  "updated": "2026-10-17",
  "shortAnswer": "SUNLU is a budget PLA the poster on the sold-out thread already likes, and one AMS comment reports a week-old spool and a two-year-old spool both printing. The same set of threads also shows brand-specific under-extrusion, a darker green than the old lime, and silk that a comment prints slow and hot.",

  "printerConsiderations": [
    "On r/FixMyPrint 12c7d7c Hatchbox is the control and SUNLU is under-extruded and discolored on the same gcode. The leading comment says each filament wants its own temperature and extrusion speed, and that SUNLU runs slightly hotter than Hatchbox for both PLA and PLA+.",
    "On r/BambuLab 150296l the question is SUNLU in the AMS. A score-34 comment says zero issues, with a spool one week old and a spool two years old. The replies joke that the ages sound like children. The sentence itself is about spools.",
    "SUNLU PLA+ has no nozzle and no bed in the Open Filament Database. The comment that likes PLA+ does not fill that blank."
  ],
  "pros": [
    "PLA, PETG, and ABS each have a stored range, so the brand question lands on rows.",
    "The AMS report and the under-extrusion report are both kept. One does not erase the other."
  ],
  "cons": [
    "A comment puts a recurring SUNLU PLA+ sale at $14/kg. The catalog price cell is empty, so that dollar figure stays a comment.",
    "The silk comment says slow and hot and gives no temperature. SUNLU silk is not given a number on this page."
  ],
  "community": "r/BambuLab 1b9r3zz asks for a budget PLA because most SUNLU PLA is sold out. The poster says they love SUNLU from an older printer. The retrieved suggestions name other brands. r/BambuLab 150296l asks about SUNLU in the AMS, and the leading comment reports no issues on a week-old spool and a two-year-old spool. r/FixMyPrint 12c7d7c shows SUNLU under-extruded next to Hatchbox on identical gcode. The leading comment says SUNLU needs slightly higher temperatures than Hatchbox for PLA and PLA+. A score-17 comment keeps a separate profile per brand, including SUNLU. A score-10 comment likes SUNLU PLA+ and quotes a recurring sale at $14/kg. r/3Dprinting 1va32rs asks if SUNLU changed its green. The poster received darker green PETG and TPU. A score-101 comment says yes, and misses the old bright green ABS. r/BambuLab 1wd7c4m asks if SUNLU silk gold always looks bad. The leading comment says it looks like gold when printed slow and hot.",

      "q": "Do SUNLU PLA and Hatchbox PLA list different nozzle ranges?",
      "a": "No. Both list 190–230 °C (374–446 °F) and a bed of 50–70 °C (122–158 °F) in the Open Filament Database. The slightly higher SUNLU temperature is a comment on r/FixMyPrint 12c7d7c, not a second catalog range."

    {
      "q": "What does SUNLU PLA+ list?",
      "a": "SUNLU PLA+ has no listed nozzle or bed in the Open Filament Database, so it is not ranked. SUNLU PLA lists 190–230 °C (374–446 °F) and 50–70 °C (122–158 °F). The budget-filament guide and the eSUN page are the neighboring brand questions."
