Polycarbonate on the Bambu Lab P1S
Yes, with a couple of cautions. Enclosed CoreXY workhorse. Adds ABS and ASA to the easy list.
Polycarbonate works on the Bambu Lab P1S, mind a couple of things
Use the lower end of the bed rangePrinter
Some Polycarbonate spools ask for up to 120 °C on the bed; the Bambu Lab P1S reaches 100 °C. Set the bed near 100 °C and add a glue stick if corners lift.
Enclosed chamber, exactly what this material wantsPrinter
The Bambu Lab P1S is a closed box, so Polycarbonate cools slowly and evenly instead of warping.
Keep the spool dryMaterial
Polycarbonate soaks up moisture from the air, and damp filament prints rough and stringy. If that happens, dry the spool at 80-90 °C for 6-8 h and store it sealed with desiccant.
Buying the CF version of Polycarbonate?
Carbon-fiber filament sands down the Bambu Lab P1S’s stock nozzle. Plain Polycarbonate is fine; for the CF variant, fit a hardened steel nozzle first (a cheap swap).
Safe starting ranges for Polycarbonate as a family, not gospel. Each spool below has its exact manufacturer numbers, the dated source, and one-click slicer settings on its page.
