MorphPlay – Circle to Sphere
Project Brief: MorphPlay – Circle to Sphere Interactive Learning Kit
Introduction
Learning geometry often happens on a flat surface — students draw circles and label formulas, but rarely see how those shapes evolve in three dimensions. This project, MorphPlay, aims to change that.
Using 3D printing and Fusion 360, the idea is to transform a simple classroom concept — a circle turning into a sphere — into a tangible, playful learning experience. The goal is to let students see, touch, and interact with the transformation process, bridging the gap between abstract geometry and real-world visualization.
Project Objective
The main objective of this project is to design and develop a 3D printed educational model that demonstrates how a 2D circle generates a 3D sphere through revolution around an axis. To make the concept engaging, the model includes interactive and playful elements such as magnetic assembly, color coding, and a spinning version that visually illustrates the geometric transformation.
Specific objectives include:
Designing accurate models of 2D and 3D shapes using Fusion 360.
Creating modular and interactive components to enhance play value.
Incorporating color and motion to support visual learning.
Making the design simple, printable, and reproducible for educational use.
Concept Overview
The MorphPlay Kit is a three-stage learning model that visually and physically explains the transition from a circle (2D) to a sphere (3D):
Flat Circle (2D): A simple circular disk representing the base geometry.
Half Sphere (Intermediate): Created by revolving a semicircle around an axis, showing the halfway transformation.
Full Sphere (3D): The complete solid formed by full revolution.
To add engagement, magnets or snap-fits allow these parts to connect sequentially. Each model is color-coded and engraved with math hints like A = πr² or V = ⁴⁄₃πr³. A spinning version of the circle is also included, demonstrating the visual effect of revolution — when the flat circle spins fast enough, it appears spherical.
Educational Significance
This project goes beyond a simple model — it’s a learning experience that encourages exploration and curiosity. By interacting with the MorphPlay kit, students can:
Understand how revolution of a 2D shape creates a 3D object.
Visually compare area and volume.
Relate geometry and motion through hands-on experimentation.
Connect digital design (Fusion 360) with physical creation (3D printing).
Such experiences make abstract mathematical ideas tangible and memorable, fostering a deeper understanding of geometry and design thinking.
Design Tools and Materials
Software:
Autodesk Fusion 360 – for 3D modeling, extrusion, and revolve features.
Ultimaker Cura – for slicing and preparing STL files for 3D printing.
Hardware & Materials:
FDM 3D Printer (e.g., Creality Ender, Prusa, or similar)
PLA filament – safe and easy for classroom use
Small neodymium magnets – for modular connections
Multi-color filament (Blue, Green, Red) – to represent transformation stages
Expected Outcome
A 3D printed interactive geometry kit showing circle-to-sphere transformation.
Three separate models representing the different stages of revolution.
A spinning demonstration model to visualize motion-based transformation.
Printable lesson handout and QR-based quiz for extended learning.
Open-source design documentation and STL files available via GitBook.
Broader Impact
MorphPlay integrates geometry, design, and play — encouraging students to think creatively and analytically at the same time. The project can easily be expanded to other shape transformations, such as square to cube or triangle to cone, forming a complete series of interactive learning aids. By using Fusion 360 and 3D printing, this project also introduces students to modern digital fabrication tools, preparing them for future STEM learning.
