  Security of Additive Manufacturing (AM) gets increased attention due to the
growing proliferation and adoption of AM in a variety of applications and
business models. However, there is a significant disconnect between AM
community focused on manufacturing and AM Security community focused on
securing this highly computerized manufacturing technology. To bridge this gap,
we surveyed the America Makes AM community, asking in total eleven AM
security-related questions aiming to discover the existing concerns, posture,
and expectations. The first set of questions aimed to discover how many of
these organizations use AM, outsource AM, or provide AM as a service. Then we
asked about biggest security concerns as well as about assessment of who the
potential adversaries might be and their motivation for attack. We then
proceeded with questions on any experienced security incidents, if any security
risk assessment was conducted, and if the participants' organizations were
partnering with external experts to secure AM. Lastly, we asked whether
security measures are implemented at all and, if yes, whether they fall under
the general cyber-security category. Out of 69 participants affiliated with
commercial industry, agencies, and academia, 53 have completed the entire
survey. This paper presents the results of this survey, as well as provides our
assessment of the AM Security posture. The answers are a mixture of what we
could label as expected, "shocking but not surprising," and completely
unexpected. Assuming that the provided answers are somewhat representative to
the current state of the AM industry, we conclude that the industry is not
ready to prevent or detect AM-specific attacks that have been demonstrated in
the research literature.
