Adding detail and smoothing yields great, re-cast-able results. Pepakura can also be used as a base for molded armor- it provides a good base of the basic shapes to work from. And if it does, it can cost around $500USD to achieve the level of detail inherent in most molded armor.
While Pep is good for starting armorers, it rarely ends up high quality. Pepakura accepts a range of 3D file extensions, and can save files in its native extension (.pdo). Using 3 dimensional data, Pepakura allows the model to be unfolded to a flat template to be cut, folded, and glued together. Pepakura (often referred to as 'Pep') is a program that creates buildable papercraft models.
