3D Printing Cost API

We have HTTP API to get volume, surface area, thumbnail image, build time and bounding box.
NEW! Secure 3D View API for precious 3D meshes 
NEW! Comes with a free WordPress Plugin client !

Calculate the cost of 3D printed objects

Make one POST request : GET five calculation results. Costs you less than 1 cent. We charge 0% commission on your sales. Your shed, your price!


3D volume of the material used for making the object.

Surface Area

Account for the correct painting / finishing / casting cost.

Bounding Box

Identify the right printer bed size and the packaging size to ship that thing!

Build Time

Estimated time for 3D printing the object.

Thumbnail Images

XY, YZ and ZX projections rendered for your 3D object.

Secure 3D View

Allow buyers to interact with your precious 3D object without risking your source files!

Upload your 3D model!

Choose a 3D file (STL, 3DS, OBJ format).

Don't have a model to test ?

Use one of these:

Trouser Clip Cow Buddha Dragon

Account, Subscriptions and Service

Do you support WordPress integration?

Yes! We offer a free WordPress plugin client!
The WordPress Plugin client is available in the Github repo: wp-manifold.zip

To use it:

  1. Upload, install and activate the plugin to your WordPress
  2. Go to settings and enter your API key
  3. Use the following short-code:
    on any Page/Post to render a 3D calculations form.
  4. Test the API by uploading a 3D STL file via the form.

More example implementations:
Example client implementations in these languages are also provided for your reference:
PHP, JS, Java, Python clients in the GitHub repo

How can I monitor my API / account usage ?

Monitor the API usage via your Dashboard
You can see the following account details:

  • Balance calls
  • Plan name
  • Plan expiry date, etc

Do you have any documentation ?

Yeah, we has this Swagger-generated, interactive documentation on the API endpoints:

You can test the API by following these steps:

  1. POST request: Specify the API key > Choose a 3D STL file > Click 'Try it out!'

  2. GET request : Enter the task id > Click 'Try it out!' > See results

Can I use cURL to make API calls ?

Sure you can! Here's how:

POST the computation job:

curl -X POST \
-F "api_key=$api_key" \
-F "datafile=@$data_file" --url $base_url

GET the computation results:

curl -X GET --url "$base_url?task_id=$task_id"

Example response:

  "facet_count": {
    "UOM": "#",
    "value": 796
  "bbox": {
    "UOM": "mm",
    "value": {

  "volume": {

    "value": 4049.5959240246193

What is the Secure 3D View API ?

When an object is displayed in a web browser the source 3D model file is downloaded to the client machine. The source file can easily get stolen.

If you have a web-store for precious 3D meshes such as jewelry design, custom wearable design or industrial equipment design then this is an ideal solution for you to thwart piracy and protect your IP.

Upload your 3D model to Manifold via the /render API and get secure 3D viewable content that be displayed in the web-browser without exposing the source 3D model file.

Check out the demo to see this API in action!
