Printing Notes

PLA Basic is our everyday value PLA, with 45 – 49 MPa tensile strength and a 53 °C heat deflection temperature. Use it for prototypes and display pieces, and keep finished parts out of hot cars.

The XL's heatbed is made of 16 individually controlled tiles and heats only the area under and around your parts, so one small part on the 360 × 360 mm bed does not heat the whole sheet.

PLA Basic ships on a thinner standard spool. Check that it sits square and turns freely on the XL's spool holder before you start a long print.

Multi-tool: Prusa's default minimal purge for PLA-only jobs is 15 mm³ on the wipe tower. Leave Ooze prevention switched on so parked toolheads drop to their idle temperature instead of leaking filament.

Slicer: PrusaSlicer with the Prusa XL printer profile and a 0.4 mm nozzle. Dry the filament at 50 °C for 5 h before a long print; every figure above assumes dry filament.

Troubleshooting

Stringing between parts: Dry the roll, then drop to 205 °C. On multi-tool jobs, check that Ooze prevention is on so idle toolheads are not sitting at print temperature.

Corners lifting on large, flat parts: Wash the sheet with warm soapy water, keep the bed at 60 °C and add a brim in PrusaSlicer.

Soft or drooping overhangs: Keep the part cooling fan at 100 % and drop the nozzle 5 °C. Slow the outer walls if the overhang is steep.
