There are hobby metal printers that may eventually be applicable to regular consumer markets. The reason "open public development" stalled was people were tired of subsidizing cloner companies with engineering projects, and disillusioned by the complete lack of community loyalty to the original authors. i.e. people proved they also didn't want to help pay the original sunk cost just like cloners, and would still get pissy when asking the hapless for support. This is why some have our own metal printers... and the public gets 20 year old glue dispensers on a flimsy CNC platform. Try building your own, it is actually not as hard as people assume. lol =3

Most of the current metal printers have a wacky vendor-specific supply chain, for feedstock and also post-processing. It's not really worth it for me to buy the equipment when I need an ongoing contract for it, and it will severely drop in value / usefulness once the vendor stops supporting it. If I build my own it's probably gonna look like a mig stinger gaffer taped to a second hand kuka ;) I have a CNC taig and a manual mill and lathe. Like most home shops I'm stuck at 90's tech level or below. A lot of innovation has happened in the CNC space since the 90s but not much of it seems to have trickled down :/

  Nice, we've had a CNC taig mini-mill for small <1mm mill stuff around for ages, and linuxCNC is actually surprisingly reliable once setup. Our machines internal CAM release candidate is slowly getting more features, and the slicer part likely will end up FOSS once it meets its goal. You could also check out this great group (kits were around $8k if I recall): https://iro3d.com/ https://iro3d.com/ Or build metal + ceramic composites: https://www.rapidia.com/ https://www.rapidia.com/ YMMV, and remember safety... Ti powders can fail in dramatic ways... =3
