Items may be packaged for shipping or storage using additive manufacturing techniques, also known as three dimensional (3-D) printing. Packages made by such processes may be referred to as 3-D printed packages and may include packing material printed at least partially around the item(s) and/or an outer cover printed about at least a portion of an exterior of the packing material and/or the item(s). A packaging system may include a 3-D printer and a computing device communicatively coupled to the 3-D printer. The computing device may obtain a packaging model describing a package for one or more items. A print module of the computing device may include instructions to print the package at least partially about the item(s) according to the packaging model.
