3D Filament Extruder Machine:Directly convert waste plastic bottles into 3D printing consumables without complicated pretreatment. One standard Coke bottle can be pulled out into about 10 meters of environmentally friendly filaments, reducing the cost of consumables by more than 90% Intelligent Wire Drawing:Integrates heating, temperature control, traction, and winding in one, and starts automatic filament formation with one button. The LCD screen displays temperature/speed in real time, with an error of ±0.05mm. Even novices can get started in 5 minutes. The finished product can be directly used for 3D printing without secondary calibration. <45 decibels. The whole machine weighs 3.2kg, the size of A4 paper, and it is burden-free for dormitory/family use. Wide Compatibility:Supports 300℃ high temperature materials, can adjust the temperature, adapt to different plastics, and meet the diverse needs of professional users. Applicable Scenarios:Suitable for DIY makers and educational experiments. Visually demonstrate the combination of plastic recycling and 3D printing technology, suitable for STEM teaching.
