For your thesis survey on 3D printing and user innovation, consider crafting questions that delve into users' experiences, motivations, and challenges with 3D printing technology. Explore how users innovate and customize designs, their preferred software and hardware tools, and any barriers they face in the process.
Additionally, inquire about their involvement in online communities or maker spaces for sharing knowledge and collaborating with others. Gathering insights on user behaviors and perceptions can enrich your understanding of the intersection between 3D printing and user innovation, providing valuable data for your thesis research.
