How to Make Fused Modular Frame in Satisfactory

Updated 21 Oct 2026 Source Satisfactory in-game mechanics and community documentation, retrieved 21 October 2026 By

Fused modular frames are a heavy late-game part used in the space elevator and advanced builds.

What you need

  • Heavy modular frames.
  • Aluminum parts or other advanced inputs.
  • Manufacturers to combine them.

Step-by-step build

  1. Produce heavy modular frames and the required advanced inputs.
  2. Feed all inputs into manufacturers to make fused frames.
  3. Belt the fused frames to storage or the space elevator.
  4. Balance all inputs to the manufacturer.
  5. Add manufacturers as demand grows.
  6. Overclock the lines that fall behind.

Throughput tips

  • Keep heavy frames and advanced inputs balanced
  • Belt frames to storage
  • Add manufacturers to scale
  • Feed the space elevator

Practical notes

Fused frames are an endgame part, so the inputs are already advanced by the time you build the line. Heavy modular frames and aluminum parts both take time to automate, so start those chains first. Balance every input to the manufacturer, because this part has no tolerance for a starved feed.

Fused frames feed the space elevator, so a buffer prevents a stalled delivery when a tier deadline lands. Add manufacturers as demand grows rather than overclocking one machine, since the input chains set the ceiling. Keep the line near your aluminum production to shorten the belts.

Keep the line near aluminum production so the heavy belts stay short.

Common mistakes

  • One advanced input running dry
  • Too few manufacturers
  • Unbalanced inputs
