The best 3D pen projects for kids include easy and safe crafts like animal figurines, cartoon characters, keychains, jewelry, name tags, and mini robots. These projects foster creativity, improve hand-eye coordination, and teach basic 3D design—all in a fun, hands-on way.
What Is a 3D Pen?
A 3D pen is a handheld device that extrudes heated plastic filament (usually PLA or ABS), allowing users to draw in three dimensions. Unlike traditional pens, 3D pens let kids build real-world, tangible objects—from toys to art to models.
Why 3D Pen Projects Are Great for Kids
- Enhances creativity through hands-on design
- Boosts STEM learning with engineering and artistic principles
- Improves motor skills and hand-eye coordination
- Screen-free fun that sparks imagination
- Teaches Patience & Focus – Precision drawing requires concentration.
Safety Tips for Using a 3D Pen with Kids
Before diving into projects, here are a few important safety guidelines:
- Always supervise children under 12.
- Use child-friendly pens with low-temperature settings.
- Choose PLA filament (biodegradable and low-fume).
- Teach proper hand placement to avoid nozzle burns.
- Work in a well-ventilated area.
Best 3D Pen Projects for Beginners (Ages 6–8)
These simple and safe projects are great for little hands and short attention spans.
🐶 1. Animal Outlines on Paper
Use templates to draw cats, dogs, or dinosaurs with a 3D pen. Start with 2D before assembling parts for a 3D figure.
🌟 2. Magic Wands
Kids can design and decorate their own wands using glitter filament and star templates.
💍 3. Colorful Rings or Bracelets
Create fun wearable crafts using a mold or by drawing loops and shapes on parchment paper.
🧸 4. Cartoon Keychains
Use stencils of cartoon characters like Pikachu, Peppa Pig, or SpongeBob to make adorable keychains.
🧲 5. Alphabet Magnets
Print each letter of the alphabet to make learning fun and tactile. Stick a magnet on the back and use on fridges or whiteboards.
Intermediate 3D Pen Projects (Ages 9–12)
Once they’re confident, kids can take on slightly more complex builds:
🧱 6. Name Tags or Desk Signs
Help your child 3D draw their name in bubble letters, then mount it on a base to use on desks or shelves.
🏰 7. Fairy Houses or Castles
Use multiple parts—walls, roofs, turrets—and glue them together. Add vines, windows, and lights!
🚗 8. Toy Cars
Build wheels and a car body, then snap them together. Bonus points for making the wheels roll!
🎄 9. Holiday Ornaments
Draw 2D holiday shapes—like snowflakes, hearts, pumpkins—then add 3D texture or hang them with string.
🍩 10. Mini Foods
Make donuts, ice cream cones, fruits, or pizzas. Great for dollhouse play or pretend picnics.
Advanced 3D Pen Projects for Older Kids (Ages 12+)
These require multi-part assembly, symmetry, and patience.
🤖 11. Miniature Robots
Use a template to design and build articulated robot figures with arms, legs, and joints.
🕷️ 12. Spider Webs or Insects
Perfect for Halloween or science class—draw thin spider webs, butterflies, or beetles with clear filament.
🧠 13. 3D Brain Model
Create a layered, cross-sectioned model of the brain—great for science fair projects.
🎮 14. Gaming Symbols or Controllers
Make iconic symbols from Minecraft, Fortnite, or Pokémon using colored filaments.
🏆 15. Mini Trophy or Award
Design a custom “Best Brother,” “Science Champ,” or “Coding Queen” trophy as a gift.

FAQs: Best 3D Pen Projects for Kids
Q1. What’s the best 3D pen for a 7-year-old?
A low-temperature, easy-to-use model like the 3Doodler Start+ is ideal for young children.
Q2. Can kids use ABS filament safely?
It’s better to use PLA filament since it has a lower melting point and emits fewer fumes.
Q3. What age is appropriate for 3D pen use?
Most manufacturers recommend 3D pens for ages 6+ with supervision.
Q4. Do 3D pen projects require a computer?
No. 3D pens are standalone tools—you only need a power source and filament.
Q5. Can you reuse old filament or scraps?
Not easily. It’s best to use new, untangled filament to ensure smooth operation.
Q6. Is a 3D pen a good educational gift?
Yes. It promotes STEM learning, creativity, and manual dexterity.
