42 3D Creative

What it does

Describe a shape — or upload a reference photo — and get a mesh ready to slice. Not a pretty render that collapses on the print bed.

42 3D Creative runs generation, auto-repair (hole filling, normal fixing, watertight check), and then tailors the output to your printer: resin supports auto-generated for Elegoo / Anycubic / Phrozen presets, FDM overhang and draft checks for filament machines. Target size in millimetres is a first-class parameter.

What's different about this API

• 01 Print-first, not render-first. Meshes are watertight and auto-repaired before export. Meshy and Tripo make you fix them post-hoc; we do it in the pipeline.
• 02 Printer profiles are baked in — select Elegoo Saturn and you get support trees tuned to that resin printer, not a generic "add supports" button.
• 03 Accepts text OR image input. Drop a photo of a part you want to replicate and the API reconstructs a printable mesh.

Example prompts

API

Single endpoint, JSON in, URL out. Standard REST — works with any HTTP client, n8n, Make, Zapier, and MCP.

# 1) Submit. Mention size, printer profile and format inside the prompt.
curl -X POST https://42rows.com/api/v1/tools/generate \
  -H "Authorization: Bearer 42r_sk_..." \
  -H "Content-Type: application/json" \
  -d '{
    "type": "3d",
    "prompt": "art-deco chess knight, 60mm tall, resin printer (Elegoo Saturn), STL"
  }'
# → { "id": "...", "slug": "art-deco-chess-knight-...", "status": "queued" }

# 2) Poll by slug until status = "completed" (typical 30–120s)
curl https://42rows.com/api/v1/tools/generations/art-deco-chess-knight-...
# → { "status": "completed", "preview_url": "https://...glb", ... }
