Is a multiple extrusion 3D printer a trailblazing innovation within the 3D printing marketplace? Well, opinion varies. Several customers who had bought Fastest 3d Printers  with multi-extruder would complain that the filaments always blend their colors, while the blending of colors cause problem like color impureness and it does not give a clean break between filaments, resulting in some running or mixing of filaments when swapping during the print.

Yet, instead of complaining the downside of next to nothing, more customers praise over its functional merits rather than its shortcomings. For instance, it brings such a convenience with its all-in-one extruder with a higher efficiency. Compared to those 3D printers with one single extruder, those ones with dual or even triple extruders offer users a way more simplified and integrate process of coloring the finished models instead of adding color manually as the finished models are made. For a more precise look on it, let’s just dive in.

The Advantages of Multi-Extruder Printing (Dual Extruder as Example)

Compared to the single extruder, multi-extruder printers gain more benefits when it comes to the considerations of convenience and efficiency. Several advantages are as followed:

1. Exemption of the Annoying Filament Replacement

I think lots of 3D printer users might have always been thinking that a dual extruder printer prevails printer with only one extruder only in its printing speed. Yet what it really matters in its printing process is the replacement of filaments. It would be such a labour-intensive process if you have to pause the printing work and are about to change its filament such as (Black PLA Filament) (color or material), while the users have to pay attention and make sure that all traces of the first filament are cleared out of the extruder and nozzle without residue. That really bugs you, doesn’t it? Well, a dual extruder printer will surely free your hands without such an annoying process.

2. Unique Extruder Used for Building SUPPORTS

The other most common factor making a multi-extruder printer overwhelmingly defeat the printer with single extruder is that some models require support to hold them evenly. And in the meantime, in order to differentiate the support and the main body of the model, filaments of different materials are sometimes required. In this case, dual extruder or multi-extruder is quite promising in separating the filaments while making sure that each filament in each extruder won’t bother each other. Oh, one more thing I would love to remind you kindly, as supports are just going to be useless till the model finished, low-cost filaments are recommended to use to build.

Absolutely Mind-blowing Printer- A20M (Dual Extruder)

This device of 3D printer adopts open source GT2560 control board. In keeping the good performance of Geeetech’s portfolio of 3D printers, it aims to provide users with quality printout while providing a way amazing printing experience.

With its build volume as 255*255*255 mm³ and the classic Prusa I3 3D printers’ gantry structure, A20M makes the best of the building platform and enables you to view the printing details in 360°. Printing at the accuracy of 0.1mm, it delivers objects with smooth surface finish, clear angles and strong structure. Besides, A20M comes with filament detector and break-resuming capability, greatly enhancing your 3D printing experience.

Its well-designed extruder greatly reduces the risk of clogging or leaking. A20M extruder cover features 360°ventilation design, greatly enhancing the dissipation of heat and guaranteeing excellent printing quality.

A20M extruder motor uses a gear train of 3:1 speed ratio, amplifying input torque and improving your printing experience. Adopting the modularized design for extruder wiring, A20M makes it easy to exchange the wire.

The V-shaped wheels and rails on each axis, made from wear-resistant aluminum profile, could, in a large measure, reduce the printing noise and offer you a quiet 3D printing environment.

A20M uses silicon carbide glass as its printing platform, greatly enhancing the adhesion of first layer and making it so easy to take down the print.

In addition, A20M control board supports auto-leveling, an optional add-on. Just connect the auto-leveling sensor and adjust the related parameters. Saving the efforts of manual leveling.

Combined with 3D Wi-Fi module, A20M allows you to enjoy the convenience of cloud 3D printing solution, via which you cab get 50,000+ free 3D models, cloud slicer and remote control over your printer on EasyPrint 3D App. This self-developed App is responsive and user-friendly.
