3D printing drone farm monitoring system broke out in the agricultural revolution

3D printers are like magic, transforming your favorite images into real-life creations. With just a thought, anything can become a reality. That’s why more and more designers, engineers, and makers are turning to 3D printing to explore the beauty of creativity. For Quesney Nevarez, an electrical engineering student from Mexico, this amazing world has only just begun. Nevarez, 22, grew up on her family's farm in Ciudad Obregón. This summer, she developed a 3D-printed drone design while participating in a program in Ottawa, Canada. The drone is designed to help farmers monitor their crops from the air. Although this technology is becoming more advanced and reliable, it remains costly—something her family can’t afford right now. Inspired by this challenge, she decided to create a more affordable crop monitoring system for her family. Her drone uses off-the-shelf electronics, 3D-printed parts, and open-source software, making it both practical and cost-effective. To accurately track crop growth, the drone flies over the farm at low altitudes, capturing images that show how plants absorb sunlight and their photosynthesis levels using near-infrared technology. This data helps farmers optimize water and fertilizer use or combine it with other tools to assess crop health more effectively. “This can help small farmers like my family ensure their crops are healthy,” she explained. “Currently, this technology is really expensive. We’re trying to make it as affordable as possible so every small farmer can have access to a drone monitoring system.” Nevarez was selected for the Globalink Internship Program at Carleton University in Ottawa, where she spent three months working on improving existing projects or developing new ones. At her school in Mexico, resources are limited—finding a 3D printer is already a challenge. But in Ottawa, she had access to multiple 3D printers, which made a big difference in her work. In her project, she contributed significantly, while others on her team explored new applications for driverless technology, including low-cost crop monitoring systems. “She has a strong background and experience from her family's farm, and this project brings technology to small farmers both locally and globally. It’s a perfect fit,” said Jeremy Laliberté, an associate professor of mechanical and aerospace engineering who led the program. For Nevarez, this was her first time working with drones. Yet, she managed to develop a low-cost, open-source solution that not only benefits her family but also has the potential to improve the lives of thousands of farmers around the world.
