Endgame Logistics · Resource Regeneration
After stripping surface dunes to chase the 1 Million Gold milestone, countless factory engineers hit a devastating wall: finite natural sand runs out entirely. In Sandustry, the true endgame requires unlocking renewable geology. By anchoring a subterranean Stratacore node, carving renewable Soil blocks with Precision Lasers, and routing gravel byproducts through Prefabulators and Sifters, you can generate a continuous, 100% automated infinite sand pipeline.
Quick answer
To automate infinite sand in late-game Sandustry, locate and activate a subterranean Stratacore node. The Stratacore continuously regenerates solid Soil tiles in a 3x3 radius. Mount a Precision Laser to slice regenerated Soil blocks horizontally into loose rubble, feed the falling pixels into a Prefabulator to crush them into gravel, and run them through downward-slanted Shakers to extract pure, renewable Sand for non-stop Gold and glass loops.
01
In Sandustry, early-game engineers treat sand as an infinite convenience—it blankets the starting biome, fills mountain passes, and seems boundless. However, players pursuing the 1 Million Gold milestone or mega-scale glass factories inevitably encounter the Sand Wall: every grain of surface desert is finite.
Once dunes are cleared, quarrying bedrock yields only hard stone and copper ore. The game's progression requires transitioning from surface extraction to renewable subterranean geology powered by Stratacore blocks.
02
The Stratacore is an indestructible ancient geological engine located in mantle caverns. When energized by nearby thermal gradients or tapped with extraction drills, it continuously generates solid Soil terrain blocks in its immediate 3x3 perimeter.
Regeneration occurs at a baseline pace of 15 to 20 blocks per minute. However, the core contains a strict stall condition: if newly generated Soil blocks are not cleared, physical contact stops the regeneration cycle until surrounding space is reopened.
03
Mechanical pickaxes and mining drones are too clumsy to maintain a steady regeneration cycle without damaging adjacent conveyor framing. The optimal automation tool is the Precision Laser.
Position a single Precision Laser on a rigid mounting frame 2 tiles away from the Stratacore crown, firing horizontally across the top boundary. The moment a Soil block materializes, the laser beam shears it instantly into loose soil particles that tumble downward under natural gravity.
04
Falling soil rubble drops through a funnel hopper into a Prefabulator, which pulverizes compacted dirt into granular soil at a 1:1 ratio. The pulverized output feeds a 2-stage downward-slanted Shaker bank.
Shakers separate raw Soil into pure Sand (~75% yield) and coarse Gravel (~25% yield). A secondary return loop re-routes coarse gravel into a secondary crusher, achieving a near 100% mass conversion into pure industrial sand.
05
A single tuned Stratacore facility outputs 60 to 80 pure Sand per minute. This rate perfectly balances two standard Shaker gold loops operating with 25-block Kinetic Press drops.
Never construct more than two smelters per Stratacore line. Overbuilding downstream machinery creates an illusion of bottlenecking, when in reality machines are simply starving for input particles.
| Stage | Machinery Requirement | Throughput Rate | Operational Mandate |
|---|---|---|---|
| Core Regeneration | 1x Subterranean Stratacore | 15-20 blocks/min | Keep 3x3 clearance; insulate with Basalt walls |
| Laser Carving | 1x Precision Laser (Horizontal) | 15-20 cuts/min | Continuous horizontal pulse over core crown |
| Primary Crushing | 1x Prefabulator | 30 items/min capacity | Breaks falling soil chunks into granular rubble |
| Secondary Sifting | 2x Diagonal Shakers | 60-80 pure Sand/min | Separate Sand (output) from Gravel byproducts |
| Gravel Feedback | 1x Loop Conveyor to Pulverizer | 15-20 gravel/min | Re-crush gravel into sand; zero mass wasted |
Questions answered
Surface dunes and desert sand are finite. Once mined out, you must automate Stratacore nodes deep underground. Stratacores continuously regenerate solid Soil, which can be carved by Precision Lasers and sifted into unlimited Sand.
A single Stratacore generates terrain at approximately 15-20 blocks per minute. Exactly 1 Precision Laser paired with 1 Prefabulator perfectly matches this regeneration rate without wasting electrical power.
Stratacores stop regenerating if the surrounding 3x3 footprint is already filled with solid blocks or if loose uncollected rubble accumulates in the extraction zone. Ensure automated conveyor collection or vacuum hoppers clear fallen pixels immediately.
No! In Update #3, Lava has a high density of 200 and actively dissolves soft geological terrain. Always encase your Stratacore sand refinery in non-reactive Basalt or Cinder blocks to prevent catastrophic magma leaks.
Excess copper is common because copper veins are vast. Siphon extra power from copper battery banks to run high-wattage Precision Lasers and Stratacore crushers, converting abundant electrical energy into infinite sand throughput.
