We print these too, but have no data sheet figures to compare them here. Ask an engineer whether one suits your part: Nylon PA12, PA6, PC-ABS, PC-PBT, PPA-GF.

Heat deflection to ISO 75, tensile to ISO 527 and impact to ISO 179, in the layer plane (X-Y), on Bambu Lab's own test specimens. Most were annealed before testing; PPA-CF and PPS-CF were tested as printed. Bambu Lab gives these values for design reference and comparison only: a printed part depends on its shape, orientation and settings. UL 94 ratings come from the test reports linked on Bambu Lab's product pages, at the thickness shown.

Sun, water, chemicals, impact, stiffness, wear and accuracy in the recommendations are our own 0–3 ratings: read from the data sheets where they give a figure or a table (water absorption, impact including the notched value, modulus, chemical resistance) and from our experience where they do not (sun, wear, accuracy).

Questions

Which filament is best for parts outdoors?

ASA: it is made for long-term outdoor use and holds its colour and strength in the sun. PETG also copes outdoors; PLA softens in a hot car or a sunny window and is not for outdoor parts.

Which filament takes the most heat?

Of what we print, PPS-CF has the highest heat deflection, then PPA-CF, PET-CF and the carbon- and glass-filled nylons. For everyday parts up to about 80 °C, ASA or PC are usually enough; at 100 °C both are at their heat deflection limit.

Can you print parts for contact with food?

No. The filaments we print are not food-grade, and a printed surface holds bacteria in its layer lines. We do not make parts for food contact.
