3D Printing in Classrooms: 5 Projects You Can Do Without Learning CAD
3D printing is one of the most exciting ways to bring STEM and creativity into the classroom. But let’s be honest, learning traditional CAD software can be time-consuming and intimidating, especially for younger students or teachers without a tech background.
Thankfully, you no longer need to master complex tools like Fusion 360 or Tinkercad to get started. With AI-powered platforms like PrintPal's Image-to-CAD, students can sketch ideas or generate concepts and instantly turn them into 3D printable files.
Here are five engaging 3D printing projects your class can do without learning CAD:
1. 🖐 Personalized Keychains from Sketches
Let each student design their own keychain by drawing their initials, a symbol, or a favorite object.
How:
- Students sketch their design on paper
- Upload the drawing to PrintPal’s Image-to-CAD tool
- Download the STL and print in their chosen color
Why it works:
This is a great first project, and it’s personal, creative, and quick to print.
2. 🏫 Build a Miniature Landmark
In a geography or history class, students can recreate famous landmarks from around the world.
How:
- Use ChatGPT or Midjourney to generate a simple image of a landmark (e.g. "cartoon-style Eiffel Tower")
- Upload the image to PrintPal’s Image-to-CAD generator
- Print, paint, and present!
Educational tie-in:
This reinforces lessons about world history, architecture, and geography through hands-on learning.
3. 🌿 Design a Custom Planter
In science or sustainability units, students can create a planter for growing herbs or small plants.
How:
- Prompt: "A small planter shaped like a turtle, cube, or pyramid"
- Use AI image generation (optional)
- Turn into a 3D model via PrintPal, then print and plant!
Bonus:
Have students name their planters and track plant growth over time.
4. 🧰 Create Story-Based Figurines
Use this in language arts or creative writing. Students can invent a character, sketch it, and bring it to life.
How:
- Students draw their character
- Upload to PrintPal to turn it into a basic 3D model
- Print and use in storytelling, presentations, or even stop-motion videos
Tip:
Pair this with a short writing assignment about their character’s background.
5. 🧱 Classroom Utility Challenge
Challenge students to invent a useful item for the classroom: a pencil holder, bookend, or cable organizer.
How:
- Brainstorm ideas as a group
- Draw product concepts on paper
- Generate 3D models via PrintPal and test-print them
Bonus:
Vote on the best ideas and mass-print them for classroom use.
✨ Why This Works
- ✅ No CAD required
- ✅ Projects can be done in one or two class periods
- ✅ Cross-curricular tie-ins (STEM, art, ELA, history)
- ✅ Encourages creativity and real-world problem-solving
With tools like PrintPal, 3D printing becomes an accessible, fun, and meaningful way to engage students of all ages - no advanced software needed.
