Dual Extrusion, A 3D Printing Game Changer

The days of single extrusion limitations are over. With dual extrusion 3D printers, you can use multiple filaments or even print multiple objects at the same time! With dual extrusion, not much changes in the 3D printing process other than that the printer can identify when to automatically switch to a different filament. If you want to learn more about dual extrusion, what it means, and how to successfully do it yourself, read on!

There is more than just one way to print with multiple filaments, but some are more practical than others. It is possible to print with multiple filaments using a single extruder. This manual process will require you to pause the machine during the operation to switch out the spool. This is a bit of a risky play, as it is possible that the new filament is not able to stick to the previous one and you may ruin the final product.

But have no fear, there are other options. There are 3D printers that actual melt together different filaments so that they can properly extrude, thus making it possible to print in different colors and even create blending effects. The downside here is that it will require a specific 3D printer, so if you don’t already have it, you’ll have to purchase one.

The third and final option is using a 3D printer that has dual hot end extrusion. This is also a specific type of printer you would have to purchase. Dual hot end extrusion means there are two separate nozzles that can each print 2 separate filaments. If you aren’t interested in a dual hot end extrusion 3D printer for that reason, another awesome perk is that you can simultaneously print both the object and the support structure. Therefore, this option supports both time optimization and multicolor effects.
