详细介绍了增材制造（AM）铝合金排气率的研究方案。增材制造在地面和天基仪器的应用中具有显著的潜在优势，特别是在批量优化、零件整合和增加设计自由度方面。然而，由于缺乏遗产和对材料的不完全理解，它在高风险项目中的使用往往受到限制。该方案的目标是解决阻碍增材制造技术在低温和天基应用中更广泛采用的最重要主题之一；材料放气的不确定性。研究了放气速率对打印方法、后处理和几何复杂度等关键参数的敏感性。通过x射线计算机断层扫描和轮廓术，研究了放气速率与其他可测量特性（如样品孔隙率和表面粗糙度）的相关性。最后，讨论了测试设备、实验设计以及研究结果对设计和过程控制的意义。
Details of a programme to investigate the outgassing rate of additively manufactured (AM) aluminium alloys are presented. AM has significant potential benefits to applications in ground- and space-based instrumentation, particularly in mass optimisation, part consolidation and increased design freedom. However, its use in high-risk projects is often curtailed by lack of heritage and an imperfect understanding of the materials. The programme goal was to address one of the most significant topics preventing wider adoption of AM technology in cryogenic and space-based applications; uncertainty about material outgassing. The sensitivity of outgassing rates to various key parameters was characterised, including print method, post-processing and geometrical complexity. Correlation of outgassing rates against other measurable properties, such as sample porosity and surface roughness, was also investigated via the use of X-ray computed tomography and profilometry. Finally, the test apparatus, experimental design and implications of the findings on design and process control are discussed.
