AE2 Crystal Science

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 26.1.2 · NeoForge⬇ Download for 1.21–1.21.1 · NeoForge⬇ Download for 1.20.1 · Forge
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Overview

Applied Energistics: Crystal Science (AECS) is an addon for Applied Energistics 2 that brings back the Purified Crystal concept and builds a full progression around it.

With a production chain of Dust → Seeds → Growth and dedicated machines (Grindstone / Pulverizer / Growth Chamber / Aggregator), you can mass-produce purified crystals for mid-to-late game crafting and energy generation.
On the other side, AECS adds stronger pattern execution and wireless channel solutions (Meteorite/Resonating Pattern Providers, Ender Emitter & Ender Broadcaster) to build more powerful automation.

All items and blocks added by AECS including crystals, machines, tools, and ME devices
