Wanhao i3 Interface Keypin

Wanhao i3 Interface Keypin

Wanhao have been supplying 3D Printers internationally since as early as 2012, and have rapidly garnered a world-renowned reputation for quality machines, parts and components. After originally banding together as a group of friends and purchasing a Makerbot Thing-O-Matic, they created their own “Duplicator 1” 3D Printer, which was essentially a replica of the Thing-O-Matic, with slight modifications and alterations to make it better suit typical users.

Wanhao’s strengths have always stemmed from the fact that they are both 3D Makers and 3D Printer Manufacturers, which allows them to understand the needs of the end user when developing new models or upgrades. It is the same reason why they always make sure to stock spares of all of the different parts and components, because they believe that you should never have to buy an entirely new printer if one part breaks, and should instead be able to simply replace whichever part is broken.

There are few 3D Printing manufacturers with as much experience and reputation as Wanhao, which is why we have chosen them as one of our top suppliers here at DIYElectronics. Not only do they continue to bring out exciting new models and upgrades for existing models, but they also align with our own company culture and values by proactively supplying all of the spare parts that customers might need – so that you, as an end user, never have to source spares or alternatives if you have problems with faulty or broken parts throughout the lifespan of your 3D Printer.
