Ion makes a good point and I really like the idea of building any spare parts by just going to a catalog and choosing the part needed. It also makes sense to build it now as needed and pay on return to a starport.
To get around this how about a 3D Laser Scanner. You put the object inside scan it and sent it to the 3D printer or store it on your computer.
Jeff also made a good point about how good is the part the printer makes, will it hold up good as new or will it break, shatter or fail in a short while??
Say your jump drive takes a hit and you build a spare 3D part. Here I think the wear value will be effected say roll 1D6-1 and subtract the number from the J-Drive's current wear value. When the wear value number is failed the part is destroyed/ broken and if it breaks catastrophically several parts may need replacing. For the materials that can be used in printing I would look at the FF+S materials construction list and subtract at least two tech levels: Aubaine could print using Crystaliron.
Here is a real world 3D printer that I could see on a Far Trader sixed ship:
2.8x1.8x1.8 meters volume 1950 kg Cr 150,000
Tray size 1x 0.8x0.5 meters
uses 18 kg cartridges Cr 180
Materials that can be used in #d printers:Rubber, Plastics, Paper, Polyurethane, and metals.
Smaller desk top 3D printers have 21x21x20 cm trays Cr 580, Weight 25 kg (app) and use 1kg spools of PLA plastic Cr10/ spool.
Check out the KamerMaker 3D printer with a table area of 2x2x3.5 meters. It seems to be a demo printer to see just how big can they go The two small ones I can see as part of s starships machine shop, but the biggest one only at a starport's repair or construction docks building component parts like J-Drive hull casings.
Still, its interesting tech
