Many of our customers are hobbyists who use our components as part of their maker or DIY projects and we’ve worked with a number of customers shopping for stepper motors and other motion control supplies for building a 3D printer. It occurred to us that a great way to gain insight into our customers’ needs and challenges would be by building a 3D printer ourselves!
We began by comparing and evaluating various models on RepRap, which is a Wikipedia of sorts for open source 3D printers. There are many models of DIY printers with many iterations of each model, but we finally settled on the Mendel90, which is a slight modification of the Prusa Mendel. We liked the clean look and versatility of the printer, so we ordered a kit from the printer’s creator, Nophead. The kit didn’t include a power supply, so we used our 600W 12V power supply.
Here is an overview of the build in pictures:
It took us about a week, working a few hours time, to build the 3D printer and it certainly isn’t a simple process. Don’t expect to breeze through a project like this. Although there are many components and sub-components, with the proper tools and enough determination most people can build one of the 3D printers on RepRap.
The post-assembly process was equally challenging. It takes a bit of time to get familiar with the software used to convert a generic sketch .stl file to .gcode that the printer can understand.
As previously mentioned there are dozens of models of DIY 3D printers for you to choose from. That being said, most builds use many of the same parts, so we put together a bill of materials (BOM) for building a 3D printer. We hope you find it useful!
And, finally, here is a time lapse we filmed during one of our elephant prints.
