While additive manufacturing offers unprecedented opportunities, it is still complex, expensive and not always reliable. Until now, proprietary technologies and fragmented processes have limited innovation and adoption in 3D printing. To address these challenges, Autodesk developed Spark, the first open professional 3D printing platform.Spark provides extensible APIs for each stage of the 3D printing workflow. These enable businesses to quickly add 3D printing functionality to applications. With Spark, any application can prepare, optimize and deliver 3D models for any 3D printer or service bureau.
