I am running a round robin test (from August to December 2018) of 3 selected parts in Ti6Al4V and fixed microCT test guidelines and processing workflow - the aim is to check that all participants get the same information from microCT scans of these known test parts. If any discrepancies we will explain the reason behind it. It is a relatively simple procedure clearly outlined and each participant has max 2 weeks. We would like to have a wide spread across industry and academia, please contact me if you have an interest and would like to take part.
You need
1. A microCT scanner that can go up to 200kV
2. Good image analysis software, preferably VGSTUDIO MAX, but others OK if you figure out the required modifications to the workflow yourself
3. Able to do scans and processing within a 2 week period, free of charge, and send the parts on the to next participant
Please send me a message for more detailed information
Thanks
Dear Anton,
It is nice to hear that you are planning to conduct a round robin test to standardize micro CT testing for Additive Manufacturing. I believe this is an important issue and will contribute to additive manufacturing qualifications both for research institutes and companies.
Unfortunately, we do not have a micro CT as an industrial company. However, I would like to recommend you to contact Prof. Dr. Numan Durakbasa from Vienna University of Technology, Austria. As far as I know, they have a GE Phoenix 3D micro CT with VGSutdio Max 2.2.
For a sample study, you can check " Measurement Error on the Reconstruction Step in Case of Industrial Computed Tomograph".
I hope they have enough time and personal to help you in your research.
Greetings,
Thanks Ozgur
I appreciate the support. The results will be very interesting. We have a line up of 6 participants so far, we can take up to 12, so more are welcome, especially from industry based CT systems where they have time available. Scan time is max 3 hrs, processing also the same
Happy to get involved: [email protected] - we have also recently run a comparison - see my Contributions.
Thanks Richard, would be great to have you involved. I saw that work and quite nice you also used a 10 mm cube. The difference here is we look more for porosity, but also surface dimensions and topology, so will send you more info
Jaguar Land Rover would also like to participate.
NSI X5000 with 225 and 450kV with interchangeable Flat Panel and Linear Diode Array. VG studio is also available.
Please get in touch [email protected] and i will discuss with my team also.
Thank you for the information, Anton. Looking forward to working with you on this project. Nikon XT H225, Nikon MCT225 + VGStudio MAX.
We would join in with an YXLON Precision CT. VGStudioMAX 3.2 is also available. I'll send you an email as well.
Please have a look at the results of the first round robin test which used identical parts produced from various processes and systems - same analysis procedures used in this current round robin test - paper free to access for next 50 days: https://authors.elsevier.com/a/1XoBM7tcTWTSy5
Hi Anton, is it still possible to participate in the tests? Regards, Elena
Thanks to everyone who contributed and showed interest in this work. The final article is found here, with 50 days free access from today 21/09/2019: https://authors.elsevier.com/a/1ZmZs7tcTWXHTP. Enjoy the paper and thanks for your interest. #additivemanufacturing #microCT
