In January, SpaceX first flew a "Falcon 9 rocket with a 3D-printed Main Oxidizer Valve (MOV) body in one of the nine Merlin 1D engines". The valve is used to control flow of cryogenic liquid oxygen to the engine in a high-pressure, low-temperature, high-vibration physical environment.〔 Other 3D-printed spacecraft assemblies have been ground-tested, but have not yet flown to space, including high-temperature, high-pressure rocket engine combustion chambers and the entire mechanical spaceframe and propellant tanks for a small satellite of a few hundred kilograms. The new United Launch Alliance Vulcan launch vehicle—with first launch no earlier than 2019—is evaluating 3d-printing for over 150 parts: 100 polymer and 50+ metal parts.〔 〕 ==Applications== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「3D-printed spacecraft」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
