# Research Overview

### Open Research in Additive Manufacturing for Educational Toy Kits <a href="#open-research-in-additive-manufacturing-for-educational-toy-kits" id="open-research-in-additive-manufacturing-for-educational-toy-kits"></a>

by Dhamodaran KKP

#### Vision <a href="#vision" id="vision"></a>

To explore and openly share sustainable, affordable, and pedagogically rich 3D printed educational toys that empower students and teachers to engage in hands-on STEM learning aligned with the Sustainable Development Goals (SDGs 4, 9, and 12).

#### About This Project <a href="#about-this-project" id="about-this-project"></a>

This project documents the open research journey in:

* Designing 3D printed educational toy kits
* Integrating them into classroom learning (5E Constructivist Model)
* Testing materials, print settings, and student usability
* Sharing all outcomes as open educational resources (OERs)

The project is maintained by **Dhamodaran**,
