Snapmaker is known for its multi-tool machines, but with the U1 four 3D print tool head design, it focuses on refining 3D printing with a machine that can handle four materials out of the box, fast ...

Indeed, by Hofferth's own account, the online response to the 3D-printed enclosure has been "tremendous," and the maker says he's enjoyed iterating on the design in response to feedback. Hofferth ...

Furthermore, 3D printers make it easy to work with plastic. That said, various 3D-printing processes have been available for over 20 years, yet they haven’t made great inroads into plants and shops.

Standard 3D printing simply can't reproduce the level of detail on models. The Elegoo Mars 5 is the latest and greatest, but at this price the Mars 4 is the better budget machine.

The machine’s 3D printing software “slices” the file into 2D layers, or G-code (.gcode), the language the 3D printer uses to control each axis and tool head.
