3D 打印行业系列专家会议 - 3D 打印在商业航天的发展现 状与未来展望 20260108 摘要 3D 打印在液体火箭发动机制造中作用显著，尤其在可重复使用发动机的 复杂结构（如冷却流道）制造上，能提高材料利用率并缩短生产周期， 降低对传统高端工艺和大国工匠的依赖。 液体火箭发动机中 3D 打印零件的价值占比接近一半，国外先进发动机 甚至高达 80%-90%，表明 3D 打印在火箭制造中具有巨大的成本和效 率优势，并可能进一步提升。 国内商业航天企业在火箭和发动机制造中广泛采用 3D 打印技术，渗透 率高，尤其是在发动机制造领域，约 90%的企业考虑使用，以应对传统 工艺难以实现的设计。 当前主流火箭发动机制造采用选择性激光熔融（SLM）工艺，能提供较 好的表面质量，简化后处理流程，主要使用高温合金、不锈钢和铜合金 等材料。 火箭发动机和储箱是火箭制造中成本最高的部件，3D 打印在发动机制造 中的成本占比可达一半左右，随着技术成熟和批量化生产，成本有望进 一步降低。 Q&A 3D 打印技术在商业航天中的应用现状及未来展望如何？ 目前，3D 打印技术在商业航天领域的应用主要集中在液体火箭发动机的生产上。 由于 ...

中新网天津12月4日电 题：国家设立商业航天司，天津如何竞逐"星"赛道？ 中新网记者 王君妍 周亚强 随着国家航天局设立商业航天司并出台专项行动计划，我国商业航天产业迈入"规范发展期"，也预示着 一条涵盖卫星制造、火箭发射、地面站及终端设备、运营与应用服务等环节的产业链或走上发展"快车 道"。 当前，京津冀、长三角、珠三角已形成三大商业航天产业集群，多个省市密集出台支持举措，在政策东 风频吹下，竞逐商业航天"星"赛道。 11月30日20时20分，中国在文昌航天发射场使用长征七号改运载火箭，成功将实践二十八号卫星发射升 空，卫星顺利进入预定轨道，发射任务获得圆满成功。图为长征七号改运载火箭点火瞬间。 记者 骆云 飞 摄 天津在这场"太空竞赛"中起步较早。2006年，天津港保税区开始布局航空航天产业；2007年，中国新一 代运载火箭产业化基地在天津滨海新区开工建设。面对国家层面的新一轮战略部署，天津如何抢抓机 遇，推动商业航天从"先行"迈向"领跑"？ 火箭发射："国家队"与民营企业协同并进 火箭发射能力是商业航天发展的关键一环。天津在这一领域既拥有"国家队"支撑，也涌现出一批深耕细 分领域的民营企业，构建起多元协 ...
