The　additive　manufacturing　technology　has　the　advantage　of　rapid　manufacturing　of　single-piece　and　small-batch　complex　structures　used　in　aerospace　applications,　and　integration　of　design,　materials　and　manufacturing　will　be　the　direction　for　its　future　development.　This　paper　analyzes　three　aspects　of　application　and　development　of　additive　manufacturing　in　the　field　of　aerospace,　focusing　on　the　manufacturing　of　aero-engine　turbine　blades,　high-performance　Poly-Ether-Ether-Ketone　(PEEK)　and　its　composites,　continuous　fiber　reinforced　resin　composites,　and　space　3D　printing.　The　research　status　of　additive　manufacturing　technology　at　home　and　abroad　and　in　Xi＇an　Jiaotong　University　is　also　introduced.　The　application　of　additive　manufacturing　technology　for　turbine　blades　can　effectively　improve　the　manufacturing　efficiency　and　reduce　costs.　In　the　future,　this　technology　can　meet　the　manufacturing　of　high-performance　superalloy　and　ceramic　matrix　composite　blades.　The　additive　manufacturing　of　high-performance　lightweight　polymer　PEEK　and　its　composites　are　applied　in　forming　of　structure　parts　with　high　mechanical　properties　and　radio　absorbing　functional　parts,　which　will　change　the　existing　design　and　materials　and　promote　the　integrated　development　of　structure　and　function.　The　additive　manufacturing　of　continuous　fiber　reinforced　resin　composites　will　drive　the　new　development　of　forming　of　moldless　fiber　composites,　and　3D　printing　in　space　will　change　the　aerospace　manufacturing　model　in　the　future.　The　additive　manufacturing　technology　will　revolutionize　the　aerospace　manufacturing　technology.　©　2022,　Beihang　University　Aerospace　Knowledge　Press.　All　right　reserved.
