Residual stress control in large format polylactic acid additivemanufacturing via fast thermomechanical simulation andin-operando imaging techniques

Key Points

• Residual stress control enhances the quality of large format polylactic acid parts, enabling better structural integrity.
• Observed variations in residual stress during fast thermomechanical simulation, impacting manufacturing outcomes.
• Assessment using in-operando imaging techniques facilitates real-time monitoring of stress during the process.
• Highlights the need for integrated approaches to optimize additive manufacturing techniques and minimize deformation.
