Vapor smoothing goes well beyond powder bed nylon. AMT’s consumables page lists a much wider set of materials. Here is what is published beyond PA11, PA12, TPU and PP.

## With FA326 (SF50 and SF100)

- **Rigid plastics:** PA6, ABS, PC, PBT, ASA, PETG, as well as PA11 and PA12.
- **Elastomers:** TPE as well as TPU.
- **Composites:** glass, carbon or mineral-filled.
- **Technologies:** SLS, MJF, SAF, and extrusion (FFF, FDM).

FA326 is listed as compatible with 100+ thermoplastics.

## With PostPro Pure

- **High performance:** ULTEM and ONYX, including FDM parts in those materials.
- **Composites:** glass, carbon or mineral-filled.
- **CNC-machined plastics:** PC, PEI and PMMA. Yes, machined parts as well as printed ones.

## Before you try something new

- Check the grade-level compatible materials lists on the [documents page](https://amtechnologies.com/resources/documents/).
- Ask AMT, or [send parts for a benchmark](https://benchmarking.amtechnologies.com/). Results on a new material are worth sharing here.

**Over to you:** what is the most unusual material you have smoothed? Tell us what worked and what did not.
