3D printing has revolutionized manufacturing, allowing creators to produce complex parts and prototypes with ease. As the technology advances, so do the components and materials used to build and enhance 3D printers. One critical component is the extruder, which feeds filament to the hot end to create the printed object. A popular choice for building robust and precise extruders is the 3030 aluminum extrusion. This article explores the benefits, applications, and design considerations of using 3030 aluminum extrusion in 3D printer magnetic extruders.
