                                                           Researchers need to communicate their findings both within Academia and towards the general
                                                           public. This requires the interpretation of scientific data to reach the intended audiences. Since the
                                                           rise of Geoinformatics, this task is often accomplished using computer based visualisations, ranging
                                                           from animated movies to immersive virtual reality environments.

                                                           3D printing enables the creation of tangible representations of scientifc data, adding

Tangible 3D printouts of scientific data volumes with FOSS - an emerging field for researchEGU 2013 [ESSI Poster #1544]

  • 1. Tangible 3D printouts of scientific data volumes with FOSS - an emerging field for research Peter Löwe¹, Jens Klump¹, Jens Wickert², Marcel Ludwig², and Alessandro Frigeri³ ¹ Centre for Geoinformation Technology, GFZ German Research Centre for Geosciences, Potsdam, Germany ² GPS/Galileo Earth Observation, GFZ German Research Centre for Geosciences, Potsdam, Germany ³ INAF-Istituto Nazionale di Astrofisica · Institute for Space Astrophysics and Planetology IAPS, Rome, Italy Contact: ploewe@gfz-potsdam.de 3D printed Handpieces for Science Communication Researchers need to communicate their findings both within Academia and towards the general public. This requires the interpretation of scientific data to reach the intended audiences. Since the rise of Geoinformatics, this task is often accomplished using computer based visualisations, ranging from animated movies to immersive virtual reality environments. 3D printing enables the creation of tangible representations of scientifc data, adding haptic perception as a channel for science communication, based on a rapid and affordable production process. Figure 2: A 3D print of the north polar cap of Mars (left) was produced based on a volume model produced by the italian Free and Open Source GIS for Scientific 3D Printing National Institute for Astrophysics (INAF) based on ground penetrating radar from the SHARAD and MARSIS sensors Figure 1: 3D print of a landscape surface (right)[Frigeri 2012]. derived from a Laserscan Digital Elevation A novel workflow based on the Free and Open Source Software (FOSS) tools GRASS GIS and Model. Paraview to convert scientific data volume into printable data formats has been developed by GFZ Potsdam. An extrusion deposition printer (RapMan) is used to create tangible scientific data printouts. Towards a Scientific 3D Application Fields Printing Process Tangible 3D printouts are used in several applications in Geography, Geology, Planetology and The production of a tangible representation from a Tsunami Simulation: scientific data set is the final step of a larger The initial motivation was quality assessment on tsunami simulation data sets in the FP7 TRIDEC process, linking the physical world and scientific project (www.tridec-online.eu). For this, 3D printouts of space time cubes of tsunami wave reasoning: The process starts with an observation spreading patterns were produced. Other applications involve high resolution land surfaces (Figure resulting in a geo-referenced data set. This data is 1), geologic layers (Figure 4) and ice deposits (Figure 2). Additional application fields are currently turned into a volume representation for the printing investigated. device, leading to the creation of a 3D printout. Figure 3: The 3D printing process for science data: Starting Finally, the new 3D specimen has to be linked to its with a scientific data set, a printable representation is derived, metadata to ensure its scientific meaning and resulting in the 3D printout. This printout must be connected to context (Figure 2). the metadata of the original data and the printing workflow. Figure 4: 3D printed stack of the underlying geology of the eastern german basin. The 3D prints depict permocarbon volcanics (red), Rotliegend sandstones (brown), permian Zechstein (blue), triassic Buntsandstein (purple), upper cretacious (green), and quaternary deposits (yellow). www.gfz-potsdam.de
