Inventra 3D
A competition for students in classes VIII - X to design 3D models that address real-world problems or improve existing systems. Participants will utilize 3D modeling software to create their design and present their solution through a video and a PowerPoint presentation.
General Guidelines
Registration Closes: 1 July 2025
Submission Deadline: 3 July 2025
Mode of Conduct: Online
Eligible Classes: VIII - X
Team Size: 2 Students
Maximum Teams Per School: 2
Video Presentation: 3-5 minutes
Rules & Regulations
Participants must design a 3D model that solves a real-world problem or improves an existing system.
A PowerPoint presentation is mandatory and must explain:
- Problem Statement
- Solution Overview
- Research Summary
- Images/Screenshots of the 3D Model
Additional slides (e.g., backstory, working demo, feasibility, cost analysis, creative vision, future scope) are allowed and encouraged, but not mandatory.
Making a video showcasing the 3D model creation process is encouraged but optional.
Any 3D modeling software may be used (e.g., TinkerCAD, Fusion 360, Blender, SolidWorks, etc.).
All submissions must be original. Plagiarism or use of pre-designed models is strictly prohibited.
Categories
