Duplicator I3 V2.1 - Steel Frame


The #1 ranked 3D printer is now better than ever! The Duplicator i3 V2.1 is based on the revolutionary work of reprap core developer Josef Průša (Prusa). Wanhao is proud to introduce an entry-level 3D printer designed for customers who want to begin 3D printing without having to build a kit. This is a pre-assembled steel frame Prusa i3...the best-selling reprap in 3D printing!

Better features than machines 3 times the price... Among the features packed neatly into this printer are an MK10 single extruder with cooling fan, a gcode-based micro-controller, and a standard Heated Build Plate. Unlike most other Prusa offerings on the market, the Di3 V2.1 comes standard with a fan-cooled electronics housing and a custom filament holder. For the value this machine can not be beat. This printer is the ultimate reprap!

The MK10 hotend is all-metal with the exception of the industrial-grade PTFE insert and allows temps up to 260°C. Higher temperature capability allows the use of more materials and faster printing speeds.


Extra-long 45mm LM8UU bearings guide the extruder assembly for better lateral tracking. 


The Z-Axis endstop switch comes secured to a height-adjustable bracket allowing the freedom to choose between any of your favorite build plates. 


Software Freedom... 5 years of feedback has proven that users want the freedom to choose their 3D printing software based on the CAD programs they use every day. The obvious choice was to allow the Di3 V2.1 to accept open-source software in order to streamline the workflow of pro and novice users alike. Use the pre-loaded CURA Wanhao Edition or pick from the dozens of free and commercially available software packages online. Enjoy the freedom to use the most widely used file types from the best software packages on the market:

OBJ: Microsoft Visual Studio and CADRazor
STL: Thingiverse and Google Sketchup
DAE: Blender, FreeCAD, and Autodesk
AMF: Solidworks




This model is recommended for Beginners, Hobby Enthusiasts, & All-around Makers.
