Based on your query, it seems like you're interested in 3D printing technology for educational purposes. Unfortunately, none of the products listed - hilink, DreamStudio, and Miro - directly support 3D printing.
However, DreamStudio could potentially be used in a 3D printing context. It allows users to generate images from text prompts, which could be used to visualize concepts before they are 3D printed. For instance, if you're teaching a lesson on ancient civilizations, you could use DreamStudio to generate images of artifacts or architecture from that time period. These images could then serve as a reference for 3D printing models of these objects.
Please provide more details about your specific needs so I can recommend the most suitable EdTech tools for you.
