Caprio et al. reported maximum compressive strength of 31.4 MPa for L-PBF of NU-LHT-2M highlands regolith simulant.
“They reported a maximum compressive strength of 31 . 4 MPa , well above the properties achieved through alternative methods.”
From A comprehensive review of lunar-based manufacturing and construction (2024) · cites this paper as [129]
Section 3.3 (page not specified) reports a highest compressive yield stress of 31.4 MPa for LPBF-processed NU-LHT-2M, supporting the reported value. Its comparison with alternative methods is more qualified: some methods produced lower values, but thermal sintering exceeded 200 MPa, so the result was not generally well above alternative methods. (LLM, conf=0.90)
Experimental — accuracy not yet measuredThe study by Caprio et al. did not assess how atmospheric and gravitational conditions affect the properties and qualities of the print.
“Additionally, the study did not assess how these conditions affect the properties and qualities of the print; a more thorough evaluation is necessary.”
From A comprehensive review of lunar-based manufacturing and construction (2024) · cites this paper as [129]
Caprio et al.'s findings on atmospheric and gravitational conditions are purely theoretical and lack experimental validation.
“However, these findings are purely theoretical and lack experimental validation at this point.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
