PhD Position: Additive Manufacturing and Composite 3D Printing for Lunar and Earth Applications

Are you passionate about advancing additive manufacturing for both space and terrestrial applications? The Technical University of Denmark (DTU) invites applications for a fully funded PhD position in the Digital Building Technologies section of the Department of Civil and Mechanical Engineering. This research opportunity centers on developing a novel 3D printing system for melting and extruding lunar regolith, alongside pioneering composite 3D printing through experimental testing and process development. As a PhD student, you will engage in hands-on experimentation, advanced digital fabrication, numerical modelling, material testing, and process optimization. Your work will include fabricating and mechanically characterizing composite specimens with tailored fiber orientations, exploring how printing strategies influence thermo-mechanical properties. You will also contribute to the design, integration, and operationalization of a molten regolith extrusion 3D printing system, supporting autonomous, in-situ resource–based construction for lunar environments. DTU's research group is dedicated to the digital transformation of the built environment, leveraging technologies such as additive manufacturing, artificial intelligence, automation and robotics, digital twins, and smart materials. The project objectives include advancing continuous fiber-reinforced additive manufacturing, optimizing composite 3D printing processes, and developing hardware and control systems for lunar regolith extrusion. You will collaborate with experts in materials science, mechanics, and digital fabrication, gaining exposure to cutting-edge developments in 3D printing and robotic systems. Applicants should possess a two-year master's degree (120 ECTS points) or equivalent, with a strong background in additive manufacturing, composite materials, or robotic fabrication. Experience with digital design and control tools (MATLAB, Python, ROS), robotic systems (ABB, KUKA, UR), machine development, material testing, and process optimization is highly valued. Additional advantages include knowledge of fiber-reinforced polymers, large-scale 3D printing systems, space-related applications, and simulation tools (COMSOL, ANSYS, OpenFOAM). The position offers a 3-year employment period, with salary and terms based on the collective agreement with the Danish Confederation of Professional Associations. DTU provides a dynamic, international research environment, with support for relocation and integration into Denmark. Monthly seminars are available for incoming PhD students to address practical matters related to moving and working at DTU. To apply, submit your complete online application by 22 December 2025, including a cover letter, CV, and academic diplomas in English as a single PDF file.
