Having recently purchased ~400 dental surgical instruments from some dude in Pakistan for less than $2000 including shipping, and received them in less than a month even though they were manufactured after I ordered them, I can imagine no possible purpose of 3D printing surgical instruments. They are stainless steel and will last approximately forever.

Might want to look up the IFU or AORN standards for those. I know many places either toss them out of their kits or are single use only. Something about pitting and the metal they are made of.
