Automation

Over the past five years, 3D printing has continued to shift from prototyping and small batch production to a mass customization production technology. All major industrial and non-industrial 3D printer OEMs are now striving to integrate their systems into complete end-to-end workflows. While the additive manufacturing process remains the core part of digital production, automating the end-to-end workflow goes well beyond the AM process itself.

It begins with automating and streamlining part design and optimization for AM through DfAM tools, which continues through digital warehouses and digital twins. Designs converge with automated material supply lines for material (for powders, pastes, resins or fibers) handling, as manufacturing execution software (MES) brings together and coordinates 3D printer networks and workflow stations.

Simulation and process monitoring software oversee the AM process all the way to the measurement and NDT, phases recognizing and even correcting errors via machine learning and AI. Robots remove parts from the print platform, as excess materials are recycled and reused. Automated post-processing equipment sinter, heat-treat, cure, polish and smooth surfaces until you get a final, digitally and additively manufactured part. With minimal human intervention. This is the vision. Where do we stand now?Those who build the infrastructure for the digital, additive, automated factory of tomorrow will be at the forefront of the ongoing industrial revolution and additive manufacturing systems are increasingly going to be the core elements within any credible industry 4.0 approach. In this month’s AM Focus, we will look at the latest trends in additive manufacturing automation.
