Fused Layer Deposition of Lunar Regolith

In order to enable lunar exploration in a sustainable manner, it is necessary to develop technologies that allow the use of lunar resources in-situ. Additive manufacturing techniques are being studied for in-situ resources utilization on the Moon (e.g.: solar or laser sintering). The results of these studies, presented samples with low mechanical properties due to the formation of defects and cracks within the final product.

Moon Fibres

Institut für Textiltechnik der RWTH Aachen University (ITA) and Institute for Structural Mechanics and Lightweight Design RWTH Aachen University (SLA) have already spun MoonFibres from regolith simulant. Gradel SARL uses the xFKin3D technological process to produces ultra-lightweight structural components made of various types of fibres and resin. This technology requires less material to create parts with equal structural strength as the ones produced in traditional ways. The produced parts can be 2D or 3D parts.

Robotic manufacturing of fibrous structures in space

Motivation: This study aimed to develop promising robotic fabrication methodologies for a fibre-based in-situ robotic fabrication process, for application in a lunar habitat as an alternative to existing additive manufacturing methodologies. Previous work has verified that fibre composite fabrication processes are capable of a high degree of automation and structural performance.

Lunar ISRU demonstration mission definition study segment 1

The contract was part of the broader framework of two ESA-led mission study teams performing parallel and independent activities to establish the mission concept, considering the ISRU payload (Segment 1), the delivery service (lander, Segment 2) and the communication service (Segment 3).

In this context the scope of the OHB Italia contract activities was related to defining the ISRU Payload.

Lunar ISRU Demonstration Mission Definition Study Segment 2

The main aspect of this study is to investigate the feasibility of the mission concept and the demonstration of the economic viability of a commercial payload delivery service to the Moon, as well as demonstrating the production of water/or oxygen with materials from the Moon. The study considered a payload delivery service that would be an end-to end service from Earth to a targeted location on the Moon, launched not later than 2025.

Conceiving a lunar base using 3D printing technologies.

Several studies have addressed the building of a lunar base either under ESA or other space agencies and entities. These studies have looked at conceptual designs, often of one specific element of the base, while most of the requirements are not adequately or not at all taken into consideration.
