So far I've only printed some parts for reel support on the printer, a couple of toys for the kids, a Tie fighter and a 15 mm Tiger tank.
All these things were printed in PLA. Because of the size of my printer I am limited to smaller things, since assembling multi part kits is still a bit scary.
All things considered I am fairly happy with the reults, but we are not yet at miniature quality. Printing components is feasible (shield bosses and such), but so far it's far more work to get the files ready and print + glue them than it is to simply mold them. I'll be experimenting further, but if you consider getting into this game, I fear my cheapo entry level printer just won't do. Which is what I expected really...
That said, it is very much fun to do, and with a few lessons I am sure I'll get the hang of it.... eventually.
