Virtual Lab for Engineering Education
As part of a National Science Foundation (NSF)-funded initiative, I designed and developed an immersive Virtual Reality laboratory that transforms how students learn manufacturing and engineering fundamentals—making hands-on education accessible, safe, and scalable.
🎯 The Challenge
Traditional engineering labs face critical limitations:
- High equipment costs restrict access
- Safety concerns limit hands-on learning
- Physical space constraints cap enrollment
- Scheduling conflicts reduce practice time
💡 The Solution
We created a fully interactive VR environment using Unreal Engine, enabling students to:
- Explore complex equipment without risk
- Practice manufacturing workflows repeatedly
- Access laboratory experiences remotely
- Learn at their own pace
🏭 Virtual Lab Architecture
The VR system features three interconnected learning spaces:
1. Design Studio
| Feature | Description |
|---|---|
| 3D CAD Interaction | Manipulate parts, assemblies, and drawings in immersive 3D |
| Design Analysis | Visualize stress, thermal, and fluid simulations |
| Collaborative Review | Multi-user design review sessions |
2. Manufacturing Floor
- Additive Manufacturing — FDM, SLA, and SLS printer simulations
- Subtractive Processes — CNC milling and turning operations
- Forming & Casting — Sheet metal and injection molding workflows
3. Testing Laboratory
- Mechanical Testing — Virtual tensile, compression, and fatigue testing
- Quality Inspection — CMM and metrology equipment simulation
- Materials Characterization — Hardness and microstructure analysis
