Energy-efficient regolith compactor for surface construction

The objective of the project was to design, develop and test the compaction device breadboard in a regolith simulant testbed. An experimental test campaign aimed to verify that the compaction device can be successfully used to improve the surface geotechnical properties of two different regolith simulants: GreenSpar-250 analogous to lunar Highlands, and AGK-2010 analogous to lunar Mare regions.

LUPIN (Lunar Lithography Manufacturing)

Nowadays, human Moon exploration, and the consequent desire to establish a permanent settlement on its surface, represents one of the most fascinating challenge to face. The permanent presence of a human outpost very far from Earth raises the problem of the huge amount of payload required for the settlement, as well as the need of rapid and in-time supply of material and spare parts useful for all the activities carried out in-situ, including the realization of medicals tools and patient-specific back-up implants.

Basalt fibre reinforced geopolymer made from lunar regolith simulant

The objective of the study was to investigate the performance and shielding abilities of lunar regolith-based geopolymer when reinforced with basalt fibres and cured under environmental conditions of the lunar surface. The geopolymer building materials should be suitable for
3D-printing on the Moon. Since there is a very limited supply of water on the moon, the study also focuses on lunar geopolymers with a reduced amount of water in the recipes, without the need for raw materials that cannot be resourced locally on the Moon.

Additive manufacturing of functionally graded ceramics with in-situ resources

In this activity, lunar regolith simulants were characterised based on their thermal behaviour, particle size distribution and composition, in order to inform the choice of consolidation method for functionally graded materials (FGMs) – powder characterisation results are provided in the 'conference paper' deliverable.

Firstly, an extensive literature review study (deliverable 'Literature Review') identified Digital Light Processing (DLP) and Spark Plasma Sintering (SPS) as promising consolidation techniques.
