Solutions and Support for Industry-Leading Manufacturing Processes

汽车和航空航天公司一直处于持续的竞争,以提高能源效率和设计灵活性,降低生产和服务成本,并减少制造周期时间,同时确保其产品的可靠性和安全性。betway手机客户端下载对于许多这些公司来说,增材制造业(AM)看起来像是所有这些市场需求的解决方案。最快的新兴金属和流行的AM工艺是基于粉末床的:金属粉是通过熔化或烧结形成的固态。常见的熔化技术包括扫描激光(直接激光选择性熔化,DLSM)或电子束(电子束熔化-EBM),然后在“打印机”粉末床中跨后续金属粉末层,以建立最终的最终部分,完成AM。该技术也称为粉末床融合或LPBF。另一种AM技术是增值税光聚合,占AM中材料使用的近50%。增值税光聚合是一个过程,在该过程中,通过光激活的聚合能够选择性地固化液体光聚合物。

However, many companies find that the move from prototyping to production with AM is challenging. To get defect-free, repeatable results requires process characterization and QA/QC controls that are unique to AM. Bruker has unmatched experience and breadth of solutions to help maximize AM Profits.

正确指定和监视AM过程中使用的原材料的化学和机械性能绝对至关重要。必威手机客户端夹杂物,空隙,孔隙率变化以及变化是机械性能(硬度,脆性)可能是由于合金/混合物的使用不当以及对传入,储存和再生粉末的污染而导致的。

AM打印过程本身,即使没有正确的表征,也可能是各种缺陷的来源。在扫描速度,激光或电子束功率,光束入射角,周围粉末床的热负载,粉末粒径和床厚度之间需要找到最佳的平衡。对于增值税光聚合,不仅混合物组成,而且光聚合物的固化动力学对于结果至关重要。为了表征AM过程并在生产过程中和完成步骤后(热处理,铣削和研磨/抛光,紫外线固化)进行监测证人样本,Bruker提供了无与伦比的产品套件,用于尺寸,化学和机械测试和分析。
