This prototype was conceived for the final project of my Ideation & Prototyping course during Summer 2021. The assignment was a ‘Future Casting Project,’ in which, working in small groups, we envisioned a potential future world and an invention we would construct for it. Inspired by post-apocalyptic literature, media, and video games — specifically Death Stranding — my group of three created a future in which drastic climate change creates weather patterns of acid rain that rapidly degrades anything it comes into contact with. As such, it becomes a necessity for households to possess futuristic 3D-printing technology to analyze faults in their wares and rapidly repair them. Inspired by Subnatica’s handheld scanning devices, we conceptualized a handheld 3D printer with a scanner integrated into the printer head. Thus, the user could easily have the device find the points of repair and guide the user accordingly to a full repair.
