A. Functional Features 1. **Wide Application Range**: These 3D printer glue sticks can be relatively easily removed from 3D models. They are also applicable to project handicrafts, school projects, art and craft production, etc. 2. **Compatibility**: Suitable for most 3D printer heating beds, including PEI boards, carbon crystal boards, aluminum boards, etc. 3. **Safety**: Made of PVP materials, non - toxic and acid - free, and generally will not cause harm to the human body. The high - viscosity formula has good adhesion to the heating plate or hot bed, which facilitates the removal of the printed model and is suitable for the first layer before printing. 4. **Durability**: One glue stick can usually be used for continuous printing over 100 times. It is practical and helps 3D printing parts adhere to the build plate during the printing process. 5. **Easy to Use and Clean**: Since it is made of water - soluble raw materials, after printing, you can cool the platform and clean it with water. Before use, it is recommended to heat the hot bed first and then evenly apply the glue stick on the platform. After use, cover the lid to prevent the glue stick from drying out. B.
