Abstract
To obtain relief map, the national mapping agencies have used thermoforming techniques during many years. But this solution is not usable for only one map and can not provide the market of 3D map on demand. To find a solution for this problem, IGN France examined different solutions which appeared in 3D print domain. In 2014, the company Océ contacted IGN to propose a new French technology to solve this problem with the Project EIGER. The Project EIGER (www.projecteiger.com) is an innovative service for 3D print on demand which allows to obtain printing with an height until 1 cm. This new French technology for printing allow to print 2D documents (images, texts, patterns, pictures…) with additional relief. This relief is obtained with the deposit and the superimposition of liquid inks layers which create visual and tactile documents. With this technology, it is possible to simulate existing textures as wood, stone, leather or to duplicate paintings with printing. The Project EIGER can be distinguished from other 3D printing by 4 specificities: • In the opposite of existing 3D printing solutions Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS) or Stereolithography (SLA), the Project EIGER printing solution uses only liquid inks. • The colorimetric constraints in four colours (CMYK) are preserved: it is possible to use and print the same colour palette which is user in 2D printing. This specificity is an important improvement in comparison with other 3D solutions. • The Project EIGER printings are done in very high resolution: 450 dpi in horizontal axes and 1800 dpi in vertical axe. • The last specificity, very important for cartography, deals with the large format: it is possible to print on 3m2 support which includes a large part of cartographic relief printing. At this moment, the printing can be done on four different supports: aluminium, Plexiglas, and sticker and other supports are examined. The Project EIGER solution is already used in different domains: illustration and graphics (posters, visit cards), Art and Museums (works of art reproduction), education and pedagogy, decoration of house, personalisation (stickers, phone shells). This paper will present the new opportunity of this solution for cartography and will present different cartographic products that we already obtained. An example is provided in figure 1 on the French island “La Réunion” in Indian Ocean. DTM and digital map on the Island were used to obtain this 3D printing. This paper will detail the process to obtain the different data which can be printed in 3D and the web services that we will plan to develop to allow the user to print 3D map on demand.
