Wanhao Duplicator i3 printer Overview

What is the Printer like physically?

The Wanhao Duplicator i3 printer is molded after the 3D printer open design. As a result, you won’t struggle with creating large structures on it.

Aside from the open design facilitating the printing of large models, the build volume makes it easier to print any model of your choice. The manufacturer created this printer with powder-coated steel, which naturally prolongs its lifespan.

There’s nothing special about the design of this printer as it looks basic. Clearly, the manufacturers didn’t intend to compete in the aesthetics field. Nevertheless, the printer is functional.

Another design feature is that the extruder and the base were not designed to depend on each other. So, when in use, you’ll notice the extruder and base move independently.

How is the Wanhao 3D printer used?

The setup of the Wanhao 3D printer is one of the reasons I’m so thrilled about it. The printer arrives pre-assembled. Simply throw the parts into themselves to assemble them.

There’s no need to solder or go through any lengthy setup phase to start operating your 3D printer. The only downside to this printer is that if the pre-assembled parts crack or there are some loose screws, it’ll be challenging to set it up.

So, when you get your printer, inspect the parts to be sure there are no loose/ missing screws or broken parts. If there’s an issue with the printer, you should return it instantly. Otherwise, you won’t be able to use it.

Every pre-assembled part is crucial to the setup. The best part is that it takes an hour to set up this printer.

There are two ways to interact with the Wanhao Duplicator i3 printer. The first is through dedicated software installed on your computer; the second is through the gcode-based microcontroller attached to its side.

Thanks to its degree of stability, this printer is your best bet if you need to go on a printing spree for extended durations. The only downside to the Wanhao duplicator is the unstable temperature- it fluctuates when you’re printing a model.

Furthermore, the Wanhao i3 printer operates with 110V and 220V inputs. If your outlet voltage is lesser or higher than the printer’s, you’ll need a step-up or step-down converter to use this printer.

Wanhao i3 Printer Features and Functions

In this section, we’ll take another bold step to clear your doubts and confusion about this printer.

Printing Quality

One of the exceptional qualities of this printer is its printing precision. Every object you print with the Wanhao duplicator looks like a near-perfect imitation of the original model.

I printed some objects with this printer, and I couldn’t believe how many details it produced. For a budget printer, I was impressed by it. But of course, what do you expect from a printer with 100-400 printing resolution and 12 microns XY precision? Nothing short of perfection, of course.

I noticed with this printer how it works with different filaments. While I got the best result with PLA and some nylon filaments, the result with ABS was terrible. Another thing I noticed with this printer is that it is sensitive.

A little dust, dirt, or liquid is enough to mess up the printing accuracy you’ll get. So, what I did to control its sensitivity was to only use it in a temperature-controlled room with a dry atmosphere.

Operation Performance

Before judging this printer, you should remember that it’s a budget printer. So, performance is not 100%. There are some good sides to it as much as bad sides. For starters, the print-bed heats up fast enough for its capacity.

In other words, you might need to wait a while for the print bed to heat- the wait time is a couple of seconds. But it has no heating issue as the print-bed uniformly heats up.

When choosing the right filament to work with, avoid filaments that require the bed to be pre-heated before use. Otherwise, it would be an epic fail. I had to upgrade the printer to print successfully with other filament types.


Another thing you should take note of when printing with this printer is the fan noise. It is loud and can be relatively distracting. However, it’s a feature you can ignore. For me, the noise wasn’t disturbing.

Software Compatibility

When it comes to the slicer, the i3 is not selective- it is compatible and supports any slicer you’d like to use. Some of the slicers you can use with your Wanhao Duplicator i3 are Slic3r, Repetier, Cura and Simplify3D. Simply connect your printer to your laptop with the cable to log into the software entirely.


In the world of 3D printing, community means “support.” It’s best to opt for 3D printers with an active online community.

While the manufacturers would provide offline support, the best kind of support comes from an online community filled with people going through similar problems as you.

Thankfully, the Wanhao Duplicator i3 has a fully active and functional online community of end-users. These End-users have gone through most of the issues they could encounter with this 3D printer.

As a result, they flood the online community with troubleshooting videos and articles and are ready to respond to concerns you might have about the printer. You can locate some of these online communities on Reddit and Facebook.

There’s also a Google community. These communities stand in as unofficial customer care to end-users. Finding replacement parts for your printer won’t be a hassle, too. You’ll also find printable models you can try on your own.


  • Is Wanhao i3 an MK10?

Yes, the Wanhao Duplicator i3 is a MK 10, and that’s because it uses an MK10 single extruder.

  • How do I update my Wanhao i3 firmware?

Since the 3D printer is open source, you can download firmware upgrades from a reliable developer within the online community. Connect the 3D printer with your laptop using the cable accompanying the printer.

Then, launch the Wanhao software. Tap on the menu and on “printer control.” You’ll see the option to “update the firmware.” Click on it and follow the instruction to update your firmware.

  • Can 3D printers copy themselves?

No, a 3D printer can’t copy itself. You’ll need a 3D scanner to copy or scan the object you want to print. Then, you can process it on your 3D printer.

Final Verdict

The Wanhao 3D printer is a budget printer whose performance surpasses other budget printers in its category. Although it’s not perfect, this printer has impressive features.

Through this detailed Wanhao Duplicator i3 review, you can tell that it is perfect for beginners. Experts can also use it as their secondary printer in its default state. But with crucial upgrades, even an expert would fall in love with its performance.
