An entire WinRT API surface dedicated to 3d printing: Windows.Graphics.Printing3D

WinRT APIs can be called by UWP apps and desktop apps

The entire Windows.Graphics.Printing3D API namespace is truly Universal for 3d printing across all devices

Streamline 3D printing experience in your app

Windows 3D Printing API

Unity Demo

Michael Scherotter

Generate a 3D Model from a Unity GameObject1. Save Model in 3D builder to .obj format2. Import .obj asset into Unity as a model3. Add model to scene as GameObject4. Add Print Behavior from GitHub Windows Samples to

a GameObject5. Set the Print.ObjectToPrint property to the imported

model6. Customize the UI and Game mechanics7. Build for Windows 10 UWP

Zoetrope Demo

Michael Scherotter

Printing Existing Models (C#)1. Create a Printing3D3MFPackage using a

IRandomAccessStreamvar uri = new Uri("ms-appx:///zoetrope.3mf");

var file = await StorageFile.GetFileFromApplicationUriAsync(uri);

using (var stream = await file OpenReadAsync()){ _package = Windows.Graphics.Printing3D.Printing3D3MFPackage.LoadAsync(stream);

// at this point _package.Thumbnail.TextureData has a thumbnail image you // can use in your app}

Printing Existing Models (C#)2. Register the Print3DTaskRequested callback that provides the 3MF package to the Print ecosystem.Print3DManager.GetForCurrentView().TaskRequested += MainPage_TaskRequested;

private async void MainPage_TaskRequested(Print3DManager sender, Print3DTaskRequestedEventArgs args) { // setup the sourceHandler    Print3DTaskSourceRequestedHandler sourceHandler = delegate (Print3DTaskSourceRequestedArgs sourceRequestedArgs)            { // Set the package

sourceRequestedArgs.SetSource(_package);            };            // Create 3d print task            args.Request.CreateTask(“Zoetrope", "Default", sourceHandler);          }

Printing Existing Models (C#)3. Invoke the ShowPrintUIAsync function// Launch the 3d print dialog await Print3DManager.ShowPrintUIAsync();

 4. Remove the Print3DTaskRequested callback when the dialog is launched// Remove the print task request after dialog is shownPrint3DManager.GetForCurrentView().TaskRequested -= MainPage_TaskRequested;

OpenJSCAD Demo

Michael Scherotter

Generate a new model via code (C#)1. Create a new Printing3DModel using

meshes and materialsvar model = new Windows.Graphics.Printing3D.Printing3DModel();

model.unit = Printing3DModelUnit.Millimeter;

var mesh = new Printing3DMesh();

// todo: load mesh with trianglesmodel.Meshes.Add(mesh);

var material = new Model3DBaseMaterialGroup(1);// todo: load materialsmodel.Material.BaseGroups.Add(material);

Generate a new model via code (C#)2. Verify the meshes and repair the model// verify that meshes are validvar verificationResult = await mesh.verifyAsync();

// Use the new model repair API to fix any issues await model.repairAsync();

_package = new Printing3D3MFPackage();

await _package.SaveModelToPackageAsync(model);

// Now print as before…
