Throughout the DIMAP - 3D Marketplace project, our primary challenge was to establish a seamless connection between makers, modelers, and customers, while promoting local, social, and ecological consumption. To address this, extensive research was conducted to understand the needs and expectations of each stakeholder group. Employing design thinking principles, I developed wireframes and prototypes aimed at facilitating efficient interactions and transactions within the marketplace. Collaborating closely with developers, we ensured that the designs not only reflected DIMAP's core values but also provided a user-friendly experience across devices. Through iterative testing and feedback loops, we iteratively refined the platform, resulting in a marketplace that fosters collaboration, sustainability, and community engagement.
