Core Skills Analysis
Science
- Will explored material properties by selecting filament type and observing how different prints behaved during trial‑and‑error runs.
- He applied the engineering design process: defining the problem (a Halloween scepter), brainstorming, prototyping, testing, and iterating.
- Through scaling small prototypes to full size, Will practiced concepts of measurement, volume, and mass that relate to real‑world physics of 3D printing.
- Will engaged in systematic troubleshooting, documenting print failures and adjustments, which mirrors scientific inquiry and data analysis.
CAD/3D Printing
- Will developed spatial reasoning by constructing a 3‑D model of a scepter in TinkerCad, manipulating shapes, and visualizing the final object from all angles.
- He learned about geometric concepts such as symmetry, scaling, and the relationship between 2‑D sketches and 3‑D solids.
- The project introduced Will to file formats (STL), slicing software, and layer‑by‑layer additive manufacturing principles.
- By creating small prototypes before the full‑size print, Will practiced iterative design and efficient resource management.
Tips
To deepen Will’s STEM journey, have him research historical scepters and sketch a design that incorporates a simple mechanical moving part, then prototype the mechanism in TinkerCad. Next, set up a controlled experiment comparing two filament materials (e.g., PLA vs. PETG) by printing identical test pieces and measuring strength and flexibility. Finally, invite Will to present his project in a short video tutorial, explaining each design choice and the physics behind the printer’s layer deposition; this reinforces communication skills while cementing his technical understanding.
