💡 What is an all-metal hotend upgrade and why should you consider it for desktop 3D printing? An all-metal hotend lets you print at higher temperatures with better filament control, enabling high-temp materials and cleaner extrusion. - It improves heat transfer efficiency for high-temp materials - It reduces filament leakage with a solid assembly and heat break - It supports higher-temp plastics like PC and PVA for stronger, smoother prints
