Utilizing in-situ resources and 3D printing structures for a manned Mars mission

• Presents Martian mission concept that utilizes in-situ resources for 3D printing of base structures.
• Considers logistics of basalt 3D printing and maintaining a pressurized environment in printed structure.
• Evaluates proposed approach by comparison to prior missions׳ mass requirements.

This paper presents a manned Mars mission, which is based on the use of in-situ resources for the fabrication of structures. First, it provides an overview of the two-phase mission. In phase one, robotic construction units prepare a functional base for phase-two human habitation. Then, it describes a set of prospective structures that can be created utilizing additive manufacturing (commonly known as 3D printing) techniques and in situ materials. Next, the technological advancements required to allow this type of mission are considered and their feasibility is discussed. Specific focus is given to the topics of basalt 3D printing and the maintenance of the pressure environment. The process of the construction of the base is also discussed. Finally the proposed approach is analyzed through comparison to prior missions, before concluding.
