what you can do is to use a filament with aluminium as the colourant.

My personal favourite is reprapper techs pla with aliminium. Has a great silver metallic finish that could be shined up with a quick coat of varnish.

So, yes, technically all those parts could be easily replicated on an fdm machine.
You might want to sand the print marks out, but that would onl;y be for stuff on the exterior. Interior parts could be used as they come off the printer.

Have a look at openscad.
That and a set of digital calipers and you can replicate just about anything :-)F

for the clear window - buy some thin perspex and cut it to size and glue.
