Gotcha, yeah unfortunately FDM ceramic still has crazy high spool costs so I don't think it really puts it into the same ballpark as using simpler materials. We're talking like $500 a spool, just one printed piece like you see in the picture looks like it would take an entire spool or more and could be the better part of $1K. I'm comparing to Mossy Earth's strategy of binding together metal rods and coating with sand, which after labor lands at $26 per structure.
