Systems, methods, and devices of the various embodiments enable advertisements (e.g., promotions, signs, logos, samples, etc.) to be part of the 3-D printing process. In an embodiment, advertisements (i.e., “ads”), such as partial product samples, may be 3-D printed prior to 3-D printing a purchased 3-D printable good. In another embodiment, ads may be 3-D printed on a 3-D printable good itself (e.g., embossed, impressed, as a tag, etc.). In a further embodiment, users may select the ads to be 3-D printed on their goods in return for compensation from advertisers.
