Materials / Data sheet

Polycarbonate PC

Guards and electrical housings.

In plain words

Good for

Guards and electrical housings.

Not for

Acids, alkalis and some solvents.

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.

The full data sheet

Every number on this page is copied from the filament maker's technical data sheet (V2.0). The PDF has the test methods and print settings.

The maker's data sheet prints a lower number at the light load than at the heavier load, which is the reverse of normal. We show it as printed and use the lower number on our materials table.

Test conditions from the data sheet: Mechanical Properties (Dry state); specimens annealed and dried at 80 °C for 12 hours before testing. 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.
