Printing aviation parts on a 3D printer can be tricky and downright dangerous. The slightest defect is critical to the safety of the technology.
This problem is especially problematic in the creation of high-tech parts for the aviation and space industries where aluminum 3D printing is commonly used and where the slightest defect is critical to the safety of the technology.
A common issue is that small holes and cavities can form within the part. High residual porosity can result in low density and potential cracks and can be brought on by a range of factors, including the quality and size distribution of the initial material, the incorrect printing parameters and residual gases in powders.
