire® machines in real-time.

Assure offers unprecedented monitoring and substantiation of part quality, offering the following features:

Detects process anomalies
Flags issues
Highlights necessary corrective actions
Offers traceability

“Assure is a revolutionary quality-control system, an inherent part of the VELO3D end-to-end manufacturing solution for serial production,” says Benny Buller, founder and CEO of VELO3D. “Assure is part of our vision to provide an integrated solution to produce parts by additive manufacturing with successful outcomes.”

Upon receipt of their own Sapphire 3D printer earlier this year, Stratasys Direct not only began using Assure, but they produced an entire study from their evaluation, which included:

Monitoring integrity of builds
Validating bulk material density
Observing ongoing process metrics
Verifying calibration of the system

Assure predicts defectivity as a function of layer number. An increase in the defectivity metric is correlated with increasing defectivity in the bulk core of the part.

Before and during a build, Assure validates that critical parameters stay within control limits ensuring high quality parts. Clicking on individual squares reveals details on the underlying event.

These results were published in ‘Stratasys Direct Manufacturing Performs Field Validation of VELO3D Assure™,’ after the Stratasys Direct team used Assure for 12 weeks, verifying findings produced by VELO3D. They are now using the system in ongoing production efforts.

“AM can print parts and meet requirements for single units but scaling from a single part into serial production has been challenging. OEMs lack confidence in AM process control, and AM users struggle to demonstrate it. Without visibility into each part’s deposition lifetime AM becomes a risk,” states author Andrew Carter, Sr. Manufacturing Engineer at Stratasys Direct Manufacturing.

Assure boosts manufacturing techniques for the user as they can understand tool health better, calculate part quality, and perform field validation. Engineers 3D printed test structures during their study, producing wedges measuring 20mm x 41mm in width and length respectively. The wedges could be stacked into a tower shape, making a structure to match the build z-height. For each test run, they created two towers.

Ultimately, 75 test structures were created and then analyzed via X-rays. Bulk porosity measured at 0.02 percent, and the researchers pointed out that there was no ‘single part exhibiting porosity higher than 0.1 percent. There were no deviations in print quality for the test builds.

“Stratasys Direct has built a culture of continuous improvement that means we are continually setting new standards for our industry on quality,” said Kent Firestone, CEO of Stratasys Direct Manufacturing. “We integrated Assure into our quality control workflow because it produces highly actionable insights. The user interface features intuitive graphs and charts that enable us to see and interpret the vast amount of data collected during builds. This information helps our engineers verify the quality of the build each step of the way and enables them to make quick decisions in the event of an issue. Assure helps us reduce production variation, improve yields, and circumvent anomalies to ensure consistent additive manufacturing.”
