    • 3D printers are becoming increasingly popular. They provide a quick and affordable way to produce prototypes for subsequent evaluation. Many goods produced by 3D printing have even reached the market, because of their good quality and low price. In the beginning, only workshops or architecture studios could afford them. They are now are within the grasp of schools and hobbyists, and will shortly be part of many homes
    • The capability of building objects using a modest amount of raw material may change the paradigm under which certain goods are produced and acquired. In some cases, the emphasis will change from buying the product to buying or licensing the 3D model. In parallel to commercial activities, there are initiatives to put model files in the public domain for widespread use
    • Many space enthusiasts collect hardware models of space missions. This activity is typically limited by the number of companies offering good quality items, and is usually restricted to a bunch of famous missions. Some skilled fans also produce their own replicas. This usually requires the investment of a significant amount of time.
    • 3D modeling can be a complementary way to obtain space hardware. One strong point is the potential for collaboration. A large number of people can be involved in the development of a complex model without the need to share a common physical space. Models can be customized or grow in complexity and detail over time.

    Challenge Description:

    Create an open hardware design for the European Space Agency (ESA) that can be generated by a 3D printer. All of the open hardware designs will go into a public domain library of designs, and ESA will pick the best one to emerge from the 2013 International Space Apps Challenge.

    Functional Specifications:

    1. The model shall reproduce, in whole or partially, any aspect of an ESA space mission. Some examples are satellites, launchers, landers, rovers, space stations modules, dioramas, instruments and ground segment equipment. One particular example (by no means exclusive) will be modeling the spacecraft, service module or, payload of the Gaia mission.
    2. The objects should be solids suitable for printing. The models shall be an original creation of the participants. Any unauthorized inclusion of third-party intellectual property will be the sole responsibility of the participant.
    3. The build size should not be larger than 20x20x10 cm (7.87”x7.87”x3.94”).
    4. Monochrome and color models are accepted.
    5. An STL format version of the model is required. Additional files providing color and texture information (e.g. X3D, VRML, bitmap textures) are optional (and welcome).
    6. A single compressed file (zip, rar, tgz) will be sent by each participant. In principle, models will be sent directly to the email of the person of contact. Should another means be set up (e.g. web or ftp server), it will be announced to the participants.
    7. Models will be accepted until the challenge is over (22 April).
    8. The winner will be made public not later than 15 May.
    9. The designs will be evaluated in terms of fidelity, detail, ease of manufacturing and creativity.
    10. You are not limited to existing infrastructure. You can also generate 3D models related to future missions.
