This Wanhao D7 LCD Driver Board/Control Board is stocked as a replacement part for Wanhao D7 DLP Printer, and is responsible for interfacing with the D7 Motherboard and creating filters within the UV DLP printing process. Similar to a graphics card, this control board receives information from the motherboard which tells it what to display on the D7 LCD Display.

These displayed images then act as filters for UV light, allowing the light to reach some parts of the reservoir while filtering it from reaching other areas. Each image that it displays then acts as a filter for each layer during the print, and as the build platform is lifted from the reservoir, the resin is hardened layer by layer – eventually resulting in a clean, neat and accurate resin print.


Typical Applications for the Wanhao D7 LCD Driver Board/Control Board:

Despite being one of the most complex components on the entire machine, the Wanhao D7 LCD Driver Board/Control Board is surprisingly simple and easy to replace, as you essentially just need to take out the old one and install the new one in the same place with the same connections. As such, steps to replacing and installing a new board are as follows.

To start, you need to remove the outer casing that covers all of the bare electronics, and make enough space for you to work without damaging nearby components. This entails the removing of cables and the LCD ribbon strip that connects into the board, as well as undoing the screws that hold it firmly in place. Remember where all of these cables are meant to go, as well as the orientation of the board, as installing the new board will present some difficulties if it is installed upside down or on its side.

The next step is to simply affix the new board in the same place, in the same orientation so that the cables will reach without hassle, and then tighten the screws to hold it in place. Then, insert the cables and ribbon strip back into the same sockets as they were on the previous board. Finally, put all of the covers of the machine back on to keep the inside sealed from UV light leaks.

This process should take no longer than 30 minutes to an hour, and is made even simpler with a few easy-to-find instructional videos available on YouTube.

Wanhao D7 LCD Driver Board/Control Board

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.
