This is easy, all you have to do is go to the entrance of your ship inside or outside.
Then queue up a full stack of crafting items on your companion which are the same type, then let them go and create them.
As the first item is complete quickly enter your ship, then re-queue the maximum of 5 again with the same crafting items and click the Ship Exit.
All the items should now be created instantly and be in your inventory. This takes a few tries to perfect but is worth doing if you want quick items and skill up.
So basicly-
1) You queue 5 of the same item for crafting.
2) You wait until the first item finishes.
3) You quickly enter your ship.
4) You again exit your ship.
5) 3 Items will be completed, 2 in queue.
6) Cancel the rest of them, Queue 5 more and repeat.
