How they differ on the data
SUNLU Silk PLA+ runs 20°C hotter on the nozzle (window midpoints 200°C and 220°C), and the windows only touch at 210°C, so a shared profile has no margin. SUNLU Silk PLA+ runs 27°C hotter on the bed (window midpoints 28°C and 55°C), and the two windows share 5°C of range, so one profile can cover both. Fillamentum PLA Extrafill lists the wider window (55°C against 10°C).
Fillamentum PLA Extrafill ships on a 0.75 kg spool and SUNLU Silk PLA+ on 1 kg, so compare price per kilogram rather than per spool.
