In addition, while this isn't 1/1 scale, it's 1/3 scale, it's not like these are tiny miniatures on a desktop, and you will recall that the gravity in which these structures are assembled is roughly 30% that of Earth's, with almost nonexistent wind and weak geological activity if any. At it's current thickness here on Earth that basalt polymer buttplug could have stood to it's full size on Mars, and while it was about an inch thick in the test I think they said they would want it to be 3" on Mars, so not only could it be to the full proposed sized, but two or three times upscaled beyond that, or close to the size of a nine story building.
Both of these structures were also subjected to a weight test in which a fifty ton excavator lent it's weight on top of them. Both did crack eventually, however the cuckcrete hut was crushed into powder immediately, while the basalt polymer structure held the entire fifty ton mass of the excavator for several seconds before only a part of it cracked off.
The cuckcrete extruder also suffered a serious malfunction, liquid concrete hardened in the pipe and required human intervention to pick the shit out of there. The basalt plastic one suffered a print programming issue which had it printing too fast and thus overheating some layers near the top, however this problem could be mitigated by a fine tuning of software.
In that particular test the basalt polymer PROOOONTER won not just because it was shique and new, but because the competing process proved in practice to be strictly inferior.
