“…Unlike the observation of Liu and Sheen 11 , who concluded that thermal runaway has an input power threshold, it was observed in our previous simulation 14 that thermal runaway occurs when the temperature of the lunar soil exceeds 620–700 °C, regardless of the input power. This temperature is close to the glass transition temperature of the JSC-1A powder (665–695 °C 23 , 24 ). The experimental results presented here found that even the 400 W and 250 W specimens experienced thermal runaway despite their lower peak temperatures and slower temperature increase.…”

For a sustainable human presence on the Moon, it is critical to develop technologies that could utilise the locally available resources (a.k.a. in situ resource utilisation or ISRU) for habitat construction. As the surface soil is one of the most widely available resources at the Moon, we have investigated the viability of microwave heating of a lunar soil simulant (JSC-1A). JSC-1A was thermally treated in a bespoke microwave apparatus using 2.45 GHz frequency, using five different microwave powers in the range of 250 W to 1000 W. The structural properties of the resulting products were analysed to determine whether their microstructures and mechanical strengths differ under different input powers; and whether input power plays a crucial role in triggering thermal runaway, for identifying the optimum power for developing a microwave-heating. Our key findings are: (i) the higher input powers (800 W and 1000 W) generate the highest yields and microstructures with the greatest mechanical strengths, at the shortest fabrication times, and (ii) thermal runaway improves the microwave heating efficiency despite the rapid increase in temperature, once it is triggered. Our findings are of key importance for developing a microwave-heating payload for future lunar ISRU demonstration missions, contributing towards 3D printing-based extra-terrestrial construction processes.

“…Recent work has established that PBF can successfully process naturally occurring terrestrial multi-component ceramic materials of igneous origin, which act to simulate a range of key properties such as bulk chemistry, mineralogy and mechanical performance for indigenous materials found on the Moon and Mars. [10][11][12][13] Previous studies related to the concept of 3D printing using extra-terrestrial/astro-materials as feedstock, and their state-of-the art available simulants, [14][15][16] have covered fundamental topics ranging from raw materials' physical properties [17][18][19][20][21][22][23] and their engineering characteristics [24][25][26][27][28] to the development of process parameters 11,13 for the relevant 3D printing technique. Despite all the work that has been done on the research of the materials and manufacturing mechanisms, there is still little information available on the actual mechanical performance of the fabricated components, especially in terms of relating the resulting material microstructure to the processing characteristics and method.…”

Additive manufacturing and its related techniques have frequently been put forward as a promising candidate for planetary in-situ manufacturing, from building life-sustaining habitats on the Moon to fabricating various replacements parts, aiming to support future extra-terrestrial human activity. This paper investigates the mechanical behaviour of lunar regolith simulant material components, which is a potential future space engineering material, manufactured by a laser-based powder bed fusion additive manufacturing system. The influence of laser energy input during processing was associated with the evolution of component porosity, measured via optical and scanning electron microscopy in combination with gas expansion pycnometry. The compressive strength performance and Vickers microhardness of the components were analysed and related back to the processing history and resultant microstructure of the lunar regolith simulant build material. , with a maximum compressive strength of 4.2 ± 0.1 MPa and elastic modulus of 287.3 ± 6.6 MPa, the former is comparable to a typical masonry clay brick (3.5 MPa). The 2 AM parts also had an average hardness value of 657 ± 14 HV 0.05/15 , better than borosilicate glass (580 HV).This study has shed significant insight into realizing the potential of a laser-based powder bed fusion AM process to deliver functional engineering assets via in-situ and abundant material sources that can be potentially used for future engineering applications in aerospace and astronautics.

“…Basically, lunar regolith is foreseen as a bulk material for key construction activities such as production of concrete-like composites, covering erected habitats and storage structures, filling 3D-printed formworks, and so on. From civil engineering point of view, the full industrial scale production of a lunar concrete-like composite is inevitable (Cesaretti et al, 2014;Grugel, 2012;Pinheiro et al, 2013). Any construction activity is associated with significant volumes of needed materials.…”

A concept of magnetic separation of regolith for production of lunar aggregate is presented in the paper. Future construction effort on the Moon will require significant amounts of concrete-like composites. The authors formulate a hypothesis that magnetic separation of regolith would be a very efficient beneficiation procedure solving multiple civil engineering problems associated with properties of raw lunar soil. For the research program, 10 lunar soil simulants were used. The magnetic separation was feasible in majority of cases. Acquired lunar aggregate would be useful for both concrete-like composite production and covering the surface of a habitat. The aims of future research are pointed out in the paper.
