Jaime Bonnín Roca is co-author of the article “Policy needed for additive
manufacturing, published” in the August edition 2016 issue of Nature Materials,
as a result of his part A Qualifier Examination. The exam is part of the
mandatory evaluation procedures of the Engineering and Public Policy (EPP) PhD which
the student is attending at Carnegie Mellon University (CMU) and at Instituto
Superior Técnico/Universidade de Lisboa (IST/UL). The student had also achieved
the Best Part B Qualifier Examination, with a case-study in autonomous vehicles
public policy analysis.

believes that the article was well received by the high impact factor journal
because “many articles talk about additive manufacturing's advantages and potential,
but few about the limitations”. The author thinks that “it probably was a
needed counterpoint, given the rising interest in the technology. Moreover, regulation
of new technologies is always a controversial topic and we offer some
constructive insights trying to balance the interests from both industry and
Also asked about the
secret for such a well succeeded examination, Jaime justifies the great results
with calm and knowledge.
“The secret was
keeping myself calm, and trusting the education I had received at Carnegie
Mellon. Some of my (very bright) colleagues panicked and that obviously had a
negative influence on their answers. Being in Portugal, away from Pittsburgh's
atmosphere where peer pressure iscontagious, probably
The article states
that “the successful adoption of metallic additive manufacturing in aviation
will require investment in basic scientific understanding of the process,
defining of standards and adaptive regulation”.
About achieving the
Best Part B Jaime Bonnín Roca
says, “It was fun, but I didn’t
expect to win. Autonomous vehicles are all over the news but there are still
challenges. I think my solution stands out in analysing social implications of
The part B exam is an extended take-home examination
on an applied problem in policy analysis.
As CMU clarifies, “the Qualifying Examinations
are conducted once a year, in January”, and part B is always after part A. The
exam “must be taken after students have been in the program for three semesters.
The objective is to assess the student's ability to do interdisciplinary
“I was confident I would pass Part A. After three
semesters, there should not be room for surprises regarding research. Part B is
trickier because you never know what to expect, and you may simply have a bad
week. However, it is also fairer because all the students have the same problem
to solve”, explains Jaime Bonnín
Jaime Bonnín Roca works on the feasibility and
impact of additive manufacturing in the aerospace industry and his provisional
thesis title is “Challenges and Opportunities in the Introduction of Metal
Additive Manufacturing”. His advisors are Joana Mendonça (IST/UL) and Granger
Morgan, Erica Fuchs and Parth Vaishnav (CMU) and his expected conclusion date
is Spring 2018.
is also linked to CMU Portugal Entrepreneurial Research Initiative E4Value. The
main objective of this project is to understand how a country such as Portugal
can be more effective and proactive on the aeronautics industry.
