Have you ever wished that you had your own 3D printer? Are you finding the cost of purchasing your own 3D printer prohibitive? With this fantastic instructable from AlmusYang you can build your own 3D printer from scratch! Not only will you learn a lot about how 3D printing works, but you will be able to quickly build models or prototypes right from the comfort of your own home.
If you still weren’t convinced, an Arduino provides the brains for this 3D printer meaning that the project is very easily modified and adapted to your own purposes. This project is very well documented with full laser cutting templates and code samples provided. If the idea of building your own 3D printer is sparking your interest you can check out the full instructions at the following link.
Typically, a key component of a 3D printer are the stepper motors that control the precise printing movement.
