As the development trends of 3D printing service changes many 3D printing websites nowadays largely use the model of 3D printing marketplace in order to carry out their e-commerce services Hence consumers who have no ideas about 3D printing theories are able to purchase their favored 3D printing products A brand-new e-commerce model however usually tends to pursue the advancement of technique and function but ignores the real demand of customers This study demonstrated the development of user-centered augmented reality (AR) interfaces of the 3D printing online marketplaces At first it summarized the demand categories of users by potential demand surveys Then it implemented the Kano questionnaire and its two dimensional quality model to sort out the categories of quality attributes to calculate customer satisfaction coefficients and to analyze the satiation criteria The result of the survey showed that the customer demands categorized as the "attractive requirement" include: " assembling and painting instructions " "product match-up preview" and "playful product preview" If these features can be prioritized during website design process we not only can massively enhance customers' satisfaction toward our websites but also differentiate ours from others Besides the category with the highest extent of dissatisfaction was "correct information" Others with higher extent of satisfaction were those abovementioned three features with attractive quality plus "product size and proportion preview" This study used augmented reality technique to overlay fictional 3D objects through image recognition system and visual tags upon a space in the reality It strategically targeted those customer demands within both attractive requirement and with higher extent of satisfaction then practically created an augmented reality interface for 3D printing online market and assessed its usability This study conducted an experiment which asked participants to experience both "normal interface" and "augmented reality interface" of the 3D printing online markets and then compared participants' reaction The result showed that participants gave positive reaction toward "augmented reality interface" Particularly the categories such as "product awareness" and "satisfaction" showed statistical significance Additionally this study formulated a simplified usage procedure of augmented reality which was verified to be reasonably applicable by abovementioned experiments In conclusion the augmented reality interface proves to be friendly and applicable for users
