It just marks the chair, fuel port, tech station, and storage locker as moveable, it doesn't allow you to make them. Though I haven't much use for the ship without all of my loot in it, and this character is barely used, so I'm probably just going to abandon it.
The maker of the mod I use informed me that all the vital ship bits including the thrusters can be scanned and printed for 1 px per by default. You... kinda can't print off another tech station though so there is that.
To get a new set of the default parts:
1) Go to the player folder in the main starbound folder. There should be sets of 3 files: (long alphanumeric string).metadata, .player, and .shipworld. The .shipworld is the one you want.
2) Open .shipworld file or .player file in notepad. Somewhere on the first line should be the character's name. Note which alphanumeric string corresponds to your character.
3) Change the extension on the appropriate .shipworld file to .shipworld_bak
4) Start the game and load the character. Missing a ship will cause the game to generate a new default .shipworld file. Grab the important bits.
5) Delete the character's .shipworld file, and rename the backup to .shipworld.
You should now have your old ship back, with the bits from the fresh ship still in your character's inventory.
