The Super Extractor is currently the best Extractor in the game. It gives the player thrice as much Ore and takes a third of the time of the Extractor. It can be built in your Crafting Menu (default key "Q") or at any Crafting Table in worlds created before R22 on September 16th 2015 with 4 Stone Rods and 4 Obsidian Rods. To craft Super Extractors you need to first learn the Recipe which is dropped or pet-harvested from the Thing, found in the Corruption layer.
