Heh, was just about to post something related...
What you really need is a mat' scavving ship.
An AspX does the job pretty well:
https://s.orbis.zone/3265
Detailed Surface Scanner for locating raw mat's on a planet surface.
SRV for collecting raw mat's and encoded mat's.
Collector Controller for collecting manufactured mat's.
Cargo rack for holding limpets.
Shield in case you bump into anything (you won't be getting shot at).
Fuel Scoop in case you need to refuel.
Wake Scanner for collecting encoded mat's.
With a ship like that you can collect every mat' you'll ever need.
Course, you can fit roughly the same stuff to
any ship but the AspX has other, erm, benefits that will become apparent as you become more knowledgeable.
