Big DIY 3D printer 2

Big Maker 3D Printer 2 This 3D printer is a major upgrade of the Big Maker 3D Printer. I decided to create a new version because I made so many changes. The goal of this printer is to make it with materials you already have, keeping it affordable. A 3D printer has X, Y, and Z axes. This model is an X and Y axis that can be raised as high as desired, making it larger on the Z axis. In my example, I made a Z axis from extruded aluminum lengths (30x33mm) and 608Z bearings I had. I included files for the Z axis if you want to make it this way. The X and Y axes can also be made as long as desired. Length is determined by the length of 10mm rods used. My rods are 1000mm long, so the maximum length of X and Y are 835mm by 710mm. My Z height is 680mm at the moment because the aluminum lengths I have are not longer. If they were, I would make the Z axis 2 meters. However, a big printer has its issues. Printing large objects means it will take a lot of time, so you want to speed it up. But then vibrations and noise will be much stronger. Also, the longer your rods are, the more vibrations you will get. To reduce these effects, I made this lighter X axis and X car setup. Now the X car can move faster with less vibration. The controller and firmware are still the same as with Big Maker 3D Printer.
