Sigma Labs, developer of打印机3D质量检查软件, has entered a Cooperative Research and Development Agreement (CRADA) with the U.S Department of Commerce’s National Institute of Standards and Technology (NIST).
The CRADA’s focus is to characterize and asses the impact of recycled powders used in Laser Powder Bed Fusion (LPBF) processes.
The study is reportedly the first of its kind to combine in-situ monitoring and mechanical property characterization to asses the effect of recycled powder for 3D printing.
提出加性的相关问题
Sigma的Printrite3D Technology是一个软件和数据收集平台，用于检查，反馈，数据收集和金属3D印刷组件的关键分析。应用于构建和后加工阶段，使用Printrite3D制造的部分受益于早期缺陷检测，降低废料，增加产量和精确控制。
For these reasons, the PrinteRite3D suite is especially valuable to the aerospace industry.Honeywell Aerospaceis one Sigma’s most high profile contracts.
此外，Sigma的检查专业知识与NIST添加剂制造测试台（AMMT）所做的工作完全一致。AMMT专注于LPBF，试图回答与添加剂相关的相关问题正如Nist的Brandon Lane和Steven Grantham所讨论的那样, “which measurement tools can best acquire the key physical information about the process? What do these measurements say about the quality of the AM build process? How can we determine the quality of those measurements?”
More efficient and reliable
LPBF systems are made cost and energy efficient by the ability to recycle powders. Usually, build chambers contain a mixture of recycled and fresh “virgin” powder. Recycled powder however has different properties to the virgin powder, as it has already been through the melt process.
Withprintrite3dINSPECT®软件，NIST和Sigma希望了解粉末的变化如何转化为建筑室行为和完成的3D打印零件。
研究中收集的数据将通过期刊文章与增材制造社区共享，并通过nistAM Material Database.
马克·科拉, President and Chief Technology Officer at Sigma Labs, comments, “Using our PrintRite3D technology will enhance NIST’s interlaboratory round-robin studies to provide much needed and currently unavailable scientific in-situ data on the impacts that different build layouts or recycled powder have on the LPBF AM process and its variability,”
“With this knowledge, we can help to improve the efficiency and reliability of the process so that the AM community can take full advantage of its desirable material and cost savings.”
