If only the lottery would cooperate.

If you have a furnace capable of melting aluminum, I can see where 3D patterns for lost wax casting would be sucking you into the vortex. Long long ago, one of my college lab courses let us do some aluminum sand casting. We got to bring in bags of empty beer cans to melt down.

As to printing with extruded metal powder in a polymer binder, then sintering, I'm unfamiliar. Definitely sounds DIY friendlier than laser-fusing metal powder! Sintering anything that requires a reducing or even neutral atmosphere sounds like a major expense... maybe that lottery ticket will help.

Have fun with whatever you do.
