While the primary focus of this discussion is on AR\'s impact on customer engagement, it\'s worth noting the peripheral yet potentially impactful roles of 3D modeling for 3D printing and the services of a 3D model maker for 3D printer within the shopping ecosystem. Imagine a future where customers can personalize products online using AR and then opt to have those customizations 3D-printed, either by the seller or through a third-party service. This level of personalization and on-demand creation could represent a significant evolution in the shopping experience, fostering deeper customer co-creation and brand loyalty. While not directly tied to immediate visual engagement in the browsing phase, the underlying 3D models created for AR can often be adapted for 3D printing applications, opening up exciting new avenues for customization and product interaction.
