Elegoo-Obico Plate Analysis API

The APIs documented on this page are designed for Elegoo partners to analyze 3D printing plates using Obico's AI-powered plate analysis system. This system uses advanced AI models to analyze 3D models based on isometric images and provide detailed model analysis along with recommended printing strategies.

Authentication

Authentication is performed using user credentials passed as request parameters:

• elegoo_user_id: The Elegoo user identifier registered in the system
• access_token: The access token associated with the user

These credentials can be included either in the POST request body (JSON) or as query parameters.

tipp

Use the Elegoo-Obico User Access Token API to manage user credentials before using the plate analysis API.

Language Support

API responses can be returned in different languages using the lang query parameter. See the Elegoo-Obico Language Support documentation for details on supported languages and usage.

Example:

POST /ent/partners/api/elegoo/plate_analysis/?lang=zh-CN

hinweis

The language body parameter (documented below) is deprecated. Please use the lang query parameter instead.

Response

Status code: 201

API request was processed successfully.

Body

{
  "message": {
    "role": "assistant",
    "content": "This appears to be an **octopus head model** with intricate tentacle details. The design features multiple overhangs that will require support structures.

    • Model identification and description
    • Intended use analysis
    • Geometric features and printability considerations
    • Uses bold text for key features
    • Ends with a question inviting user confirmation
  • suggested_printing_method: A recommended printing strategy focusing on technical aspects such as support type (normal or tree), brim/raft recommendations, and overall approach. Does not include specific slicer settings or orientation.
• credit_resp: Object or null. The response from the Elegoo credits API. Contains the result of the credit deduction operation.

Usage Example

curl -X POST "https://elegoo-app.obico.io/ent/partners/api/elegoo/plate_analysis/?lang=zh-CN" \
  -H "Content-Type: application/json" \
  -d '{
    "elegoo_user_id": "ELEGOO_USER_001",
    "access_token": "your_access_token_here",
    "chat_id": "chat_session_123",
    "images": ["data:image/jpeg;base64,/9j/4AAQSkZJRg..."],
    "plates": [{
      "model_objects": [{
        "extruder_id": 1,
        "id": "52",
        "name": "Octopus_Head_v6.stl"
      }]
    }]
  }'

Image Format

The images parameter should be an array of base64-encoded image strings. Images should be isometric views of the 3D model positioned on the print bed (indicated by grid lines). Multiple images can be provided for more comprehensive analysis.

tipp

Make sure to register your user credentials using the Elegoo-Obico User Access Token API before calling the plate analysis API.

warnung

The model must already be positioned on the print bed in the images. The analysis assumes the model is ready for slicing and focuses on printing strategy rather than orientation.
