REST / Faye APIREST API

1. Register your 3D printer

2. Upload a 3D model file (obj, stl, 3mf)

3. Repair the Mesh

4. Prepare a Tray

5. Generate a Printable file (.gcode or .png)

6. Submit a Job and start printing

3D Printing in 6 Simple Steps

• Remove Duplicate Triangles

• Remove Degenerate Faces

• Fix Incorrectly Oriented Triangles

• Close Trivial Holes

• Fix Non-Manifold Geometries

Repairing 3D Models for Printing

baseURL = "developer.api.autodesk.com"

url = baseURL + "/geom/meshes/import"

payLoad = {

"file_id": “urn:..../oss/v2/buckets/b1/objects/model.obj”,

"name": “Mesh 1” }

response = requests.post(url, json=payLoad)

⇒ taskId => meshId

Import Mesh (python)

baseURL = "developer.api.autodesk.com"

url = baseURL + "/geom/meshes/repair"

payLoad = { "id": meshId,

”all": True }

response = requests.post(url, json=payLoad)

⇒ taskId => meshId

Repair Mesh (python)

baseURL = "developer.api.autodesk.com"

url = baseURL + "/print/trays"

payLoad = {

"printer_type_id": “7FAF097F-DB2E-45DC-9395-A30210E789AA”,

"profile_id": “34F0E39A-9389-42BA-AB5A-4F2CD59C98E4”,

"mesh_ids": [ meshId1, meshId2, ..] }

response = requests.post(url, json=payLoad) ⇒ trayId

Create Tray (python)

baseURL = "developer.api.autodesk.com"

url = baseURL + "/print/trays/prepare"

payLoad = { “id": “trayId ” }

response = requests.post(url, json=payLoad) ⇒ trayId

Prepare Tray (python)

Slicing

baseURL = "developer.api.autodesk.com"

url = baseURL + "/print/trays/generatePrintable"

payLoad = { “id": “trayId ” }

response = requests.post(url, json=payLoad)

=> taskId ⇒ fileId

Generate Printable (python)

baseURL = "developer.api.autodesk.com"

url = baseURL + "/print/printers/” + printerId + "/jobs”

payLoad = { “printer_id": “printerId ”,

“id”: fileId }

response = requests.post(url, json=payLoad)

⇒ jobId

Create Print Job (python)

Printer Simulator

• You don’t need to have a real printer

• Shows how to connect the firmware to Forge

• Source code on GitHub
