Abstract: A method for supporting 3D printing includes identifying a product, searching and providing a 3D model present on a web in relation to the identified product, calculating and simulating suitability between the identified product and the searched 3D model based on information of the identified product and the searched 3D model, and transmitting the 3D model information to a 3D printer to produce the 3D model. Accordingly, the 3D printing technique may be actively utilized for DIY in various fields, business models or the like.

Abstract: Disclosed is a content management method, which includes obtaining data for a content including a plurality of point-of-interest (POI) and a plurality of POI documents associated with each of the plurality of POIs, obtaining at least one level-of-detail (LOD) information which allows the content to be displayed according to an interest of the user, and determining a display format for the content based on the LOD information. Here, the LOD information may include information for the interest level of the user with regard to the content, and the interest level may be independent from a scale level of a map at which the content is displayed.
