The PLA compromise is a comment, not the 2016 paper. r/BambuLab 1ezdri8, score 2, describes a resin printer in a grow tent with a fan pushing odor out. The excerpt is cut off. The other score 2 describes a growing enclosure and an exhaust, says the smell is gone with it, and the excerpt is cut off. r/prusa3d 1gdjje6, score 95, ranks external ventilation above HEPA plus activated carbon, then HEPA, then open doors and airflow, then nothing. Score 34 says it is safe, but with PLA the fumes are minimal, and that an open window can add humidity, so store filament in a bag. No excerpt was supplied for r/3Dprinting 1kvsas5, r/BambuLab 1l5duf9, or r/BambuLab 1j6q18m.",
