Siemens Introduces Additive Manufacturing Process Simulation Solution

The AM Process Simulation solution uses a digital twin to simulate the build process prior to printing, anticipating distortion within the printing process and automatically generating the corrected geometry to compensate for these distortions.

Siemens announces a new Additive Manufacturing (AM) Process Simulation solution for predicting distortion during 3D printing. The product is fully integrated into Siemens’ end-to-end AM solution, which assists manufacturers in designing and printing useful parts at scale. Building on Siemens’ comprehensive digital innovation platform and the Simcenter portfolio, the AM Process Simulation solution uses a digital twin to simulate the build process prior to printing, anticipating distortion within the printing process and automatically generating the corrected geometry to compensate for these distortions. 

Siemens’ new process simulation product is integrated into the Powder Bed Fusion Process chain in the Siemens PLM Software Additive Manufacturing portfolio and is used to predict distortion for metal printing. The product provides a guided workflow to the user that allows for the assessment of distortions, the prediction of recoater collisions, prediction of areas of overheating and other feedback about the print process. The AM Process Simulation solution offers the ability to iterate on a solution between the design and build tray setup steps of the workflow, and the simulation step. This closed feedback loop is possible due to the tightly integrated nature of the Siemens digital innovation platform. The simulation data created feeds into the digital thread of information which informs each step of the printing process. This digital backbone enables the system to develop pre-compensated models and, more importantly, to feed those seamlessly back into the model design and manufacturing processes without additional data translation. 

“This solution is the latest addition to our integrated additive manufacturing platform, which is helping customers industrialize additive manufacturing by designing and printing useful parts at scale,” says Jan Leuridan, senior vice president for Simulation and Test Solutions at Siemens PLM Software. “By using a combination of empirical and computational methods we can increase the accuracy of the simulation process, feeding the digital twin and helping customers better predict their real-world print results.”

The AM Process Simulation solution is expected to be available in January 2019, as part of the latest NX software and Simcenter 3D software.
