3D printing technology helps rehabilitation professionals make an order-made assistive device (AD). However, most have not learned how to use the technology for clinical practice. The study is aimed to evaluate a 3D printing technology learning program for rehabilitation professionals. Eligible participants who have a licence for physical, occupational or speech-language therapy and have not experienced learning any 3D printing technology. The learning program was conducted in accordance with Kolb's Experiential Learning Theory (Morris TH, 2020). The program was conducted over eight weeks. The outcome measure included the Japanese version of the modified Technology Acceptance Model questionnaire (TAM-J). It consists of 13 items and four scales; Perception of usefulness (28 points total), Perception of ease of use (35 points total), Attitude toward use (14 points total) and Intention to use (14 points total). Within-group analyses were performed using the Wilcoxon signed-rank test for the TAM-J between different time points.

Inclusion Criteria:

• Eligible participants who have a licence for physical, occupational or speech-language therapy

Exclusion Criteria:

• Participants who have experienced learning any 3D printing technology.
