This is an extensive general guide on gathering and collecting materials for engineering your ship in Elite Dangerous. For a more focused list of material sources, check out Elite Materials.
You DO NOT have to max out the previous grade of an engineering blueprint before applying the next. A module only stores one grade of engineering, so each higher grade replaces previous ones.

Raw materials (Grade 4) can be easily obtained en masse at special Crystalline Shard Biological Sites. A large cluster of these sites, consisting of purely the highest grade (G4) of Raw materials can be found at two systems approximately 1500-1800Ly from the bubble. We recommend putting together a decent exploration ship (unengineered works) and visiting both systems to completely fill on all G4 materials (except Selenium) which you can trade down for any lower grade materials you may need. This should last you for multiple full ship engineering builds.
Selenium has no known crystal shard sites. However, Odyssey introduced new sites which can be farmed at nearly the same efficieny. (see below)
To use these sites, you will need to go to the celestial body corresponding to the material you require and use your Detailed Surface Scanner (DSS) on it. When this is done, select Crystal Shards and look for dark blue areas. Fly down to the planet and look for shards on the surface. Land, and hop in your SRV. You should be able to find plenty of rare raw materials for all your engineering and synthesis needs.
Do not forget to bring a Detailed Surface Scanner and SRV
Dumbfire missiles can be used to increase farming efficiency, as demonstrated here.
Selenium is (ironically) the most difficult material to farm since it only drops from Grade 2 resource nodes. There are multiple ways to collect it however, albeit slightly slower. The best way is brain trees, which can be farmed similar to crystal shards. Brain trees for selenium can be found at Kappa-1 Volantis, B 3 F A
Thargoid Barnacles can provide a good source of selenoum as well, as breaking the spikes most commonly drops G1-G2 materials, but locating the correct barnacle may be tricky. You can use this spreadsheet compiled by CMDR Panpiper to find the correct sites. Look for Allripe Barnacles with Selenium present on the planet. Additionally relogging will cause the spikes to reappear, which means you can repeatedly farm the same site.

HGE Looping is a time-efficient method of grinding Grade 5 Manufactured materials. Ideally you will want to be using a ship with at least 3 collector limpets and a good turn rate in supercruise.
The contents of a given HGE are determined by system allegiance (Federation/Empire) and minor faction state (Outbreak, War, etc.) and spawn at random in systems in such states. See Elite Materials for more information on what material corresponds to each faction state.
You can use the min-ed-launcher’s auto-restart feature to save some time on each game restart.
If you have a weak PC (or want to speed up the grind even more) you can load the vanilla (non-horizon) version of the game, as it loads faster.
While HGEs are the fastest way to farm most manufactured materials, some CMDRs prefer other methods, such as Hot Jupiter, Big Boo, or Dav’s Hope.
Additionally, Biotech Conductors and Exquisite Focus Crystals cannot be obtained from HGEs, and are instead obtained from missions. Robigo Mines or Thargoid-related missions are currently the best known ways of obtaining these materials
You can find a collection of high grade encoded materials by travelling to Jameson’s crashed cobra and scanning the small red beacons surrounding the crash site, once you log out/in these will refresh and you can continue to do this until your materials are full.
Guardian blueprint fragments come in three forms: Weapon, Module, and Vessel. Each active guardian site will provide one of these types. While many CMDRs have sites they prefer to use, we recommend HD 63154 planet B 3 A for modules and Col 173 Sector OD-J B25-2 planet B 1 for weapons.
Guardian materials can be found at various active guardian sites. Some drop from destructible panels, and some drop from destroyed sentinels. A list of where to find each material can be found here.
Guardian Pattern Data comes in various forms, and can be obtained from scanning any active obelisk. Drops are random, and many relogs are required to get the data you need. While any guardian site has active obelisks, we recommend Synuefe XR-H D11-102 planet 1 B for pattern data, as there is a site with 4 obelisks next to each other.
Canonn Research group has multiple repositories of guardian site maps, some of which can be found here and here.
Required to unlock the Engineer Professor Palin, sensor fragments can be gathered from Thargoid Scavengers or by destroying Thargoid Sensors. You can find Thargoid Sensor fragments very close to Professor Palins lab at a recently discovered crashed ship at the following location.
System: Solati
Body: Halla
Coordinates: -70.9912 x -156.4383
Stuff: 1 Thargoid Sensor, 1 Cargo Rack which drops one of the following (V, Cr, Zr, Zn, Mn, Sb), Ship Data Core.
This is the closest system to Arque (Palin) to get Sensor Fragments at less than 28 LYs distance. Destroy the Sensor to gather the fragments. You can relog at this site to spawn another.

If you are not able to obtain the materials you need directly, it is possible to trade other materials of the same type at a material trader for a cost. Different material traders will handle different material types such as Data, Raw and Manufactured.
You can find the nearest trader with Inara’s station search.
When trading you will always lose some value. You will lose even more if you trade across different categories.
Ideally you want to gather materials at the highest grade possible and trade downwards.
