Engineering materials: easy peasy

Personally I was tired to look at youtube videos to look for systems where to farm materials so I compiled a list for quick access for myself. I hope it can be useful for you as well.

You need to this to find the systems you need and the re-log method for the Manufactured and Encoded…and if you go to Koli Discii for the raw materials.
Note: use a medium or small ship if you want to self destroy and save the trip back, but also because some locations are a pain to land with a big ship.

Just to be crystal clear: this is not my work, but I took the information from Hawkes Gaming. I like his videos, although sometimes he pisses me off that he doesn't put the key info in the description.
