However, most 3D modeling software is still geared towards experts and not as inclusive as the printing technology itself. At the same time, tools are usually limited in their possibilities for collaboration. Against this backdrop, we are conducting qualitative studies with children in Germany and Palestine on practices of co-constructive 3D modeling in virtual worlds. We aim to understand how children negotiate and cooperate on joint projects and how to lead non-experts playfully into 3D modeling. For this, we utilize the game Minecraft as well as the similar browser-based tool Cubeteam. In this paper, we present first results as well as design implications for co-constructive 3D modeling tools.en3d printing3d modelingMinecraftCSCWeducationKooperative Systeme und KooperationsplattformenAneignungVertrauen und MotivationEntwurf von Kollaborationsprozessen und -systemenBeobachtete Phänomene bei der Zusammenarbeit und Theorien zu deren ErklärungText/Workshop Paper
