If you take a trip over to tech storage (by engineering, roboticists have access to that room), grab the autolathe, protolathe, and if R&D seems unreliable, destructive analyzer boards.You can temporarily deconstruct a borg recharger and a mech fabber to get the parts needed to construct the protolathe, which you link with your console - then print out several matter bins and another manipulator, with which you can construct an autolathe using the console screen from the mech fabber. Finally, you can print out duplicates of all the parts you've borrowed (and extras, if you want to make other things), and now you've got a fully-stocked fabrication room of your own, without having to wait for R&D to respond to your requests to do things.
