Printing Proto-Pasta PLA

Proto-Pasta PLA in Black runs on the PLA profile below, and this listing is a 0.5kg spool. PLA is best suited to everyday prototypes, models, and indoor parts that won't face heat or heavy stress. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.

Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our PLA filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.

Nozzle Compatibility

This is an unfilled plastic, so it is not abrasive: a brass nozzle works and lasts, and so does hardened steel. With hardened steel, print about 5 to 10°C hotter.
