Secure Additive Manufacturing Process Chain

The increasing use of Additive Manufacturing (AM) technologies, colloquially known as 3D printing,
in Industry 4.0 and Manufacturing-as-a-Service has made it a topic of interest for IT security and
forensics. Especially the use of AM for safety-critical parts, for example, in the SpaceX SuperDraco
engine or parts of an Airbus jet engine, underlines the importance of such research.
Additive manufacturing follows the CAD/CAM/CNC process chain. In the Computer Aided Design
(CAD) step a volumetric model of the part is designed. Based on the machine and how the part is
to be produced the model is next converted to machine instructions in the Computer Aided Manu-
facturing (CAM) step. Finally the instructions are performed by an Computerized Numerical Control

Securing the CAD/CAM/CNC process chain (see figure) thus requires a holistic security approach
to secure digital data against malicious manipulations along the whole process chain. The goal of
the thesis is to evaluate existing approaches to secure additive manufacturing and similar process
chains. Based on the findings, a security concept shall be developed which ensures authenticity
along the process chain. This is then prototypically implemented on a 3D-printer. The prototype
could be done by adding plugins or extensions to slicers and printer firmware.

• Self-initiative an the ability to work self-directed and systematically
• Knowledge in the field of IT security, ideally already in OT Security
• Experience in programming and software development
• Interest in additive manufacturing and 3D printing
