I'm not sure there is a lost wax printer, but people do "lost pla" casting. I was experimenting with headbadges that way. I'm not sure a lug would pass the design tests.
ETA: it's expensive, but you can just direct print a lug. People are doing it with Ti, but it costs a ton. I don't think that steel would be much cheaper
