Carbon-fiber nylon, stiff grade PA6-CF
Dry parts that take hard hits. The stiffest option.
In plain words
Good for
Dry parts that take hard hits. The stiffest option.
Not for
Wet or humid spots: it takes on water and loses stiffness. Strong acids or alkalis. Flame, sparks or high-current electrics.
Upright is weaker
A printed part is strongest along its layers (flat, X-Y) and weaker across them (upright, Z). The table shows both. We turn the part so the load runs along the layers.

Test conditions from the data sheet: Table headed 'Mechanical Properties' (no 'Dry state' label in this TDS); specimens annealed and dried at 80 °C for 12 h before testing; printed 280 °C nozzle, 100 °C bed, 100 mm/s, 100% infill. These are lab numbers for test bars, not a working limit for your part. The real limit depends on the load, the time at temperature and the shape, which is why we ask about all three.
