Building Your First Sandustry Factory: A Complete Automation Guide

Why Sandustry Is Redefining Physics-Based Factory Automation

Factory automation games have traditionally followed a predictable formula: place machines, connect belts, and watch numbers go up. But Sandustry, developed by Lantto Games and published by Hooded Horse, flips that script by making every grain of sand a simulated physics object. Your Sandustry factory isn't just a series of connected nodes—it's a chaotic, living system where materials pile up, flow downhill, and clog your conveyors if you're not paying attention.

Released into Early Access on August 13, 2026, the game has already earned a 97% positive rating across 748 Steam reviews. Players are calling it a factory sim built inside the physics labyrinths of games like Noita, and that comparison couldn't be more accurate. Instead of clicking items into existence, you physically dig, grab, toss, and funnel materials through a destructible world.

Getting Started: Core Mechanics Every Sandustry Factory Needs

Your journey begins on planet PX47 as an interstellar prospector tasked with assessing gold yield potential. The early game teaches you the fundamentals through a guided tutorial that walks you through digging terrain, collecting sand, and processing it through your first machines.

Essential Early-Game Tools and Their Functions

The critical first step in any Sandustry factory setup is establishing a reliable wet sand supply. You need water to convert regular sand into wet sand, which then goes through shakers to extract gold and residue. Community reports indicate that water sources deplete over time, so planning your water management early saves significant headaches later.

Step-by-Step Early Factory Setup

1. Locate a water source near sand deposits to minimize transport distance
2. Dig sand using the left mouse button on soft terrain materials
3. Drop sand into water to create wet sand
4. Build shakers on foundations, positioned to receive wet sand drops
5. Place conveyor belts beneath shakers to catch falling materials
6. Add launchers to toss materials to collection zones or higher elevation
7. Research logistics as soon as you collect enough gold (approximately 50 gold)

Player experience suggests that building diagonally and stacking shakers creates a cascading effect that processes wet sand more efficiently than single-row configurations.

Mid-Game Production Chains: Scaling Your Sandustry Factory

Once your basic gold extraction loop is running, the tech tree opens up dramatically. The game introduces tier-two technologies that transform residue from a waste product into a valuable secondary resource stream.

Production Chain Progression

The flamethrower is a game-changer for your Sandustry factory. It burns residue, melts ice, and vaporizes water into steam. The kinetic press then takes that burnt residue and refines it into additional gold when dropped from sufficient height. This creates a closed-loop system where nearly every byproduct becomes a feedstock for another production chain.

Key Mid-Game Technologies to Prioritize

• Flamethrower: Unlocks residue burning and ice melting capabilities
• Kinetic Press: Converts burnt residue into gold, doubling your yield potential
• Conveyor Portal: Allows production lines to cross without mixing materials
• Sweeper Drone: Automatically collects materials scattered on the ground
• Cryoblaster: Produces infinite snow for freezing water or creating rain cycles

Player experience indicates that the conveyor portal is particularly valuable for dense factory layouts, as it lets you route different material types across each other without contamination—a common problem when using only standard conveyor belts.

Advanced Physics Tips for Optimizing Throughput

What sets Sandustry apart from other automation games is how deeply physics affects your factory's performance. Materials have weight, density, and flow characteristics that change based on pile size and composition.

Physics Behaviors That Impact Factory Design

One critical lesson from community reports: filters are essential for maintaining clean material streams. Without filters, wet sand and regular sand mix on your conveyor belts, gumming up shakers and reducing gold output. Setting filters to separate specific material types—accessible by pressing Alt while a filter is selected—keeps each production line running at peak efficiency.

Water Management and Rain Generation

Water depletion is one of the most significant challenges in mid-to-late game Sandustry factory operations. Ancient boiler runes scattered throughout caves provide a solution: boil water into steam, let it rise, and condense into rain using strategically placed blocks.

The process works as follows:

1. Use a flamethrower or thermal system to boil cave water
2. Direct rising steam using ceiling blocks
3. Steam condenses at high elevation into rain
4. Rain falls on sand, creating wet sand automatically
5. Collect wet sand and route it back to your shakers

This creates a renewable water cycle that sustains your factory indefinitely, though it requires significant infrastructure investment upfront.

Exploration: Finding Fluxite and Permanent Upgrades

Beyond factory construction, Sandustry rewards exploration with permanent upgrades that can't be farmed through normal production. Fluxite, a special upgrade material found deeper in the planet, unlocks tool enhancements that dramatically improve your efficiency.

Fluxite Upgrade Paths

Player experience suggests that upgrading grabber size should be your first Fluxite investment. Going from a 5×5 to a 33×33 grab area transforms how quickly you can excavate and relocate materials, effectively multiplying your manual throughput by several orders of magnitude.

Exploration also reveals ancient alien structures, mysterious colossal entities roaming the dunes, and hidden vaults containing powerful artifacts. These POIs often provide hints for advanced mechanics—like the boiler runes that teach rain generation—making cave diving essential for progressing your tech tree.

System Requirements and Platform Availability

Sandustry is available now on Steam with a 35% launch discount bringing the price to $9.74 through August 27, 2026. The game supports Windows, macOS, and SteamOS + Linux, with Steam Deck compatibility rated as Playable.

The developers plan to remain in Early Access for approximately one year, adding new buildings, resources, production chains, biomes, and technologies based on community feedback. Built-in modding tools also allow players to create custom maps, buildings, and even entirely new production processes.

FAQ

What makes a Sandustry factory different from other automation games?

Unlike traditional factory games where items exist as abstract data, Sandustry simulates every material as a physics object. Sand piles up, flows downhill, clogs conveyors, and interacts with water, fire, and gravity. This means your factory design must account for material behavior, not just machine connections.

How do you manage water in a Sandustry factory?

Water depletes when you use it to create wet sand. To sustain long-term operations, locate ancient boiler runes in caves, boil water into steam using a flamethrower, and direct rising steam with overhead blocks to condense into rain. This creates a renewable water cycle that keeps your wet sand supply flowing.

What is Fluxite and why is it important for your Sandustry factory?

Fluxite is a special upgrade material found deeper underground. Mining it permanently unlocks tool upgrades like increased grabber size, faster digging speed, and material scanning. These upgrades can't be farmed through normal production, making cave exploration essential for maximizing factory efficiency.

Is Sandustry worth buying in Early Access?

With a 97% positive rating across 748 reviews at launch, Sandustry is already highly polished. The developer plans a year of Early Access with community-driven content additions. At $9.74 with the launch discount, it offers substantial value for fans of physics-based automation and sandbox building games.
