Overview
Premium water-soluble support material engineered for compatibility with high-temperature materials like Nylon and PC. Dissolves 3-5× faster than PVA and bonds better to semi-crystalline polymers that PVA won't adhere to.

Pros
- Dissolves 3-5× faster than PVA in warm water
- Compatible with PA, PC, ABS, ASA — materials PVA can't support
- Better inter-layer adhesion to nylon
- Clean dissolution with no residue
- Less hygroscopic than PVA
Cons
- Very expensive — 3-4× cost of PVA
- Limited availability
- Requires dual-extruder setup
- Printing window is narrow
- Cannot be reused
Best For
- Complex support structures for PA
- PC
- ASA|Dissolvable supports in industrial printers|Multi-material engineering prototypes|Overhangs and bridges in high-temp prints
Avoid For
- Standard PLA/PETG (use PVA — cheaper)|Single-extruder machines|Cost-sensitive projects|Simple geometries that don't need dissolvable supports
Storage
Store in vacuum-sealed bag with desiccant. Less sensitive than PVA but still hygroscopic. Dry at 50°C for 4h if moisture-affected. Use within 6 months of opening.
