Our new Samsung S4 blank cases can be 3D printed (all outer surfaces) with a 3D sublimation vacuum heat press.
3D printing is the process of using a vacuum press to apply the required heat and pressure to all surfaces, not just the flat top surface.
We also supply 3D blank cases for the iPhone 4/4s, iPhone 5, iPad 2/3, the Samsung Galaxy S3, and the HTC One X.
