Features: 1[Easy To Operate] If you don't know how to use the 3D slicing software, you can directly download the model file (Gcode file) to the Memory Card, insert it into the printer, and start printing. Press the Plus button and put the material in. If you need to replace or remove the material, press the Minus button, wait for a while, and pull it out. After the material is put in, press the play button to start printing. 2[Quick Assembly] The mini 3D printer consists of 3 main parts, which can usually be assembled in 1 minute. You can print the model file in the attachment or download the model file online. If there are multiple model files in the Memory Card, it will print the latest one. 3[High Accuracy] Print size is 4in x 4in x 4in (100x100x100mm) with professional all metal printhead, which ensures the best printing temperature and minimizes printing error rate, suitable for PLA and TPU filaments with 1.75mm diameter. The layer resolution is up to 0.05mm, which ensures the accuracy of the printed model and allows for vivid printing results. 4[Fast Heating] This 3D printer's has a unique button system that allows you to start, stop and easily control the printing process. The nozzle heats up evenly and takes only 5 minutes to a temperature of 180C, meeting the temperature requirements of PLA material pressure. Suitable for beginners. It is also suitable for children, which can develop their interest and improve their spatial imagination and 3D perception. 5[Important Step] Leveling is the most important part of using this printer. Press the home button to start leveling, and when the nozzle touches the magnetic plate, disconnect the power and start leveling. If the printer is not leveled, the magnetic plate may be crushed by the nozzle and damaged. If the nozzle is too far away from the magnetic plate, the printed model will not stick to the plate.
