Do not choose nylon support solely because it dissolves in water. The support must survive the printing conditions, adhere where needed and come away without compromising the model.
3DXTech’s support matrix maps its nylon families to named support products. Use such a matrix as a starting point within that supplier’s system, then confirm the exact formulation and current processing instructions.
A named pair—and a useful exclusion
| Model material | Support to investigate | Boundary |
|---|---|---|
| Polymaker PolyMide PA12-CF | PolySupport for PA12, named in its technical data sheet | Breakaway removal; the interface must be reachable. |
| Polymaker PolyMide CoPA | Do not transfer the PA12 recommendation | Polymaker excludes CoPA from PolySupport for PA12. |
The PolySupport for PA12 data sheet names PA12-CF. The product instructions specify mechanical removal, dry handling and a 270–300°C nozzle range for the support; they recommend separate nozzles because material switching can clog a single nozzle. Those requirements must fit both the model material and the machine.
The older 3DXTech matrix uses the broad AquaTek family name for plain, carbon-filled and glass-filled nylon. Its former X1 URL now resolves to a PVA product page with different wording. Treat that as a reason to confirm the exact current product pairing, not permission to substitute any PVA spool.
Check the pair, not two separate spools
| Compatibility question | Required answer |
|---|---|
| Model material | Exact nylon and reinforcement, if any |
| Support | Explicitly documented pairing |
| Printer | Supported tool-change or material-change process |
| Thermal environment | Both materials tolerate the planned bed and chamber conditions |
| Removal | Approved process and access to the interface |
Can ordinary PVA support every nylon?
No compatibility follows from “water soluble” alone. Verify the thermal and adhesion requirements for the exact pair. If the supplier does not document it, treat it as unresolved rather than borrowing settings from a PLA job.
Could I avoid a second material?
Compare orientation and accessible same-material supports first. A small geometry change may avoid a trapped support cavity. Use the orientation checklist before changing consumables.
Test one difficult interface
Print a representative supported region and complete the documented removal process. Check both surface quality and fit afterward. If water exposure is involved, include nylon conditioning in the dimensional decision rather than measuring only the dry, freshly printed sample.
