With the 3D printing exhibition of “Tomorrow never knows” held by the National Science and Technology Museum (NSTM) in April 2015 as its subject, this case study creates an activity with the concept of maker movement. As an extension of the DIY activity of the NSTM, this study emphasizes the DIY aspects of its activity and uses 3D printing technology as a learning tool to encourage participants to combine content knowledge and practical applications. Through its planning and implementation, as well as evaluation and feedback, this study comes to the following conclusions: 1. The advantage of situated learning on the part of museums must be put into full play. It is difficult for common schools or even maker workshops to create an environment of situated learning. 2. Learning programs must be designed in line with a theme. 3. This study practices creative learning by “doing,” in which the learning experience pattern of “thinking, doing, and using” was verified through the implications of this activity. 4. Cross-disciplinary integration could be implemented to form new types of learning.
