3D printing in aerospace and its long-term sustainability
Open accessAbstract
Astonishingly 3D printing has excited the world of aerospace. This paper takes stock of the popular 3D printing processes in aerospace. Reasons for their popularity over the traditional manufacturing processes are dwelled upon. Materials developed specially for aerospace applications along with their characteristics are discussed. Ongoing activities related to 3D printing at various companies and organisations around the world are looked into. Project works in the area of extra-terrestrial printing are also highlighted. Even though 3D printing processes are operationally simple, they do have limitations in terms of the type, quality, and quantity of the materials they can handle. This paper underlines these points while discussing drawbacks of the printed components. Challenges associated with 3D printing in microgravity are also touched upon. Finally, a glimpse is taken into the future appearance of aerospace industry with 3D printing.

AM produces little to no waste with buy-to-fly ratios of between 1:1 and 3:1.
“By the nature of the layer-by-layer manufacturing process, AM produces little to no waste with buy-to-fly ratios of between 1:1 and 3:1 [18,19].”
From Metal additive manufacturing in aerospace: A review (2021) · cites this paper as [19]
The Material Wastage section says AM involves little to no raw-material wastage. The General Outlook section says 3D printing can reduce the buy-to-fly ratio to almost 1:1, but it does not give the claimed upper bound of 3:1. Page numbers are unavailable in our copy. (LLM, conf=0.88)

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.
