ARC Synthetic Resin is a rare recyclable material in Arc Raiders that drops from destroyed ARC machines. On its own, it isn't especially useful — recycling one yields 14 Plastic Parts, salvaging gives 9, and you can sell it for 1,000 coins. But you need 10 of them for the fourth phase (Dominant Dangers) of the Trophy Display project, which rewards a Bobcat IV. That makes farming resin a priority for anyone pushing through that questline.
Quick answer: Kill small flying ARC enemies like Wasps, Snitches, and Spotters in open maps such as Spaceport or Buried City, or search Baron Husks, Deforester Husks, and Arc Probes scattered across the map — especially during the Electromagnetic Storm weather condition, which spawns large clusters of Probes and Couriers.
All confirmed ARC Synthetic Resin drop sources
ARC Synthetic Resin drops exclusively from ARC-category loot. You obtain it by scavenging the wreckage of destroyed ARC machines, whether you destroyed them yourself or found them already downed. The full list of confirmed sources covers a wide range of enemies and environmental objects.
| Source | Type | Difficulty |
|---|---|---|
| Wasp | Kill & loot | Low |
| Snitch | Kill & loot | Low |
| Spotter | Kill & loot | Low |
| Turret | Kill & loot | Medium |
| Sentinel | Kill & loot | Medium |
| Shredder | Kill & loot | Medium–High |
| Queen | Kill & loot | High |
| Matriarch | Kill & loot | High |
| Baron Husk | Scavenge (breach) | Low (already dead) |
| Deforester Husk | Scavenge (breach) | Low (already dead) |
| Arc Probe | Scavenge (breach) | Low |
| Arc Courier | Scavenge (breach) | Low |
The drop is not guaranteed from any single enemy. It's a rare roll each time, so volume matters more than picking one "perfect" target.
Fastest farming methods for ARC Synthetic Resin
There are two broad strategies, and combining them in a single raid is the most efficient approach.
Hunt small ARC flyers in open areas. Wasps, Hornets, Snitches, and Spotters are plentiful in maps like Dam Battleground, Buried City, and Spaceport. They go down quickly with minimal ammo investment, and roughly one in three Wasps or Hornets will drop resin. Bring seeker grenades to speed up kills on flying targets. Because these enemies are weak, you can chain kills without burning through your loadout or attracting too much attention from other raiders.
Breach Husks, Probes, and Couriers. Baron Husks and Deforester Husks are the downed ARC wrecks you find on the ground — they can be breached and searched without any combat. Arc Probes and Arc Couriers work the same way. Not every one contains resin, but they're free loot with zero risk. Keep an eye out for small smoke plumes marking already-destroyed machines; those wrecks are easy to miss but can still hold resin.
Electromagnetic Storm runs
The single best condition for farming ARC Synthetic Resin is the Electromagnetic Storm weather modifier. When this is active on a map, Arc Probes and Arc Couriers spawn in clusters of three all over the environment. You can breach and search them while dodging lightning and avoiding active ARC patrols. Players have reported pulling more than 10 resin in a single raid under this condition, which is enough to complete the entire Trophy Display requirement in one go.
Check the map selection screen before deploying. If Spaceport or another map is showing the Electromagnetic Storm modifier, prioritize that run.
Shredder farming on Stella Montis
For a more combat-oriented approach, Shredders on Stella Montis offer a reliable loop. The Archive area on that map consistently spawns three Shredders, and they respawn at roughly eight-minute intervals. A shotgun handles them efficiently, and every second or third kill tends to yield two resin along with fresh shotgun ammo — letting you sustain the loop indefinitely without needing to extract and re-deploy. The Archive is also relatively sheltered from other players, reducing the risk of getting jumped mid-fight.
High-tier ARC enemies and boss drops
Queens and Matriarchs drop ARC Synthetic Resin at noticeably higher rates than smaller machines. One Queen kill can yield seven or more resin in a single loot pool. The tradeoff is obvious: these are the hardest fights in the game, requiring a full loadout and ideally a squad. If you're already planning to take on a Queen or Matriarch for other Trophy Display materials like cores, the resin you pick up along the way can save you several farming runs.
Bastions and Bombardiers are sometimes suggested as resin sources, but player experience with these is inconsistent. Some raiders report getting resin from Bastions; others have killed ten or more without a single drop. Smaller, more numerous targets tend to be more reliable over time.
Item stats and recycling output
ARC Synthetic Resin weighs 1.0 units and occupies a tier-3 inventory slot. Recycling produces 14 Plastic Parts, while salvaging yields 9. The sell value is 1,000 coins. Outside of the Trophy Display project, there's no crafting recipe that requires it, so if you've already completed Dominant Dangers, feel free to recycle or sell any extras you come across.
If you're still working toward the Trophy Display, resist the urge to recycle resin as you find it. The 10-unit requirement sneaks up on you, and re-farming from scratch is tedious given the drop rates.
