This chapter investigates the effects of thermal and temporal influences on the resulting part properties, particularly the temperature profile in the powder bed fusion process with a laser beam for polymers (PBF-LB/P). Through detailed process analysis, new strategies have been developed to increase the robustness of the process, control thermal history, and improve part quality while promoting sustainability and productivity. Key insights are provided into the heating and powder coating processes, which are critical constraints for achieving uniform part properties with minimal material variation. Furthermore, a non-isothermal PBF approach is presented for processing materials that are not traditionally suitable for PBF.

摘要

This chapter investigates the effects of thermal and temporal influences on the resulting part properties, particularly the temperature profile in the powder bed fusion process with a laser beam for polymers (PBF-LB/P). Through detailed process analysis, new strategies have been developed to increase the robustness of the process, control thermal history, and improve part quality while promoting sustainability and productivity. Key insights are provided into the heating and powder coating processes, which are critical constraints for achieving uniform part properties with minimal material variation. Furthermore, a non-isothermal PBF approach is presented for processing materials that are not traditionally suitable for PBF.
