@ Above because he only wanted to have induction furnace that being an actual RL technology
This makes no sense! IRL we have those kinds of machines in different capabilities. Cheaper, more common machines like official IC² and more expensive, high tech, high output machines like the induction furnace or these from the addon!
Besides in IC² we have the mass fabricator that itself and the use in the mod is completely unrealistic, but it's there and people love it, even more considering it's a good excuse to develop nuclear reactors that are more crazy then Chernobyl's.
It makes perfect sense to have an advanced counter part to the standard machines!
