Home 3D metal printing: first results
Important note here - this is not equivalent to the typical powder metal sintering printers that people are probably thinking of based on the title, which are still in the $100K+ range.  This is an example of normal FDM printing with metal-infused filament and then fusing the layers in a furnace, which is quite a bit easier to accomplish, but also messier and more time consuming.A few people are working on metal powder sintering at lower price points, but I haven't seen any massive progress in that space lately.
