New in box SK-1 + 7 Filament RollsLOCAL PICK UP ONLY- WE DO NOT DELIVER OR SHIPwoTrees SK1 is an FDM 3D printer with a working area of 256 x 256 x 256 mm and a CoreXY system that can print 3 to 5 times faster than a typical 3D printer. The movements of a CoreXY 3D printer are achieved by moving two motors simultaneously. The TwoTrees SK1 CoreXY 3D printer can print at a maximum speed of 700 mm/s and features automatic Z-Tilt base leveling with a 36-point mesh bed. The print head uses a dual-gear direct extruder to feed the filament directly to the nozzle and the nozzle supports up to 300 degrees Celsius. The printer also comes preloaded with the popular Klipper firmware.TwoTress SK1 3D printer unboxing and assemblyThe 3D printer ships with a range of accessories including tools such as a hex screwdriver, cutting pliers, a brass brush, a microSD card, filament, screw nuts, and so on.Slide Rail and Belt SystemA 4.3-inch color touchscreen display is attached to the top of the printer.A dual-gear direct extruder system feeds the filament directly to the 0.4mm nozzle which can be heated up to 300 degrees. One fan is used to cool the workpiece, and there’s also another high-powered ventilation fan.In order to prevent damage during transportation, each axis of the 3D printer will be locked. So we need to remove the locks before using the machine. We show how to do it in the video embedded at the end of the review.Before turning on the machine for the first time, make sure the correct voltage is selected. There is a switch to adjust to 110V and 220V on the left side of the SK1 3D printer.If the voltage is not set correctly, this happens (110V set when the mains are actually 230V):The power supply blew up but it could be replaced by purchasing a MEANWELL LRS-350-24 power supply available on Amazon, Aliexpress, and other shops for under $30.The WiFi antenna can easily be attached to the SMA connector on the side of the machine using the provided hex key.A PEI magnetic sheet will make sure the workpiece sticks firmly in place and does not fall off during printing. It can be used with a range of plastic materials and is suitable for printing with small surface areas or workpieces that require a smooth bottom surface. Once the print is done, the workpiece will come off easily without having to use tools to take it out.
