Essential Automation Basics
To build a perfect factory in Sandustry, you must master the movement of resources. Relying solely on gravity often leads to clogged conveyor belts and inefficient production lines. The key to high-yield automation lies in the strategic use of Fans, Launchers, and Filters.
Fans are indispensable for pushing resources up inclines or across gaps where conveyors would fail. When setting up your initial seed lines, use fans to ensure a steady flow into your processing units. For more complex sorting, Launchers can toss items over walls or into specific processing vats, while Filters ensure only specific materials, like dry metal leaves, pass through to the next stage.
Always use Copy/Paste tools to replicate successful sections of your factory. If a specific fan arrangement clears a jam effectively, duplicate that pattern rather than rebuilding manually.

Thermal Management & Pyro Systems
Managing heat is critical for mid-to-late game progression. The Pyro Dispenser is a powerful tool that fires a burst of flames every 3 seconds, but it consumes heat from an adjacent Thermal Buffer. To sustain this, you need a reliable heat source.
Lava is the most effective early-game heat source. When lava is placed or generated, it releases flames that can charge Thermal Buffers. However, direct contact with lava can sometimes consume the liquid source. Instead, build a large surface area of lava beneath your buffers. The flames popping up from the surface will charge the buffers slowly over time without depleting the lava instantly.
| Component | Function | Heat Source | Best Use Case |
|---|---|---|---|
| Pyro Dispenser | Fires flame bursts every 3s | Adjacent Thermal Buffer | Automated burning of debris |
| Thermal Buffer | Stores heat energy | Lava flames / Burner Belt | Powering Pyro Dispensers |
| Burner Belt | Heats items on belt | Self-generating | Drying wet items / Smelting |
| Lava Pool | Generates flames | Geothermal / Creatures | Charging Thermal Buffers |
Do not place Thermal Buffers directly inside deep lava pools, as they may consume the lava block entirely. Place them above the lava surface to catch the rising flames.
Advanced Resource Processing
Converting raw materials into valuable products requires multi-step processing. A common bottleneck is processing Metal Leaves, which must be dried and then smelted.
The Steam Dryer Method:
- Wash & Dry: Move wet leaves through a water vat, then use a Steam Dryer. Steam causes wet leaves to dry and float upwards.
- Filtering: Use a filter wall that only allows Dry Metal Leaves to pass. This separates your product from waste.
- Gas Conversion: Burn the dry leaves using a Burner Belt or Pyro Dispenser. This turns them into gas.
- Condensing: Use the Condenser with snow to convert gases back into liquids (like liquid Fluorine) for battery power.
Setup Steam Generation
Create a steam source by melting snow on a Burner Belt or piping water over hot lava. Direct this steam into your drying chamber.
Separate Dry Leaves
Build a filter wall that permits only dry items. This ensures wet debris is recycled or disposed of automatically.
Automated Burning
Feed dry leaves into a burning chamber. Use Logic Gates (once unlocked) to activate the Pyro Dispenser only when items are present, saving heat.
Condense Output
Capture the resulting gas in a sealed chamber. Use vents with snow to condense the gas into liquid Fluorine for high-tier energy storage.
Creature Utilization & Farming
Creatures are not just ambient wildlife; they are vital for automating elemental resources. Using the Coraller, you can capture and farm specific species for infinite water and lava production.
Lumling Farms: Lumlings excrete water, making them essential for hydration loops. Build a fenced enclosure with Gold Foundations (to prevent escape) and use a Coraller to capture them. Once released inside the pen, they will passively generate water, which can be drained via vents or pipes into your factory.
Pyro Farms: For lava production, seek out Pyro creatures. Similar to Lumlings, they generate lava which can be used to fuel your thermal buffers indefinitely. This removes the need to constantly mine new lava sources.
| Creature | Resource Produced | Capture Tool | Automation Method |
|---|---|---|---|
| Lumling | Water | Coraller | Fenced pen with drainage vents |
| Pyro | Lava | Coraller | Insulated pen with thermal buffer access |
| Shinelit | Light | Coraller | Decorative lighting for bases |
Connect your creature pens directly to your processing lines. For example, route Lumling water directly into your seed washers to create a fully closed hydration loop.
Factory Optimization Checklist
As you expand your operations in Sandustry, keeping your factory organized is crucial for performance and mental clarity. Use this checklist to ensure your base is running at peak efficiency.
Optimization Milestones:
- Unlock Logic Gates to automate burning only when items are present
- Replace manual lava dumping with automated Pyro creature farms
- Implement Copy/Paste tools to replicate effective fan arrays
- Construct a dedicated drying and condensing line for gas production
- Filter all gold into dedicated storage using Gold Foundations
Troubleshooting Common Issues
Even the best-designed factories encounter hiccups. Here are solutions to the most common problems players face when automating their sand empire.
Problem: Seeds Getting Stuck in Water If seeds are piling up in your washer instead of moving through, the water level may be too high or the output conveyor is blocked.
- Solution: Lower the water source or use Clearing Frames instead of standard conveyors to force movement through the liquid.
Problem: Thermal Buffers Draining Too Fast If your Pyro Dispensers are firing but buffers hit 0 heat quickly, your lava source is being consumed.
- Solution: Ensure lava is only touching the bottom of the buffer or use a wider surface area of lava so the flames charge the buffer without deleting the lava block.
Problem: Gas Leaking into Factory Gas from smelting can float everywhere and cause lag or unwanted reactions.
- Solution: Build a dedicated Gas Chamber with a roof. Use a Condenser vent with snow at the top of the chamber to turn the gas back into liquid immediately.
| Issue | Likely Cause | Fix |
|---|---|---|
| Items falling off belts | Belt speed too high / Sharp turns | Use Launchers to bridge gaps or slow down input |
| Flames not reaching items | Pyro Dispenser too far away | Lower dispenser or use Burner Belts for contact |
| Water shortage | No passive generation | Capture Lumlings for infinite water supply |
FAQ
Q: How do I get infinite gold in Sandustry?
Infinite gold requires a fully automated factory. You need to automate seed collection, wash them, dry the leaves, burn them into gas, and process the byproducts. Using captured creatures for infinite water and lava is the final piece to sustain this loop without manual resource gathering.
Q: What is the best way to generate heat for the Pyro Dispenser?
The most sustainable method is farming Pyro creatures or creating a large surface area of lava. Place Thermal Buffers above the lava so they catch the flames without consuming the lava source blocks directly.
Q: Why are my items not moving through the water washer?
Wet items tend to float and can get stuck on the surface or against walls. Use Clearing Frames or angled launchers to push items through the water mechanically, rather than relying on water flow alone.
Q: How do Logic Gates help in Sandustry?
Logic Gates allow you to activate machines (like Pyro Dispensers) only when specific conditions are met, such as an item being present. This prevents wasting heat and resources, making your factory significantly more efficient.
