A paper on 3-D printing has been pulled because it “inadvertently” included some sensitive material.
We’re not sure which parts of the paper were the specific problem. But the sensitive material may have something with how to improve the surfaces of 3-D printed products, which is the subject of “Feasibility of using Copper(II)Oxide for additive manufacturing.”
Here’s what the paper, published in the International Journal of Precision Engineering and Manufacturing contains, according to the abstract:
Additive manufacturing, in spite of its ever wider application range, is still plagued by issues ranging from accuracy to surface finish. In this study, to address the latter issue, the feasibility of using Copper(II)Oxide powder with a polymer binder deposited through a Fused Deposition Modeling (FDM) 3D printing technique is explored.
Here’s the retraction note:
The authors have requested this publication be retracted because sensitive ideas, samples and methods used for and described within this publication, developed, produced, and owned by others, were inadvertently included.
We’ve reached out to the corresponding author, Yunho Yang, and last author Kornel Ehmann, both at Northwestern University, and to the editor in chief of the journal, and will update this post with anything else we learn.
