Challenges of Post-Processing in L-PBF

The primary goal of Laser Powder Bed Fusion (L-PBF) technology is to create intricate and complex 3D printed parts. Within this process, residual powder is produced. The powder must be carefully cleaned to ensure the integrity, value, and look of the final product. The presence of unremoved powder may result in internal stress areas, decreased mechanical properties, and an unfinished surface appearance. Additionally, it is crucial not to overlook the safety and environmental implications of handling and disposing of metallic powders, especially those that are highly reactive

Statistical data and industrial research demonstrate the economic ramifications of ineffective post-processing. In severe cases, trapped powder may constitute up to 20% of a parts weight. For example, if a part weighs 60 kilograms, it could contain 12 kilograms of powder trapped within internal channels. Given the high cost of metal powders used in L-PBF, inefficiency can have a significant financial impact. This is where Addiblast depowdering solutions come into play. Our machines effectively remove all trapped powder from complex channels, reducing costs, time, and the need for manual labor.
