Material database: values to correct in the Manager admin

[BenGlut]

Checklist of values to correct in the material database, by hand in TigerTag Manager's admin interface. Tick each box once it is changed.

Why it matters. When a chip does not carry its own values, Tiger Studio shows the database's recommended nozzle, bed and drying values, and its density, in the spool's print panel (renderer/inventory.js, "from the chip's own temps when present, else the material DB's recommended values"). It also fills the spool form from them when a material is picked, and sends material_type to printers as the filament family. The wiki's materials guide is now generated from the same values, which is how these errors surfaced.

Snapshot audited: database/id_material.json in TigerTag-RFID-Guide as of 2026-09-14 (cbf7f4c), 113 entries.

1. Impossible values — fix first

• Biopolymer (id 51007) — bedTempMax is 5, below bedTempMin 45. Likely a typo for 55 (same range as PLA: 45–55).
• PEI-9085 (id 14508) — density is 0. ULTEM 9085's datasheet value is 1.34.
• PES (id 51636) — density is 0. Typical PES is ~1.37; confirm against your reference datasheet.
• PAHT (id 23080) — density is 0. Fill from the reference datasheet.

A density of 0 is worse than an empty one: it is a number, so anything computing length or volume from weight gets a nonsense result instead of "unknown".

2. Unfilled nylons carry a filled-nylon density

Every unfilled nylon is at 1.52, which is a glass- or carbon-filled value. Plain nylons are around 1.0–1.15.

• PA (id 59328) — density 1.52 → ~1.14
• PA6 (id 56666) — density 1.52 → ~1.14
• PA12 (id 55796) — density 1.52 → ~1.01–1.02
• PA11 (id 29272) — density empty → ~1.03–1.05

The filled variants also sit at exactly 1.52 — PA-CF 39944, PA-GF 30594, PA6-CF 12264, PA6-GF 1173, PA12-CF 39667, PA12-GF 2053, PAHT-CF 48815. Filled nylons do vary (roughly 1.1–1.4 depending on fibre and load), so check each against its reference datasheet rather than keeping one shared number.

3. Filled nylons with a 40–45 °C bed

Five filled nylons have a bed of 40–45 °C, while their unfilled base and PA-CF (39944) are at 100–105 °C. Same nozzle range (260–300 °C) as PA-CF, so this looks like one wrong value copied across.

• PA-GF (id 30594) — bed 40–45 °C; its base PA is 100–105 °C

• PA6-CF (id 12264) — bed 40–45 °C; its base PA6 is 100–105 °C

• PA6-GF (id 1173) — bed 40–45 °C; its base PA6 is 100–105 °C

• PA12-CF (id 39667) — bed 40–45 °C; its base PA12 is 70–90 °C

• PA12-GF (id 2053) — bed 40–45 °C; its base PA12 is 70–90 °C

• PEI-1010-CF (id 62335) — bed 80–100 °C against 150–160 °C for PEI-1010. Worth a check too.

4. material_type does not follow one convention

Tiger Studio derives the filament family it sends to printers from material_type + filled_type, so these decide what a printer is told.

• PA11-GF (id 6605) is typed PA, while PA11 and PA11-CF are PA11.
• PAHT (23080) and PAHT-GF (22652) are typed PA, while PAHT-CF (48815) is PAHT.
• PEI-1010-GF (38250) is typed PEI, while PEI-1010 and PEI-1010-CF are PEI-1010.
• PEI-9085, PEI-9085-CF, PEI-9085-GF (14508, 41134, 35377) are typed PEI, while the PEI-1010 family uses PEI-1010. Pick one convention for both grades.
• Biopolymer (51007), CoPE (12878) and Castable Filament (10478) have an empty material_type. (Castable Resin 8394 is a resin, product type 173, so an empty filament family may be intended there.)

5. To confirm — may be intentional

• PE (27635), PCL (59849), PVDF (61048) — drying is 0 °C · 0 h. If it means "no drying needed", Tiger Studio still displays 0 °C and 0 h as if they were real settings.
• Empty densities — shown as "—", which is honest but incomplete: ASA+ 54568, ASA-AF 49804, ASA-GF 35100, Biopolymer 51007, Castable Filament 10478, CoPE 12878, PA11-CF 18451, PA11-GF 6605, PAHT-GF 22652, PC-CF 20588, PC-PBT-CF 47651, PC-PBT-GF 61563, PCL 59849, PCTG-CF 53890, PCTG-GF 3481, PE-GF 1680, PEEK-CF 48469, PEEK-GF 12216, PEI-1010-CF 62335, PEI-1010-GF 38250, PEI-9085-CF 41134, PEI-9085-GF 35377, PEKK-CF 10122, PET-GF 22678, PETG-GF 34944, PETG-PTFE 5238, SBS 21307, TPU-GF 58142.
• Filled variants sharing the unfilled density — e.g. PLA-CF = PLA = 1.24, PETG-CF = PETG = 1.27, ABS-CF/GF = ABS = 1.04, PP-GF/CF = PP = 0.90. Probably a deliberate approximation; low priority.

After the corrections

1. Re-export the database to TigerTag-RFID-Guide (database/db_update.py), so id_material.json carries the new values.
2. Tell me, and the wiki's materials guide gets regenerated from the new export.
