{"job_id": "ingest-001", "material": "ABS", "geometry_type": "warping", "env_temp": 20.0, "env_humidity": 40.0, "outcome": "failed_sag", "lesson": "ABS corners lifted in an open, cool room. ABS needs an enclosure and a 100-110C bed; without it, warping is near-certain regardless of settings.", "source": "ingested", "timestamp": "2026-05-22T09:00:00Z"}
{"job_id": "ingest-002", "material": "ABS", "geometry_type": "adhesion", "env_temp": 24.0, "env_humidity": 45.0, "outcome": "success", "lesson": "ABS first layer held with bed at 105C, brim, and fan off for opening layers. Draught control matters more than glue for ABS adhesion.", "source": "ingested", "timestamp": "2026-05-22T09:05:00Z"}
{"job_id": "ingest-003", "material": "TPU", "geometry_type": "stringing", "env_temp": 23.0, "env_humidity": 55.0, "outcome": "failed_stringing", "lesson": "TPU strung badly; it is highly hygroscopic. Dry the spool and print slow (~25mm/s) with minimal retraction — TPU clogs with aggressive retraction.", "source": "ingested", "timestamp": "2026-05-22T09:10:00Z"}
{"job_id": "ingest-004", "material": "PETG", "geometry_type": "stringing", "env_temp": 26.0, "env_humidity": 65.0, "outcome": "failed_stringing", "lesson": "PETG strings heavily in humid conditions. Dry filament at 65C for 4+ hours, then lower nozzle temp 5-10C and increase retraction to 5-6mm. Wet PETG is the #1 cause of stringing.", "source": "ingested", "timestamp": "2026-06-12T12:00:00Z"}
{"job_id": "ingest-005", "material": "PETG", "geometry_type": "bridge", "env_temp": 24.0, "env_humidity": 44.0, "outcome": "success", "lesson": "PETG bridges cleanly with fan at 80%, nozzle 240C, and retraction at 5mm. PETG likes more cooling than people think — just not on the first layer.", "source": "ingested", "timestamp": "2026-06-12T12:05:00Z"}
{"job_id": "ingest-006", "material": "PLA", "geometry_type": "overhang", "env_temp": 31.0, "env_humidity": 40.0, "outcome": "failed_sag", "lesson": "PLA overhangs sag in a hot room (31C ambient). Max fan (100%) and lower nozzle to 200C rescued the next print. PLA needs aggressive cooling when ambient is above 28C.", "source": "ingested", "timestamp": "2026-06-12T12:10:00Z"}
{"job_id": "ingest-007", "material": "PLA", "geometry_type": "vase", "env_temp": 21.0, "env_humidity": 40.0, "outcome": "success", "lesson": "PLA vase mode at 205C/60C bed with 100% fan produced a clean spiral. PLA is forgiving in cool, dry rooms — the baseline material for vase-mode prints.", "source": "ingested", "timestamp": "2026-06-12T12:15:00Z"}
{"job_id": "ingest-008", "material": "ABS", "geometry_type": "overhang", "env_temp": 25.0, "env_humidity": 42.0, "outcome": "failed_sag", "lesson": "ABS overhangs curled upward at 80% fan — ABS hates part cooling. Keep fan at 0-20% for ABS, rely on enclosure ambient temp instead. Fan on ABS causes layer delamination.", "source": "ingested", "timestamp": "2026-06-12T12:20:00Z"}
{"job_id": "ingest-009", "material": "TPU", "geometry_type": "stringing", "env_temp": 22.0, "env_humidity": 35.0, "outcome": "success", "lesson": "TPU printed clean with 3mm retraction at 25mm/s in a dry room. TPU's flexibility means retraction must be slow and short — fast retraction stretches the filament instead of pulling it back.", "source": "ingested", "timestamp": "2026-06-12T12:25:00Z"}
{"job_id": "ingest-010", "material": "PETG", "geometry_type": "adhesion", "env_temp": 22.0, "env_humidity": 50.0, "outcome": "success", "lesson": "PETG adhesion is strong on PEI at 80C bed — too strong on smooth PEI without release agent. Use textured PEI or glue stick as a release layer, not an adhesion aid, for PETG.", "source": "ingested", "timestamp": "2026-06-12T12:30:00Z"}
