We like our Saturn. It's the printer that produced the PRR flat car I posted earlier. I just received the MARS 3 which has better XY resolution (0.035 mm) to use to print small parts. Still need to clear the space for it and its wash/cure stations.
Yo might try using your FDM to print the railings. Using the filament by itself would makes a 3.3" railing.
