EasyThreed K9: The value of an AliExpress FDM 3D printer at €72

The EasyThreed K9’s hot end is actually pretty nifty. (Credit: [Thomas Sanladerer])Recently, [Thomas Sanladerer] bought an EasyThreed K9 on AliExpress for only €72 and got an FDM printer with a build volume of 10 x 10 x 10 cm. The build plate is unheated, with an optional upgrade, and there is no display to interact with the device: just a large multi-function play button and five smaller buttons that guide the printhead to preset positions above the build plate to enable leveling the building plate using the buttons on each corner. There is also a “Home” button on the back for referencing the print head, which largely completes the user interface. Since the printer comes in a rather small box, the first step is to assemble the parts into something that resembles a 3D printer.

What follows is a mixture of amazement and horror at the same time, because the quality of the plastic workmanship is anything but convincing, while at the same time the independence of each of the three axes of the cantilever design makes assembly very easy. The printhead features a convenient flip cover for easy access to the hot end, making optimal use of the powerless 24-watt power supply for the entire printer. A cooling fan with air duct even provides partial cooling, making this printhead a candidate for the “cheap but not bad” category. You can watch his full video review below.
