Values from Bambu Lab's technical data sheets: stiffness, strength, elongation, bending, impact (X-Y and Z), heat deflection and Vicat. Each entry quotes its row of the sheet verbatim. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Automated review of Adds 239 mechanical entries across 15 Bambu Lab filaments. For the 8 filaments whose data sheets were fetched (ABS, ABS-GF, ASA Aero, ASA, ASA-CF, PA6-CF, PA6-GF, PAHT-CF. 128 entries), the quoted rows, values, ± and units match the sheet text, and the specimen conditions match the sheet's "Specimen Printing Conditions" block. The other 7 filaments (PC, PC FR, PET-CF, PETG-CF, PLA-CF, PPA-CF, PPS-CF. No problems found. The Polymaker question is not part of this PR and is not decided here. quotes have to match the source text, so the sustainability check cannot accept rows that are not quoted as printed. claude-haiku-5-5 · $0.21

🟡 The quote reads "80 ° C" with a space before C. The sheet text reads "80 °C". source_quote must be copied exactly, so remove the space. The same applies to /mechanical/1 ("78 ° C") and /mechanical/2 ("85 ° C"). (AI opinion)

No change. The review compared against the filament's data_sheet_url (an older copy on cdn.shopify.com), not this entry's source_url. The source_url sheet's PDF text reads 80 ° C, and the Sustainability sources script check passed on it. Writing 80 °C would make that quote check fail.

Quotes now keep kJ/m², full-width semicolons, commas and brackets as the PDF text reads them. Values are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

About the red The script part of the gate found no errors: all 239 quotes and values are on the live So those 7 filaments need a check by hand. 🤖 Addressed by Claude Code |

What
mechanicalentries for 15 Bambu Lab filaments, 239 values, from Bambu Lab's technical data sheets:ABS, ABS-GF, ASA, ASA Aero, ASA-CF, PC, PC FR, PA6-CF, PA6-GF, PAHT-CF, PET-CF, PETG-CF, PLA-CF, PPA-CF, PPS-CF.
Per filament: Young's modulus, tensile strength, elongation at break, bending modulus and strength (X-Y and Z), impact strength (X-Y unnotched and notched, Z unnotched), heat deflection at 0.45 and 1.8 MPa, and Vicat.
How each entry is sourced
source_quoteis the sheet's row, verbatim, as the PDF text reads (includingkJ/m²and full-width punctuation).source_urlis the sheet the values come from: Bambu Lab's currentstore.bblcdn.comlink, except PC, whose newer V3.0 sheet is on Bambu Lab's Shopify CDN (cdn.shopify.com; the store page still links V2.0).data_sheet_urlis left as is; on some filaments it points to an older copy.specimencomes from the sheet's "Specimen Printing Conditions" and its footnote: 100% infill, nozzle and bed temperature, speed, annealing. PPA-CF and PPS-CF also name the printer and the chamber temperature, and say the bars were not annealed.retrievedis 2026-11-08.Notes
direction: "unknown": the sheets give no print direction for them.Sustainability sourcescheck will warn thatstore.bblcdn.comis notbambulab.com. It is Bambu Lab's own file server, linked from their store pages, so the entries staysource_type: "primary".Polymaker: a question
I also have values from 10 Polymaker sheets. Their PDF text layer splits each table into columns (all labels first, then all values), and on some sheets "±" reads as "+_". So a row can't be quoted as it reads on the sheet and still pass the quote check. Would you accept the row as printed, with a maintainer checking it by hand (
sustainability-verified)? Or do you prefer another way? I'll send them in a separate PR once that's clear.Testing
