762 records in 17 areas: 238 read sources that the rules and checks cite, and 524 records catalogued from the Reference Map (open projects and design guides), not yet read. Open an area for its charts and a table you can filter.

A catalogued record is a search snippet: listed and linked, never cited until someone reads the source. Its numbers are the authors' claims and its licence is as the map states it.

Sources still wanted

  • 3D printing

    No independent strength data on print orientation or anisotropy surfaced, no Prusa or Bambu tolerance or hole tables, and nothing PETG-specific. Fictiv, Hubs, Shapeways and 3DXTech gave no guide of their own.

  • Sheet metal and laser

    No Hubs, Big Blue Saw, Komacut or Approved Sheet Metal page surfaced, and no standard-gauge chart. PEM design guidance, weldments and finishing are thin. SendCutSend and OSH Cut fix the 6061-T6 bend radius per thickness.

  • CNC machining

    No primary tolerance-cost data: seller-blog multipliers of 3x to 10x conflict, so they were left out. No free primary ASME Y14.5 primer or 6061 vs 7075 guide.

  • Moulding and casting

    No Hubs injection guide, and nothing on PA6-CF, gate sizing or casting. The Xometry break-even page is title-only. Formlabs has the only worked cost model.

  • Inserts and fasteners

    No readable PEM push-out or torque-out tables, no Ruthex datasheet or Voron docs, and nothing on press-fits into plastic hubs or adhesives on 6061 or PA6-CF.

  • PCB and electronics

    JLCPCB's own capability page never surfaced; its numbers came from third parties and conflict.

  • Motor winding

    No winding or motor-build guides were searched. Open projects here are thin and mostly unmeasured.

  • General DFM

    No real open-source printability or DFM analyser turned up. No toy-safety (UL 2054) entry and no Ashby or MatWeb values.
