Sandustry Synthesizer Guide: How to Make Aurixite
Quick answer
The Synthesizer is a late-game Energy machine. Its key current use is turning Florinol into Aurixite, which then feeds the Shaker → Auralite → Aura Extractor chain.
Quick answer
Use the Synthesizer after you can produce clean Florinol and enough Energy. The important current route is:
Florinol → Synthesizer → Aurixite → Shaker → Auralite → Aura Extractor
Do not place the Synthesizer before your Florinol line is stable. Most “Synthesizer not working” problems are upstream liquid, Energy, or output-space problems.
Unlock and input checklist
| Requirement | Why it matters |
|---|---|
| Tier 6 / late Research access | The official Research page places Synthesizer at the final tier |
| Florinol supply | Official Florinol notes list Synthesizer as a later use |
| Energy support | Research describes the Synthesizer as using Energy |
| Output space | Aurixite is a solid and needs a clean route to the next machine |
| Shaker nearby | Aurixite is processed by Shakers into Auralite |
Basic Synthesizer setup
- Build a dedicated Florinol buffer.
- Keep other liquids out of that buffer and Pipe network.
- Place the Synthesizer where Energy can reach it.
- Route Florinol into the machine.
- Give Aurixite an output path that does not mix with Gold, Seed, or Residue.
- Feed Aurixite to a Shaker for the Auralite step.
Aurixite behaves unlike many loose solids and may not flow into neat heaps, so leave more output space than you think you need.
Why the Synthesizer is not working
| Symptom | Likely cause | Fix |
|---|---|---|
| No output | No Florinol input or no Energy | Check the liquid buffer and power path first |
| Wrong material in the input | Shared liquid line contaminated the feed | Use a Florinol-only Pipe network |
| Aurixite piles badly | Output area is too tight | Open the exit and avoid dead corners |
| Auralite chain stalls | Aurixite is not reaching a Shaker | Place the Shaker close or add a visible transfer lane |
| Aura Extractor seems unrelated | The chain has not reached Auralite yet | Finish Aurixite → Shaker → Auralite before debugging Aura |
Where Synthesizer fits in progression
The Synthesizer is not an early Gold machine. It belongs after you have:
- a stable Flower/Amethelis line;
- Dry Amethelis and Florin control;
- Florinol condensation;
- Energy storage or generation;
- a plan for Aurixite and Auralite output.
If you only need Energy, finish the Florinol Battery loop first. If you are pushing into Aura progression, reserve space for the full Auralite chain.
