Is Sunlu filament good?

SUNLU is a budget brand these threads already print, with a real failure mode when the gcode was tuned for a different brand. Budget filament, eSUN, and filament quality are the neighboring pages. Under-extrusion is the Hatchbox comparison.

The three rows

The catalog brand is SUNLU. PLA lists 190–230 °C (374–446 °F) and a bed of 50–70 °C (122–158 °F). PETG lists 220–250 °C (428–482 °F) and 70–90 °C (158–194 °F). ABS lists 230–260 °C (446–500 °F) and 90–110 °C (194–230 °F). Drying is blank on all three. PLA, PETG, and ABS are the hubs. SUNLU PLA+ has no listed nozzle or bed, so it stays off the table. Hatchbox PLA lists the same 190–230 °C (374–446 °F) and 50–70 °C (122–158 °F) as SUNLU PLA.

What the threads report

r/BambuLab 1b9r3zz is a request for budget PLA because SUNLU is sold out. The poster says they love SUNLU from a previous printer. The retrieved replies recommend other brands. That is a preference, not a measured defect rate.

r/BambuLab 150296l asks about the AMS. The score-34 comment says zero issues: a spool one week old and a spool two years old both print. The replies treat the ages as a joke about children. Read as written, the comment is about spools. AMS is the loader limit.

r/FixMyPrint 12c7d7c shows SUNLU under-extruded and discolored next to Hatchbox on the same gcode. The leading comment says identical gcode across brands is the problem, and that SUNLU wants slightly higher temperatures than Hatchbox for PLA and for PLA+. A score-17 comment keeps one profile per brand and names SUNLU in that rotation. A score-10 comment likes SUNLU PLA+ and puts a recurring sale at $14/kg. The catalog has no price per kilogram, so $14/kg stays that comment.

r/3Dprinting 1va32rs received SUNLU Green PETG and Green TPU that were darker than the old lime. A score-101 comment says the bright green ABS changed too, and that high-speed PLA in the same name is less saturated. A score-32 comment says ABS and PLA greens not matching is common. A score-19 comment thinks SUNLU manufactures filament for other companies. That last line is the comment's belief.

r/BambuLab 1wd7c4m asks if silk gold always looks bad. The leading comment says lots of SUNLU silk gold looks like gold when it is printed slow and hot. A score-31 comment repeats slow and hot. Neither comment gives a temperature.
