RimWorld How To Get Plasteel: The Ultimate Resource Farming Guide

Plasteel is the premier high-tech building material in RimWorld, essential for crafting advanced components, powerful spacer-tier weaponry, and high-performance reconnaissance or marine armor. Securing a reliable supply requires transitioning from opportunistic scavenging to systematic mining, deep-drill scanning, and orbital trade automation.

Strategic Preparation and Resource Checklist

Before launching an aggressive plasteel acquisition campaign, your colony must establish the technological and logistical infrastructure required to process, transport, and protect high-value materials. Plasteel carries a significant market value, making your storage zones prime targets for raiders if security is neglected.

• Essential Gear and Infrastructure: Multi-analyzer research bench, deep drills, ground-penetrating scanner, heavy mining equipment, and long-range mineral scanner.
• Mandatory Prerequisite Knowledge: Multianalyzer technology, deep drilling research, microelectronics, and advanced fabrication capabilities.
• Colony Benchmarks: Minimum of one dedicated full-time crafter or miner with level 8+ skills, stabilized power grid capable of supporting heavy energy drains, and fortified perimeter defenses to absorb wealth-driven raid spikes.

Step-by-Step Plasteel Extraction Workflow

Step 1: Researching Advanced Scanning Technologies

1. Build a hi-tech research bench and power it continuously to begin unlocking spacer-tier technology paths.
2. Research microelectronics to unlock the multi-analyzer, which serves as the gateway for all advanced technological milestones.
3. Construct the multi-analyzer adjacent to your hi-tech research bench to unlock deep drilling, ground-penetrating scans, and advanced fabrication.

Pro-Tip: Place your research benches in a clean, well-lit room with sterile tiles if possible to maximize research speed multipliers and minimize technician downtime.

Step 2: Uncovering Underground Plasteel Deposits

1. Construct the ground-penetrating scanner anywhere under an unroofed outdoor sky tile and connect it to your main electrical grid.
2. Assign a high-intellect colonist to operate the scanner; higher intellectual skill drastically reduces the time required to discover underground resources.
3. Wait for the scanner to ping a deposit, which will reveal subterranean resource veins across your local map tile accompanied by an on-screen alert.

Warning: Ground-penetrating scanners consume a massive amount of base power (350W constant draw), so ensure your geothermal generators or battery banks can handle the continuous load before deployment.

Step 3: Deploying Deep Drills and Managing Infestations

1. Build deep drills directly over the revealed plasteel resource tiles using steel and components.
2. Connect the drills to power and assign colonists with adequate mining skills to operate them until the tile is completely exhausted.
3. Monitor your hazard levels closely, as deep drilling carries a constant operational risk of triggering underground insect infestations directly beneath or adjacent to the drill site.

Pro-Tip: Pave the perimeter around your deep drills with wooden flooring or leave incendiary traps nearby to quickly deal with sudden insectoid spawns before they breach your interior defensive lines.

Plasteel Acquisition Methods Comparison

Common Mining Failures and Field Fixes

• Resource Depletion Stalls Production:
  
  
  • Root Cause: Local map surface pockets and initial deep drill veins have been completely mined out, halting spacer-tier manufacturing.
  • Actionable Fix: Research and construct the long-range mineral scanner to dispatch mining caravans to temporary map tiles for distant plasteel nodes.
• Catastrophic Insectoid Hive Spawns:
  
  
  • Root Cause: Deep drilling operations triggered underground bug triggers in enclosed mountain or underground drilling chambers.
  • Actionable Fix: Maintain a dedicated skirmish squad equipped with shotguns, heavy armor, and incendiary weapons stationed near drilling zones to eliminate emergent infestations instantly.
• Colony Wealth Inflation Triggering Overpowered Raids:
  
  
  • Root Cause: Hoarding thousands of unprocessed plasteel units dramatically increases colony net worth without converting it into defensive power.
  • Actionable Fix: Immediately utilize acquired plasteel to craft marine armor, charge rifles, and advanced defenses to offset the combat rating penalty of stored wealth.

Frequently Asked Questions

How do I get plasteel early in a RimWorld playthrough?

Early-game plasteel is best acquired by trading silver or manufactured drugs with visiting orbital trade ships and friendly faction caravans. You can also occasionally find small unmined surface veins on certain tile types or deconstruct crashed mechanoid ships.

Can I craft plasteel from regular steel at a workbench?

No, plasteel cannot be crafted from basic steel using vanilla crafting benches or fabrication benches. It must be mined from specialized subterranean deposits, traded for with faction bases, or harvested by recycling hostile mechanoids.

Do deep drills run out of resources permanently?

Yes, every deep drill resource node holds a finite amount of plasteel. Once the underlying tile is exhausted, the drill will output a notification stating the resource vein is depleted, forcing you to relocate the drill to a new scanner-detected location.

What is the most efficient way to farm plasteel without dying to raids?

The safest method is utilizing orbital trade ships while keeping your immediate stockpiles low and converting your silver into high-value portable goods. Once your defenses are fully modernized, transition to deep drilling backed by localized killboxes.
