Modulus Academy | Episode 7: Expert Production Layouts

David's back with what might be the most mind-expanding episode of the Academy yet. Episode 7 is all about expert-level module production, a fundamentally different way of thinking about how you build. If you've ever felt like your factories are getting the job done but taking up way more space than they should, this one is for you. If you’ve ever seen one of Jarvs’ streams then you know what we’re talking about (hehehe).

The core principle underpins everything in this episode: the more voxels you can manipulate in one operator, the fewer operators you need.

The Standard Approach | Efficient, But Spacious

David starts by showing how most players tackle module production, using a module for the Lumite Reactor as his example. The typical approach: take a full belt of cubes, assemble to a big block, cut it into the smaller pieces that make up the module, paint and stamp the individual parts, then reassemble them.

It works. It's completely efficient, 240 cubes per minute in, 240 modules per minute out. But it requires repeating the same sequence of operations four times across a lot of operators and a lot of floor space. It gets the job done, but there's a much smarter way to think about it.

Think Before You Slice

Rather than immediately cutting your big block into individual module-sized pieces and processing each one separately, David introduces what he calls the sushi roll approach.

The idea: instead of thinking about one module at a time, think about how you could arrange multiple modules together within the big block before you start cutting. If you glue the modules next to each other, and crucially, rotate some of them, you can arrange them so their matching parts line up across the whole block. That means you can stamp, paint, or cut across the entire block in one operation rather than repeating the same operation on each individual piece.

In David's example, by rotating the modules within the block so the black parts align, he reduces the number of stamping operations needed from many down to just five, producing something he describes as a mould that the other pieces slot neatly into. One final cut at the end slices the whole block into four finished modules at once.

The result: 60 big blocks per minute in, 240 modules per minute out, and dramatically less space required to get there.

Assembling Floating Parts | You Don't Have to Join Everything Up Front

The second technique David covers is what he calls assembling floating parts, and it's a subtle but powerful shift in thinking.

In a standard setup, you might feel like you need to attach each individual piece to the main block as you go. But Modulus doesn't require that. You can combine parts together that aren't yet attached to anything, building up a floating sub-assembly, and then attach the whole thing in one go later in the production line.

In practice this means instead of using a monotoner on four separate black pieces individually, you can assemble those pieces into one floating cluster first and monotone the whole thing in a single operation. Four steps become one. Applied across a full production line, the savings stack up fast.

Putting It Together

Combining both techniques, David's optimised setup produces the same 240 modules per minute as the standard approach, but in a fraction of the space. He also uses four times less paint in the process, since painting one large piece covers what would otherwise require four separate painting operations.

Once it's working, David's habit is to clean it up into a tidy, blueprint-friendly rectangle, easy to copy, easy to place, and satisfying to look at.

The takeaway: before you start building, spend time looking at your target module and asking two questions. Which parts can be combined into a bigger volume before processing? And can rotating the arrangement reduce the number of operations needed? The answers will make your factories smaller, cleaner, and a lot more satisfying to build.

That's Episode 7! If this one made your brain hurt in a good way, drop your questions in the comments, and make sure you're following us on Steam so you don't miss the next episode.

See you on the factory floor.
