FilManager

FilManager is a desktop application built to support 3D printing enthusiasts and businesses by tracking filament usage, managing printer operations, and calculating associated costs. This project was developed as a high school graduation thesis (lucrare de atestat) by Durdeu Vlad Ioan, and it proudly earned First Place in a National Computer Science Project Competition in 2022.

🧠 Project Motivation

Owning and maintaining 3D printers involves more than just operating hardware—it requires effective tracking tools that were simply nonexistent in the software market. Commercial apps were becoming outdated and lacked the features required by modern 3D printing needs.

FilManager was born out of necessity and built by a 3D printing enthusiast, for other enthusiasts. The application supports:

• Secure user login and registration
• Email-based account recovery
• Secure database operations filtered per user
• Tools for business cost estimations

FilManager simplifies 3D printer management and represents a small revolution for anyone operating custom print services.
