Static-dissipative carbon-filled nylon for electronics tooling. Strong in plane at 84 MPa but only 21.5 MPa in Z — a quarter of XY, the most anisotropic material in this group.
This material is for electronics handling where ordinary rigid plastic would accumulate charge: PCB fixtures, storage supports, housings and production tooling. Its defining property is controlled electrical dissipation, combined with nylon stiffness and heat resistance. Polymaker specifically identifies PCB manufacturing and storage among the intended uses of PA612-ESD. Ordinary carbon-filled nylon is not automatically dissipative; many ordinary nylon composites remain electrically insulating.
The mechanical tradeoff also differs from unfilled nylon. This grade has low elongation and a particularly weak printed Z direction, so thin clips and heavily loaded layer-crossing bosses deserve attention. The finished part and its contact or grounding arrangement need resistance checks: the spool designation alone cannot establish the performance of an entire static-control fixture.
FDM · Polymaker Fiberon PA612-ESD, carbon-filled PA612 · Manufacturer-listed applications
Polymaker lists PCB manufacturing, PCB storage and industrial fixtures as intended applications. The point is to combine mechanical support with controlled charge dissipation; this is a manufacturer application recommendation rather than a documented customer installation.
