Introduction
In IB Design Technology (DT), ideas aren’t just written down — they’re visualized, modeled, and tested. Modeling and prototyping are essential tools for turning concepts into practical solutions. With first exams in 2027, students must understand how these processes work and how they’re assessed.
In this article, we’ll explore the role of modeling and prototyping in IB DT, their importance for both the IA and exams, and strategies to use them effectively. For detailed guidance, RevisionDojo’s IB Design Technology hub provides complete resources for this topic.
Quick Start Checklist
- Modeling = representing ideas before final design.
- Prototyping = building and testing real or scaled solutions.
- Both appear in IA projects and exam questions.
- Can include sketches, CAD, simulations, or physical models.
- RevisionDojo offers modeling and prototyping study resources for 2027.
What Is Modeling in IB DT?
Modeling is the process of representing a design idea before final production. Types include:
- Graphical models – sketches, drawings, CAD visuals.
- Physical models – scaled mock-ups, cardboard or foam models.
- Virtual models – digital simulations and animations.
Models help designers communicate ideas, test feasibility, and gather feedback.
What Is Prototyping in IB DT?
Prototyping goes a step further — it involves creating a working version of the design. Prototypes may be:
- Low-fidelity: simple, rough builds to test general concepts.
- High-fidelity: detailed, realistic versions close to the final product.
- Functional prototypes: working versions used to test usability and performance.
Why Modeling and Prototyping Matter
- Supports Creativity – Helps refine and visualize ideas.
- Reduces Risk – Identifies problems before full production.
- Engages Users – Allows for feedback at different stages.
- Links to the Design Cycle – Fits into the Develop Ideas and Create Solutions stages.
Modeling and Prototyping in Assessments
- IA: Students must show models and/or prototypes as part of the design cycle.
- Paper 2: May include questions on advantages, limitations, or applications of modeling.
- Paper 3 (HL): Case studies often involve analyzing how models and prototypes improve design outcomes.
Examples in IA Projects
- Using CAD to design a modular desk organizer.
- Building a cardboard model of sustainable packaging.
- Creating a working prototype of an ergonomic chair attachment.
- Testing a digital simulation of a portable solar charger.
Tips for Success
- Use multiple methods: Combine sketches, CAD, and prototypes for stronger documentation.
- Document clearly: Label diagrams, record testing, and explain results.
- Stay realistic: A simple prototype with strong evaluation is better than an over-ambitious one left unfinished.
- Evaluate honestly: Highlight both strengths and weaknesses of your model or prototype.

Frequently Asked Questions (FAQs)
1. Do I need a working prototype for the IA?
Not necessarily. A functional prototype is great, but simple models also demonstrate strong design thinking.
2. Can I rely only on CAD for modeling?
No — CAD is useful, but combining it with sketches or physical models creates stronger documentation.
3. How are modeling and prototyping tested in exams?
Usually through evaluation questions on benefits, limitations, and applications in real design contexts.
4. What if my prototype doesn’t work perfectly?
That’s fine. What matters most is documenting the process and reflecting on improvements.
5. Where can I find modeling and prototyping resources for IB DT?
RevisionDojo’s IB Design Technology hub has resources tailored to the 2027 syllabus.
Conclusion
Modeling and prototyping are essential tools in IB Design Technology, bridging the gap between theory and practice. They are central to the IA and appear frequently in exams. By mastering these processes, you’ll be prepared to communicate ideas, test solutions, and evaluate outcomes effectively.
With first exams in 2027, students need structured guidance. RevisionDojo already provides the best resources on modeling and prototyping in IB DT, ensuring you’re ready for success.
