Using a secondary dissolvable material, you can create removable supports for those tricky overhangs and bridges that single extruder 3D printers can’t handle. It’s also a useful technique for fabricating objects with complex geometry. Therefore, it becomes possible to print off objects in two colors or two materials (or both). What’s a dual extruder 3D printer? It’s an evolution of the Fused Filament Fabrication (FFF) technology, where instead of one hot-end extruding molten thermoplastic filament, it has two hot-ends with two separate spools of filament. But what if you wanted to print something in more than one material? This is where a dual extruder 3D printer comes in handy. Making stuff in a single material, for example, is pretty much the standard option for most 3D printers and projects. Need an advanced and colorful challenge? Here are 35 free dual extrusion models specially designed for your dual extruder 3D printer.ģD printing is a fun hobby, and one that you can make as simple or as complicated as you like.
