3D Scanning

This week, we explored 3D scanning and printing techniques. For the 3D scanning, I used a Creality Ferret for the first time. This tool can achieve high-resolution scans. Personally, I am more excited about technologies to create 3D models from natural language like Hunyuan3D-2, which you can test out here: Hunyuan3D-2.

Group Assignment: Characterizing Printer

These types of test prints are readily available online and allow the user to figure out the printing capabilities of their machine. As can be seen, there are quality differences among the two printers. However, given the recent controversies on proprietary software by Bamboo, it is unclear which system to use.

Project Part

For my personal project, I designed and 3D printed an attachment piece connecting the motor to the fuselage. The inner hole features a curved profile for smooth cable threading that would be difficult or impractical to create using conventional subtractive methods, like drilling or milling. This geometry highlights the advantage of 3D printing, as it allows for intricate internal structures that cannot be easily achieved through traditional machining.
