What are you classifying as ‘affordable’?
below 10,000-15,000 dollars? the cartridge should be affordable as well so not more than 100$ per killogram
There aren’t really even sls printers in that price point yet despite there being somewhat cheaper ($20kish) options for awhile. I wouldn’t expect anything for at least 5-10 years.
Depending on your use case, some high performance polymers like PEEK or Ultem (PEI) can have many advantages that metals have, but are still considered plastic, so you can print them relatively normally with SLS or sometimes even FDM printers.
Printing metals is often way harder than polymers, due to high temperatures needed, and post processing is also way harder.
What are your needs?
