Electronics information

At this time we offer 4 different types of electronics. So what should you choose? This page is to help you with your decision.

What do you need?
The first question to ask is what you need. If you are building a 'normal' 3D printer, chances are you don't need an advanced type of electronics. If you have specific requirements, you may want to investigate a more advanced type of electronics.

Why ReprapWorld.Com electronics?
We are determined in supplying cheap, but high quality electronics. Next to the 'main-stream' (and older) electronics as RAMPS and Sanguinololu, we also supply our own lines of electronics: Minitronics and megatronics. Everything is open-source as we believe in a community driven improvement process. If you are a reseller or manufacturer of 3D printers, you may have specific requirements regarding your electronics. Feel free to contact us for customization of electronics to fit your needs.

Product comparison
The following list is to help you compare the electronics. If you need more information, you can contact our technical support.
