Is this right for your spool?

Here's how sure we are — and what to watch.

A hardened nozzle is recommended

LANDU PETG Sparkling is mildly abrasive — it'll wear a stainless nozzle over time. It still prints fine on stainless; switch hardness to Hardened for longevity.

Why these numbers

LANDU PETG Sparkling starts from Bambu's PETG Basic reference; LANDU's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
