2025 STEAM EXPO

PROJECT SUMMARY

I manufactured an anatomically accurate, life-sized 3D printed heart model divided in two parts to show internal structures. The project focuses on helping students visualize and better understand the human heart.

WHY?

I wanted to make anatomy more accessible and engaging through a realistic, hands-on model. I decided to present it as an educational tool, so I printed this model for my Natural Sciences project.

HOW?

I used a Flashforge Hunter resin 3D printer to print the heart model (downloaded from a free access website named Thingiverse), and I designed the stand to hold the heart in place. Removing the supports and sanding the resin figure was difficult and time-consuming. I had to go into the laboratory during recesses and rush to put on a mask to avoid breathing the toxic resin fumes. Even with a strong headache, I managed to keep working and finish the pieces. Then I hand-painted it with acrylic paint to highlight anatomical features and sealed it with three layers of varnish to protect the finish.

WHAT?

The model turned out durable and visually detailed, which made it easier to explain the parts and function of the heart. The split design helped clearly show the internal chambers and vessels.

SO WHAT?

This project shows that realistic 3D models can improve how we learn anatomy by allowing direct interaction. I also learned that combining science with art can make complex topics easier to understand.

WHAT'S NEXT?

In the future, I could make other organs in the same style or even design a full circulatory system. I would also explore adding labels or interactive elements to make the model more informative.

REFERENCES & ACKNOWLEDGMENTS

This project was inspired by my Natural Sciences project. My friend M helped me paint a small part, and I thank her for that. I completed most of the work myself, while my classmate Daiki also contributed during the original version of the project.
