Enhancing Mechanical Properties of PA12 in Powder Bed Fusion Additive Manufacturing ID: 2022-004

This study examines how different Powder Bed Fusion Additive Manufacturing processes affect the mechanical properties of Polyamide 12 parts.

Technology Overview

The document provides an in-depth comparison of mechanical properties such as density, ductility, and crystallinity in Polyamide 12 (PA12) parts produced through laser powder bed fusion (L-PBF), multi-jet fusion (MJF), and large area projection sintering (LAPS) methods. It highlights the superior ductility and density achieved by LAPS due to high-temperature maintenance during printing, facilitating better chain growth and entanglement.

Key Advantages

• Identification of LAPS as a superior method for achieving high-density and ductile PA12 parts
• Insight into the role of heat treatments in enhancing ductility across different PBFAM processes
• Understanding the limitations of density as a sole predictor of mechanical properties in PA12 parts

Problems Addressed

• Improvement of mechanical properties in PA12 parts for additive manufacturing
• Overcoming the limitations of "end-capping" in MJF polymer powders that inhibit chain growth
• Challenges in predicting mechanical properties based solely on part densities

Market Applications

• Development of more durable and resilient parts for aerospace, automotive, and medical industries
• Enhancement of additive manufacturing processes for better material performance
• Potential for broad market implementation in commercial additive manufacturing technologies
