Photoshop has introduced the possibility of printing directly to i.materialise through Photoshop Creative Cloud. The process requires that you download the printer profile, available for free on the Photoshop website. Then, once your 3D model is ready to print, you are walked through a material selection, preview, and price estimation process. Finally, you are able to export your 3D file as an STL and transfer through Photoshop to the i.materialise site where all of your settings are in place for print. From that point, you simply upload and pay and i.materialise will take it from there. For more information, check out: http://3dprint.com/23542/photoshop-print-i-materialise/
