About Wanhao

Wanhao is a Chinese company that began its 3D printing journey in early 2011 as a small group of additive manufacturing enthusiasts. In fact, they had to save up and invest all of their pocket money in order to buy MakerBot Thing-O-Matic and study how it works. After conducting thorough research, they built their own 3D printer, and that’s how the Duplicator 1 came to life. The company’s presence on a local market was quite strong and its products demandable, allowing them to enter the global additive manufacturing market just 6 months after entering the Chinese market.  Nowadays, the Wanhao is one of the largest and well-known international Chinese 3D printer manufacturers that counts more than 20 powerful yet affordable 3D printers in its lineup.

Wanhao GR2 Overview

The Wanhao GR2 is a fully enclosed desktop FDM 3D printer that offers a handful of essential features that make for a smooth 3D printing experience. It is an upgraded iteration of the renowned Duplicator 6 Plus (D6 Plus) with an above-average build volume, sturdy all-metal frame, touch screen display, and a built-in camera to always stay on top of the printing process. The GR2 is a classic Cartesian-style 3D printer that comes factory assembled and offers assisted bed leveling, allowing you to start building three-dimensional models in a matter of mere minutes and making the device a perfect choice for inexperienced makers and hobbyists.

Its enclosed frame makes printing a safer activity and guarantees even heat distribution with a vastly improved layer adhesion. The Wanhao GR2 features a maximum build volume of 200 x 200 x 175 mm (8 x 8 x 7 in), allowing you to build a single large model or several medium-sized ones. It can print at a minimum layer thickness of 100 microns, which is typical for an FDM 3D printer. Compared to its predecessor, the GR2 is a slightly larger 3D printing workhorse that comes at 460 x 440 x 550 mm (18 x 17 x 21.5 in) and weighs just 14 kg (31 lb), making it a perfect fit at almost any desk. The GR2 has a 2 mm-thick steel frame that provides the utmost degree of reliability during printing. Besides, its sleek design and stylish dark gray color make it a nice addition to any workshop or office.

The Wanhao GR2 has been equipped with an all-metal MK11 extruder that can heat up to 260℃, making it compatible with PLA, PVA, PEVA, ABS, and other high-temperature plastics. Moreover, the new extruder offers an improved filament feeding system that prevents clogging and other issues. Unlike its MK10 counterpart, the MK11 comes with two feed gears instead of one and features a powerful cooling fan.

The Wanhao GR2 is equipped with a built-in multifunctional color touch screen that can also be operated with a sensitive stylus. The screen features silicone contact to prevent the appearance of various marks and stains that can for example be caused by touching the screen with greasy fingertips. Besides, it offers intuitive logic behind menu options and makes for an effortless, one-click experience, which is ideal for entry-level makers.

Another great addition is a high-resolution (2K HD) camera that allows you to easily monitor your print job and control the printing process remotely. Along with a plethora of connectivity options that include standard SD card and USB connection, there’s also an option to control the device, upload digital models, and view the print status in real-time by using Wi-Fi or Ethernet connection, making the GR2 an easily accessible and really responsive 3D printer.

Additionally, the device has been equipped with an advanced carbon air filter that will eliminate potentially dangerous particles and remove the smell of melting plastic in case of printing with ABS-like materials.
