Adobe has unveiled a major update to Photoshop CC (Creative Cloud) with the hope that a "radically simplified 3D printing process" will make their software the "go-to tool for anyone who wants to print a 3D model." Their new software allows for designers to create a model from scratch or refine an existing design leading to perfect print ready 3D models. Since one of the most common problems with 3D printing is the human errors in virtual modeling, Photoshop includes automatic mesh repair and will insert a support structure if necessary to ensure that the model will print reliably and without faults.
