My iron smelter array. Total capacity is 9600 iron ingots/minute, using the basic recipe. I actually only have Mk.4 belts, so I can only use the bottom four (of ten) floors... But I like building oversized. The idea was to centralize the production of basic resources (ingots and concrete). Then, the actual factories making stuff could be located more or less anywhere, regardless of local resources. Centralizing the smelting would reduce the many-to-many distribution problem of resources to a many-to-one (resources to smelter) and a one-to-many (smelter-to-factory). But actually integrating the train station was a pain in the ass and not really fun compared to the factory. I have lots of ideas for how I want factories to look and nowhere can I fit three or more train stations. Maybe this is more a Factorio style and Satisfactory is really more about building the factory close to the resources. So I may not actually end up using this lol. That said, everything is blueprinted now, so I may end up using a smaller version of this design in a different factory. The back, with observation tower for scale.

Shoutouts to the 1.1 vertical nudging feature, which should have been in the game from the start and the new curve mode for conveyors, which look great with the gentle curvature of the main structure.

Dubious shoutout to the feature/bug that vertical splitters now allow you to build X.5m long vertical conveyors, which is a power that I should have used more sparingly.

It's a basic sort of factory system.

Around the map, there are nodes of resources like iron that you can build mining rigs on to extract those resources. Depending on the quality of the node and the tier of the miner, it affects how much ore can be extracted from the node per minute.

Satisfactory also uses a conveyor belt system to transport materials. Like miners, conveyors also have tiers which determine how fast they move and therefore how many resources per minute they can carry. There are also corresponding lifts which are used to transport materials vertically in a compact space.

Conveyors can also run through splitters or mergers, which as the name implies either split materials from one conveyor line into multiple lines to feed into multiple machines, or merge materials from several conveyor lines into a single line such as when consolidating the output product.

Smelters then receive the unprocessed iron ore and convert it to iron ingots, which is a material that is used for a variety of subsequent crafts. The only thing with smelters is that they don't have tiers to work faster; there are ways you can overclock a smelter to produce quicker output, but the resources to do so are finite and expensive.

So, the best way to process more materials at scale is to simply create more of them. And in this situation where OP is extracting an incredibly high volume of iron, they created an incredibly large number of smelters to process it.

Part of the challenge of Satisfactory is how to create elegant systems that are clean and efficient, avoiding tangled messes of conveyor belts, bottlenecks, and deficiencies, so coming up with such a system at a scale like this is very impressive.

Oh my god.

Why not just pure iron?

[โ€“] papalonian@lemmy.world 5 points 1 week ago (1 children)

Yeah, by heart sank a little bit when I zoomed in and saw what was going on, and read the description. Probably one of OP's first playthroughs

Probably more of a Factorio approach

I'd agree with this

How do you use trains in your setup?

[โ€“] papalonian@lemmy.world 5 points 1 week ago (1 children)

For reference, I'm in the aluminum (mid-to-late game) stage right now, on maybe my 5th playthrough with ~800 hours. Definitely people with more experience than me but I've got a pretty good understanding.

The way that I like to do it, for the most part, is to basically do what you did, scaled down, for each resource node/ pocket. For example, when I got to steel production, I found a collection of ~3 iron nodes, made a moderately sized steel production facility, and have that hooked up to my train system feeding two different factories. If I end up needing steel at another factory (or more at an existing factory), I can build a new steel processing plant near another set of iron nodes and be good.

The only "mega processing" plant like yours I've got is for aluminum, which if you haven't got to it yet... Don't worry about it ๐Ÿ˜‰

I also like to try to scale things to use "exactly" the amount of resources from a node. In other words, if I'm making a heavy framework factory, I will dedicate a iron, copper, and oil node(s) specifically to that factory. It makes keeping track of available resources easier (instead of having to remember everything that's hooked up to a source and figuring out how much is left of it, you can generally assume that a node that has been claimed is being maxed out).

Also, VERY important if you are trying to use trains to move the maximum output of your miners/ belts: PUT STORAGE CONTAINERS BEFORE THE INPUT STATION, AND AFTER THE OUTPUT STATION! Unlike in Factorio, train stations stop unloading during the docking sequence, which takes like a full minute. At first it won't seem like an issue, but eventually your input station will back up, the miner will stop, and then your train won't be picking up a full load.

On the input side, you need to use an industrial storage unit (2 ins and outs), use a single belt going in and 2 belts going out; the storage unit will stay empty most of the time, then fill up partially as the train docks, then use both belts to empty the surplus into the station when it's done. Do the opposite for the output (2 belts in, 1 out). I spent hours trying to figure out why my stations weren't running at 100% until I saw this is what was happening...

Sorry for the huge wall of text! I love this game and don't have any friends that play to talk to about it. Lol.

Interesting writeup.

The tracking of how much of a resource node goes where was supposed to be removed by everything going to the big smeltery, so I only need to track how much is going in and out of the central smelter.

I noticed the locking thing when turning on the factory. Unfortunately this would mean that there is way to get two full belts of output out a train stop all the time. If the downstream machines always consume two full belts, there is never a chance for the container to fill up. That sucks.

Trains are very cool in any game that they are in, but their infrastructure, especially the stations, is so huge and unwieldy in this game, that I will rethink organizing my factory around them, especially since there does not seem to be a huge need to move large quantities of items over long distances. I could see them on a point-to-point basis when a particular set of resources isn't close to each other.

Also Re: Aluminium: I've seen the recipes, seems like a good time. I've played Gregtech, so I'm used to worse.

[โ€“] papalonian@lemmy.world 2 points 1 week ago

This will change as you get later in the game. For example, you need quartz and bauxite for aluminum processing; there aren't many pure nodes of either close to each other, so unless you want to set up an aluminum factory multiple times, it's better to train them into a central location.

The recipes aren't so much the issue with aluminum, as is building your machines in a way such that everything flows nicely is.

I agree that trains in this game are very unwieldy. In Factorio, my favorite station design was having a rail branch up/down two rail blocks, train station, then back into the main rail. Quick, easy, very compact. No such structure in satisfactory; 5 foundations wide just to branch off the main rail, plus 2.5 more to accommodate the width of the station..

I considered it. There is no shortage of iron ore on the map, it would just mean a few more trains coming in. By the time this thing would be at capacity, I would have Mk.3 Miners and then 9600 ore is just 8 pure nodes, fully overclocked.

I didn't check the difference in power consumption, maybe that would be enough to tip the scale. Mainly I didn't want to deal with head lift in such a vertical build.

Maybe I should note that to me, more machines and more machines are not downsides, but upsides. I like lots of trains and I like huge Arrays of machines :)

Dear god in heaven. I can feel the heat from your PC from here.

[โ€“] Scaatis@feddit.org 3 points 1 week ago (1 children)

You know the factory is good when it tanks your framerate.

[โ€“] Ziglin@lemmy.world 1 points 1 week ago (1 children)

Yeahโ€ฆ That's the reason I've pretty much given up on my >105 nuclear power plant setup for the end game. (The power plants alone would need over 24k cubic metres of water per minute btw)

[โ€“] Scaatis@feddit.org 1 points 1 week ago (1 children)

That sucks. Is it tanking the framerate only when you look at it or all the time?

You can try lowering all settings to potato and use photo mode for the money shots, it will render at a higher quality.

[โ€“] Ziglin@lemmy.world 2 points 1 week ago (1 children)

Yeah, I played a little more today. It lags most when switching floors. (Which I need to do a lot to get >24k Water to the right floor.) Turning down the settings helped a lot though (not quite sure why they were so high), I'm back up to 35-40fps there now. (And 60fps most other places)

[โ€“] Scaatis@feddit.org 1 points 1 week ago

Great to hear!

Build that vastly oversized monster factory!

[โ€“] Zdvarko@lemmy.world 2 points 1 week ago

Impressive, agree the vertical and infinite nudge is exactly what was needed. Looking forward to the stable release of 1.1 so I can use mods like perma day
