In recent years, additive manufacturing technologies have made significant progress in terms of structural solutions, printing parameters, materials, and software support. This paper presents the process of reconstructing and optimizing a damaged and non-functional Delta 3D printer, with the goal of making it suitable for use in an educational setting. A Delta 3D printer is a type of additive manufacturing system distinguished by its unique kinematic structure, where three vertical arms are arranged in a triangular base configuration and simultaneously control the printhead's position. This design enables high-speed operation, precise movement, and fabrication of models with significant height. This configuration is particularly advantageous in educational environments, as it illustrates the diversity of 3D printer mechanisms and underlying engineering principles. Using reverse engineering methods and modern additive manufacturing technologies – FFF (Fused Filament Fabrication) and SLA (Stereolithography), damaged and worn-out components were replaced and certain technical improvements were implemented. The reconstruction involved replacing key components and improving the printer’s functionality and ease of use, making it more suitable for educational purposes. After the reconstruction, the device was successfully tested and is now capable of reliably producing functional models. The printer is operated using Marlin firmware and the Arduino.
