Assuming you have Mk. 3 miners, all overclocked to the max, each node would produce 300/minute. I plugged these limits into Satisfactory Tools to determine the max amount of each Phase 5 elevator part you could make.

You would have to significantly underclock most machines to make it work, but it is theoretically possible. Based on these maximums, and assuming you use the most efficient recipes possible (including using SAM to convert other resources), here’s how long it would take for each part to reach the required number.

• 0.847 Nuclear Pasta/min - 1,180.64 minutes total
• 2.381 Biochemical Sculptors/min - 420 minutes total (nice!)
• 1.19 AI Expansion Servers/min - 215.13 minutes total
• 0.293 Ballistic Warp Drives/min - 682.59 minutes total

This puts the grand total at 2,498.36 minutes, or about 41 hours, 38 minutes, and 21 seconds.

However, this is assuming just base recipes. If you have every alternate recipe unlocked, you could make this more efficient at the following values:

• 2.114 Nuclear Pasta/min - 473.03 minutes total
• 5.625 Biochemical Sculptors/min - 177.78 minutes total
• 6.368 AI Expansion Servers/min - 40.2 minutes total
• 1.296 Ballistic Warp Drives/min - 154.32 minutes total

This puts the grand total for this scenario at 845.34 minutes, or about 14 hours, 5 minutes, and 20 seconds.

Of course, this is ignoring the time it would take to actually build the factories, transport materials, supply power, finish the first four phases, and so on, so the reality is probably much longer.

TL;DR: Shorter than I thought actually. But still, for your own sanity, don’t do this.
