Among the literature recently indexed by the National Science and Technology Library (NSTL), a study by Xu Lili and Li Jingwei published in Aerospace Materials & Technology, 2026 Issue 2, focuses on a 3D-printed satellite engine mount flange and upper joint, manufactured from AlSi10Mg aluminum alloy using laser melting technology. The parts were evaluated through mechanical property testing of furnace-following specimens, X-ray and fluorescent inspection, adhesive tensile shear strength testing, tube shear tests, and high-temperature static loading tests. The results show that the vibration test data of the 3D-printed joint bracket and engine assembly are superior to those of the old braided joint bracket, and the high-temperature tube shear failure load is significantly higher than the qualification-level load. Another study indexed in the same period focuses on a lightweight satellite engine mount base plate, using TC4 titanium alloy for laser additive manufacturing, with emphasis on optimizing laser processing parameters and forming processes; the base plate was additively manufactured and passed mechanical test evaluation. The two works cover aluminum alloy and titanium alloy material routes respectively, verifying the process feasibility of laser additive manufacturing for satellite load-bearing structural components, with inspection covering internal quality, bonding quality, and structural stability. For the metal additive manufacturing supply chain, load-bearing parts such as satellite engine mounts have high requirements for powder batch consistency, oxygen content, and sphericity; the stable supply capability of AlSi10Mg and TC4 powders directly determines the mechanical performance of formed parts. The comparative data between furnace-following specimens and qualification-level loads in the literature provide a reference acceptance approach for powder buyers evaluating supplier batch stability. Value for powder buyers: 1) Focus on batch consistency of AlSi10Mg and TC4 powders and require suppliers to provide mechanical data for furnace-following specimens; 2) Include oxygen content and sphericity in incoming inspection indicators to match the powder flowability requirements of laser melting processes; 3) Prioritize powder manufacturers with a supply record for aerospace load-bearing parts to reduce process validation risks.
