Improving Metrology in Additive Manufacturing https://ift.tt/2Nj16r0 International researchers explore the role of additive manufacturing for geometrical measurements, along with current requirements and the potential for future research. Their findings are outlined in ‘Geometrical Metrology for metal additive manufacturing,’ as the researchers explain what an impact 3D printing and AM processes will continue to have in the world of manufacturing, including everyone from the DIY user with a workshop in the garage, to those running enormous factories. Geometric metrology benefits from 3D printing technology due to latitude in the creation of more complex geometries—with impressive impacts being seen already despite the relative youth of AM. While conventional techniques still rule the manufacturing world, AM continues to show greater promise.
Further benefits include:
Along with that, the researchers list the following identified ‘medium to high priority standardization gaps:’
Geometric tolerancing is ‘critical,’ in terms of inspections, and the researchers present concerns regarding AM design content with existing standards and the presence of features like lattices and cellular materials—along with customized textures and graded parts. Other research efforts have focused on meeting some of the challenges presented in both pre- and post-processing, along with efforts to produce smoother surfaces and avoid systematic errors, occlusions, and other issues. Research is underway to both maximize object coverage whilst at the same time minimizing both measuring time and the amount of manual intervention in the measurement planning. Integrating methods from artificial intelligence into the measurement process is showing promise but requires much more research into measurement automation, versatility, and traceability,” concluded the researchers.
And although 3D printing and metrology may sound like a more complex mix than some research and development entails today, other companies are instilling additive manufacturing processes in their companies with great success, as well as consulting with others on critical projects like 3D scanning and preserving historical items, creating comprehensive metrology labs, and further examining effectiveness.
