The new sintering processes and alloys have gotten amazingly close for most purposes to be indistinguishable in application. Like any additive process, it still often requires machine work where precision is important.

Tht said... I am sad to see that lately, casting being overlooked often when it is still the best choice in many projects just because '3d printed' sounds better in the marketing. I have in front of me a 1960s magnesium alloy casting from the early 60s and the quality would make most sinterig operaters beyond jealous. Not to mention the material properties.
