Kevin,
What kind of printer are you using, the powder printers are not getting very smooth, but depending on base material strength varies.
There is also.metal printing which several classic car suppliers to oem market are using the remanufacture obsolete cast parts
I use MakerGear M2 printers, and they are one of the best on the market for PLA, ABS, and Nylon printing. They use filament but produce a very nice product.
Metal printers are horrendously expensive and way out of my market, but yes, that is an alternative.
