Large Volume 3D Printer

Large Volume 3D Printer Specifications: Build Volume: 300x300x400mm Dimensions: X520-Y620-Z640 Design: The printer is built mainly with high-strength aluminum profiles and printed parts, showcasing an optimized lightweight design. Extruder: The extruder is a reliable MK8 model. For future upgrades, I plan to use a more efficient "Bowden" type system. Optimization Opportunities: The Y carriage with hot bed can be further improved by reducing its weight. This can be achieved by cutting the aluminum sheet that holds the hot bed and replacing it with 3mm glass. Y Carriage Engine Power: Initially, the engine power of the Y carriage was set to 1.7 A. However, I upgraded it to 2 A to enhance dynamics. Commercial Components: All commercial components except for the aluminum profiles and chrome bars were sourced from Aliexpress.
