| Abstract Scope |
Powder bed fusion of polymers requires the use of flow additives to ensure adequate flowability of the feedstock material. However, information regarding flow additives and their load is limited, as is understanding of their impact on processing conditions. This study investigates the flow behavior using static and dynamic measurements under process conditions, with a particular focus on the influence of flow additives. Subsequently, processing studies are conducted using thermography to analyze the laser material interaction. The characteristics of parts produced from Polypropylene and Polyamide 12 systems are also examined. The findings of this research enhance the understanding of the impact of flow additives on the processing conditions of laser-based powder bed fusion of polymers, potentially leading to optimized process parameters and improved part quality and mechanical properties. |
