- Emphasize precision and measurement in design.
- Create functional objects with practical applications.
- Introduce basic mechanics by designing objects with moving parts.
- Encourage iteration and refinement based on testing.
Overview of the Course:
- Advanced Modeling and Functional Design:
- Students create complex models with practical uses, utilizing advanced tools and precise measurements.
- Introduction to Mechanics and Moving Parts:
- They learn to design objects with basic moving components, understanding mechanical relationships.
- Printing, Testing, and Presentation:
- Emphasis on the iterative process as students print, test, refine their designs, and present their final projects to the class.
Session 1: “Exploring Advanced Shapes and Tools”
Description:
Students delve deeper into TinkerCad, exploring advanced shapes, the shape generator, and community shape libraries. They experiment with combining shapes to create more intricate designs, such as animals, vehicles, or fantasy structures.
Session 2: “Precision Modeling: Mastering Alignment and Grouping”
Description:
Students learn to use alignment and grouping tools to assemble complex models accurately. They practice by creating a detailed object like a personalized nameplate with decorative elements or a simple mechanical part.
Session 3: “Designing Functional Objects”
Description:
The focus shifts to creating objects with practical uses. Students brainstorm ideas for items that could help them in daily life, such as a desk organizer, a bookmark with a clip, or a custom keychain. They begin designing their chosen object in TinkerCad.
Session 4: “Finalizing Designs for Printing”
Description:
Students complete their functional object designs, ensuring they are ready for printing. The teacher guides them in checking for common issues like unconnected parts or excessive overhangs. They prepare their files for printing.
Session 5: “Printing Our Functional Objects”
Description:
Students watch as their designs are brought to life on the 3D printer. The teacher explains the printing process, including how the printer reads the design and builds it layer by layer. Students observe and note the time it takes and any challenges that arise.
Session 6: “Feedback and Iteration”
Description:
With their printed objects in hand, students test them to see if they function as intended. They discuss what works well and what could be improved. Based on this feedback, they return to TinkerCad to make necessary adjustments to their designs.
Session 7: “Advanced Modeling Techniques”
Description:
Students learn new TinkerCad features such as creating custom shapes using the Scribble tool, importing 2D images to turn into 3D models, and using hole shapes to create negative spaces. They apply these techniques to enhance their existing designs or start new ones.
Session 8: “Designing with Moving Parts”
Description:
Students are introduced to designing simple assemblies with moving parts, like a basic hinge or a spinning top. They learn about clearances and how to design components that fit and move together without fusing during printing.
Session 9: “Printing Complex Models”
Description:
Students finalize their advanced designs and prepare them for printing. The teacher assists with setting appropriate print settings for models with moving parts. Students print their designs, excited to see more complex creations come to life.
Session 10: “Showcase and Reflection”
Description:
Students present their projects to the class, explaining the purpose of their designs, the challenges they faced, and what they learned. They reflect on their growth in modeling skills and how they can apply these skills in future projects.
